Dark sky's yeah maybe a timing issue idk maybe it was the kick but it’s recovery was still astounding for an ‘amateur’ build. Without the stabilizer it would of went somewhere but not up lol great recovery is what I have to salute
Hey Pete (Nice Work!) Question? The general trajectory seemed to veer from vertical? Was this intentional? I think the "Seps" looked perfect too! My congrats!
no I think the best launch is this - th-cam.com/video/rvDqoxMUroA/w-d-xo.html&t= but Petr Pavlik made awesome thing - he made 3 steps rocket :) it is very cool!!
Petr, outstanding video presentation. I worked for NASA at Kennedy Space Center for several years of the Space Shuttle program. Your launch views would rival any Shuttle launch I ever worked. I also witnessed dozens of rocket launches from the Cape Canaveral side as well. During one Delta 4 launch, I was assigned to work the beach access road from KSC to Cape Canaveral Air Force Station. About one minute into flight, the rocket exploded, showering debris for a few miles. My personal pickup truck was struck by one of the external boosters restraining straps. It lodged into the roof of my truck causing a brief fire, just narrowly missing the guard shack I was assigned to. The owners of the payload bought me a new truck, and I got to keep my old truck which I turned into a convertible pickup. Anyway, I just wanted to thank you for sharing your video with all of us. It looked as real as any launch I ever witnessed at the Space Center. Keep up the great work! By the way, what country are you in? Thank you again, Petr.
John, I am pleased a lot you like the video of the launch of my rocket model. However, I think there is nothing to beet the true personal experience to watch and listen successful real space rocket launch with your own eyes and ears. But not sure if I have any desire to experience any real rocket launch failure from vicinity. Even some high power rocket models disasters often look horrible but fortunately they usually only look horrible and no harm to people or property happens. I am from Middle of Europe from former Czechoslovakia - now Czech Republic. I live in the country part named Moravia. Regarding placement and usage of on-board camera at rocket model several launch videos published from Space Shuttle program are very inspirational to me - as NASA technicians placed several external on-board cameras at various parts of Space Shuttle including the boosters to document the launch and flight and the whole scenery around. If you like some of the other launches of my similar multistage rocket models are published at the links below. my latest 3 stage rocket ROSON: th-cam.com/video/YOz-HTimVfs/w-d-xo.html 2 stage rocket HERKULES: th-cam.com/video/D66xKCXIUKA/w-d-xo.html th-cam.com/video/um7Ct-K27O8/w-d-xo.html 2(+1) stage rocket HARPOON: th-cam.com/video/kCLbxjvnDWE/w-d-xo.html Thank you for watching and enjoy the rocket model launches and flights.
Petr Pavlík Petr, thank you for your response to my comment. I see the time and dedication that you and your fellow rocketeers put into your love of model rocketing. Were you able to pursue your hobby under the old Soviet regime? I am very happy that you and your friends can openly enjoy doing what you love without fear of being persecuted by the old government. I myself have traveled the world and love the beauty of middle Europe, and it's people. The one greatest thing I see that the internet has done, is to show to all of the world that we are all the same. We work, we play, we are always striving to make better lives for ourselves and our families. The language may be different, but we all want the same things in life. So, my brother, to you and all of your friends, a big thank you from San Antonio, Texas, USA! I look forward to our continued correspondence. Best of luck, and God bless you all!
P.S. My best friend, who I went to Aviation School with, Retired from NASA when the Space Shuttle program came to an end. He is a true Rocket Scientist. I will ask him if he would like to join us for future conversations. I think he could give you more insight into the Shuttle Program and rockets in general. Take care my friend
I love how all the stages and boosters have their own parachutes. I love the gyro stabilization. And the whole system worked! Correct sequence of separation, boosters then the stages. Great stuff!
I think that's the best three stage filming I have ever seen on a small scale rocket. GREAT separations and the fact that they were filmed so clearly is impressive.... AWESOME ! ! !
If you like please have a look at my latest three stage rocket launch - I think you will like the sun shade of the smoke contrails and attractive surroundings around the launch pad: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
Very cool. My big launch was a 12 engine, two stage rocket with six D12-0 engines on the first stage and six D12-3 on the upper to lift an actual 8mm movie camera back in the 70's. It was about 6 feet tall and about 10 inches in diameter guided by a 16 foot launch rod and a 6 foot diameter parachute. The trick was allowing all the lower stages to drop off independently. All the engines fired. Mine did not go nearly as high as yours, but it was great footage and a lot of fun. Oh I forgot, We launched it on the Mall in Washington DC. You could not get away with that today.
My only issue is that it doesn't have 3 stages I only see 2 And no it didn't rise fast and real rockets rise freaking fast The Saturn V is like 40 story's tall (low estimate) Imagine going up 40+ stories in seconds that's fast
It's actually even faster in real life (these videos were slow motion). But, as clayman points out, real rockets rise fast too. It just looks slow because of their size. It's the same reason a 747 looks slower than a Cessna. It's moving much faster in terms of km or miles per hour, but it is moving slower in terms of airplane-lengths per hour, and the latter is all that you have to judge its speed by.

Years ago I did some rockets up myself. I found that if you cut a round hole in the parachute, like real parachutes have, the rocket wouldn't drift as far away, and it didn't swing like a pendulum as it came down. It didn't cause it to far any faster, the air escaping through that hole was about what the swinging back and forth would dump out of the canopy. The hole allowed the air to escape without having to swing, so it came down straighter. On another model in addition to the hole I cut some slits on 1/4 of the canopy all on one side. That caused the parachute to turn in a large slow circle as it descended. It was pretty neat watching it coming down in a straight circular pattern. That was some of the best camera shots I've seen on these. Great work.
As a kid I found Estes in a magazine and the rest is history. I built and launched many rockets. love the hobby. But this video has got to be the coolest I have ever seen AND with sound. Thanks.
+tizoro3 I felt like the whole ksp joke on a model rocket video was unnecessary. I think your harsh comment to 20 day old ksp joke on a model rocket picture is very unnecessary.
tizoro3 I agree. That casual joke that connected two related topics of different fields was highly uncalled for. This is 2017, and jokes are a thing of the past. Since I identify as a transgender herbal, I take offense to that.
I concentrate on various technical functionalities of multistage model rockets rather than the max altitude. If you like please have a look at my TH-cam channel to see some more advanced model rockets. E.g.: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html th-cam.com/video/JMq2dW_V4uw/w-d-xo.html
That's a fantastic system. For me the best part was when you had the staging and propulsion fail and the rocket saved itself--that's some very lovely tech.
My model rocket period came and went, oh, about 45 years ago. What was done with the cameras is a far cry from the ultra fantastical mini film cams we could put on ours. And nobody but the fatalistic would dare chance a a multi-engine launch. Glad this popped up on my feed! Neat!! Only NASA gets more real.
Thank you for your pleasant comment. Superb recordings form on-board camera done by NASA at various launches were great inspiration for my model rockets flight recordings. Maybe you will also like my latest 3 stage model rocket DELTA IV HEAVY Parker solar probe I published here: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html Nice air start of two rocket motors of 3rd stage of ROSON model rocket is beautifully catched here at T 0:40: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html Unique flight recordings are for my model rocket Little Joe I, back then in US at early stage of human space flights there were no similar on-board camera recordings done by NASA, but it could probably look almost identical to my flight recordings: th-cam.com/video/BleKydEyUTQ/w-d-xo.html In case of more interest please have a look at my TH-cam channel. Enjoy.
@@pavlikpetr2010 Thank you very much Petr for the reply. You can bet that I will go to your links. Here in the US I suppose I got in to the model rocket craze of the time. Estes Rockets was the big manufacturer. That's just about all gone now. It's good to learn that Europe still keeps the sport alive. I still have my 'rocket box'.... the launcher I built with the lights and switches and my old tool box full of rocket stuff. A keepsake. I had ALL the fun back in the day. So happens the first rocket I built was the 3.5 foot tall Saturn V. I bought the kit at the Huntsville Space and Rocket Center here in Alabama which is 90 miles from my house. On the way back home I opened the box and my heart fell. So many toilet paper tubes. How to make a rocket out of that??! Nothing after that build ever matched the complexity. Ha! We visited Huntsville at least once a year for many years all through the glory days of the space race. GREAT hearing from you my friend!! Norm
@@OvGraphics Hello Norm, rocket models is great hobby but the number of rocket model enthusiasts is probably shrinking in Europe, I think. The reasons are various, but mostly strict bureaucratic regulations regarding availability of model rocket motor propellants and increasing scarcity of available rocket model airfields suitable for launch. I am also surprised progress of locally being able to purchase professionally fabricated rocket motor for larger rockets D (20Ns) and E (40Ns) type which would be available for affordable price and which would be reliable enough has not improved much during the last 20 or 30 years. I learned bitter lessons last two years when designing and building two multistage rockets propelled by clusters of rocket motors KLIMA D9-P (Made in Germany). I experienced reliability only about 80% to 90%. At first I was impressed by their lightweight and smooth and stable burn of their advanced composite propellant. Finally I learned they were too unreliable often exhibiting malfunction and exploding in the middle of the flight. For multistage rockets it is very dangerous malfunction especially for nearby spectators and of course very disappointing as a lot of fine work invested in the model design and construction is often lost. It can be difficult to attract rocket model beginners to continue in rocketry hobby if they face this type of troubles with basic rocket motors. Hope rocket motors for model rockets will become more reliable in the future so more and more people could enjoy rockets building and successful model rocket launches.
Thank you for watching and your comment. Yes a lot of work and testing and sometimes a good luck is also very helpful. If you like here is my latest three stage rocket launch: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
Thanks. If you like here are some other flights of my 3 and 2 stage rocket models: th-cam.com/video/YOz-HTimVfs/w-d-xo.html th-cam.com/video/-GX4bt3I0-A/w-d-xo.html th-cam.com/video/D2O7nSWT_ZQ/w-d-xo.html
They aren't illiterate retarded clowns. They are bureaucrats that have to keep funding to pet projects and drag projects out longer than necessary in order to keep the people on the project working and to justify the budget. There are serious problems at NASA but calling them names or saying they are stupid is ignorant itself.
Nasa Clowns? Wow, what an ignorant thing to say. It costs money to build rockets and develop new technologies. At least Nasa didn't force engineers to work on their projects like Russia did. And still, to this day, Nasa holds the record for just about everything important, other than the firsts from back in the 50s and early 60s.
Ian Porter They are such government beuerocrat clowns. They extort money from tax payers so they can maintain their bloated salaries for as long as possible, and humanity gets nothing in return. Companies like SpaceX will very soon eclipse NASA. Oh yeah, they also faked the moon landing and continue to lie about it. If what they say they did was true, we should have bases on the moon and mars by now.
SpaceX is SOO fake. Look at this c1.staticflickr.com/1/670/32351549066_3e6f828f16_k.jpg Save it and zoom in nose. You will see remaining ,unphotoshopped part of the wires rocket was obviously lifted down by wires.
First of all, thank you for sharing your impressive deployment and recovery of this seriously complex and challenging rocket. I have a couple questions. 1. Was it planned and engineered for the first and second stage fire or ignition to cause the vehicle to have a slight off centered trajectory? 2. If so what was the reason to shave off what had to be a pretty significant amount of maximum altitude. That says shortest way to get to A-B is in a straight line.
1. It was not planned but this particular rocket has little aerodynamic stability and is therefore very sensitive to wind and any air turbulence. 2. Max altitude flight trajectory is optimum only for some of competition rocket models. For show type or fun type rocket models the optimum trajectory is usually to optimise parachute landing of the rocket stages close enough to the launch site - otherwise pick up or search for too distant landings could be nightmare, especially if a tall vegetation, bushes or forest is nearby and strong wind. Therefore optimum is usually more or less flight trajectory against the wind direction. Here are almost ideal flight trajectories - some of my other three stage and two stage rocket models: th-cam.com/video/YOz-HTimVfs/w-d-xo.html th-cam.com/video/JMq2dW_V4uw/w-d-xo.html th-cam.com/video/-GX4bt3I0-A/w-d-xo.html th-cam.com/video/BleKydEyUTQ/w-d-xo.html In the following case I inclined the launch guiding rod too much against the wind so it almost ended by disaster as the main parachute opened too late for too flat flight trajectory: th-cam.com/video/fD45IvZYev8/w-d-xo.html
Petr Pavlík Thanks for your response, the links and information. I have played with the novice kits. I say played because at that level it’s definitely not something anything close to what the level of your Crafts. If it’s hanging off a rack it’s a hobby play. Your level on the other hand is a enormous degree of knowledge and mathematical calculations and lots of short falls but loads of valuable data and information. So when I say played it not in anyway associated with YOUR VEHICLES OR THOSE OF YOUR CALIBER, no disrespect intended. Have you ever had a active engine vectoring model successfully achieved yet? If not are y’all going to be attempting?
The last time attempt was another kit. I believe it was something similar to a version of THE SUPER CHIEF or THE BIG CHIEF honestly I don’t remember exactly. It was a 2 stage and I do remember the engines because of the altitude I was wanting to get was 1200ft at least but not over 1800-2000ft. They were E-12 -B-6-6. Unfortunately I focus so much on getting the altitude and improperly packed the shoot and cone. Some how between construction, graphics and design and securing the lanyard properly or inspecting it before the launching day. Anyway everything went perfectly fine. Even the deployment of the recovery system was flawless. About 4-7 seconds into the decent the lanyard gave away and the decent speed went from gracefully controlled to artillery incoming and take cover. Impact was terminal and violent but it was a delight up to that point.
I have not attempted any rocket motor vectoring - it will require very sophisticated on-board control, maybe next year or two or so I can try but rather I will never try. But I see many interesting attempts by other rocket model enthusiasts - more or less successful. My next rocket being built right now is similar to FALCONE 9. Estimated test flight in about April to June 2019. The booster will land using rocket motor and landing legs and the second stage will land on parachute. Even though I always try to keep rocket model systems as simple as possible (even though it probably does not look like on my existing multistage rockets) the booster will be extremely complicated piece of classical rocket model building. I am really curious if I have at least some partial success. But because of too many complications and compromises which I had to resolve during design and construction I am not giving it more than about 50% chance for successful launch and landing.
Thanks a lot for your comment.

Excellent rocket and nice videography! My wife and I were in Prague around 1996. My only Czech projectiles come --from-- the superb CZ PCR (75D) and VZ-58!
Of course it is more attractive for spectators to see bigger rocket models. The bigger model means a higher chance to see something unusual. However the bigger model usually also means a higher costs to built.
Thanks for your pleasant comment. These days trying to work in the group of youngsters and with local schools and local youngsters activity center to built hobby rockets and airplanes and other technical marvels for kids.
One rocket motor ROS40 has total impulse 40 N.s (178 lbf.s) and burn out time of about 1.6 sec. This rocket motor was originally developed many years ago for military rocket flares and is still to this time very popular in Middle Europe for use in rocket models. The main propellant is solid based rocket fuel diglykol with starting charge of black powder. Because of the rocket motor small size there is also some kind of flare compound to keep the diglycol compound burning stable. Rocket model 1st stage is propelled by cluster of 4 motors ROS40, 2nd stage by cluster of 2 motors and 3rd stage also by cluster of 2 motors ROS40.

Není to žádná složitá elektronika nebo časovače. Oddělení vyhořelých stupňů a zážeh dalších je řízen/spouštěn jednoduchým akcelerometrem (elektromechanickým - malá magnetka u jazýčkového relé). Jakmile akcelerometr indikuje zpomalování rakety po vyhoření paliva je ihned sepnut obvod pro přepálení/přetavení silonu, který drží stupně rakety pohromadě. Oddělení vyhořelého stupně sepne spínač, který propojí elektrický obvod zážehu palníků motoru dalšího stupně rakety - tento obvod má jednoduchý zpožďovač, cca 0,3s, aby se vyhořelý stupeň dostatečně vzdálil od motorů dalšího stupně a nedošlo k jeho poškození žhavými plyny z trysek. Detailnější popis je uveden u startu také třístupňové rakety - ROSON: th-cam.com/video/YOz-HTimVfs/w-d-xo.html Vše funguje poměrně spolehlivě. Další vícestupňové rakety se stejným systémem řízení oddělení stupňů a zážehu jsou zde: 2 stage rocket HERKULES: th-cam.com/video/D66xKCXIUKA/w-d-xo.html th-cam.com/video/um7Ct-K27O8/w-d-xo.html 2(+1) stage rocket HARPOON: th-cam.com/video/kCLbxjvnDWE/w-d-xo.html
Epic, especially the slow motion video - reminded me of the live Shuttle booster videos as they parachuted downrange, back in the good old days when the USA still cared about space exploration. Great video
That was very well done. I'm interested in the details of your mechanical gyro-vertical which seems VERY useful in stabilizing the vertical orientation of the rocket. I think a lot of hobby rocket people would be interested in such a system, but are intimidated by the mathematics or experimentation required to get the mass of the gyro and angular spin rate high enough to be effective. What motor and battery system are used? What were the mass and dimensions of the gyro flywheel? What materials? Thanks much!
The gyro-vertical is electro-mechanical and its primary function is to initiate deployment of rocket recovery system in apogee. Another important flight safety function is emergency switch-off of all rocket engines ignition in 2nd and 3rd stage and ejection of payload with on board batteries if the rocket axes is more than 50 degrees from vertical. My rather simple gyro-vertical device as built at the moment is not able to control or stabilize rocket flight. In a couple of days I am going to publish on TH-cam the launch of my new 3 stage rocket and I will include a small presentation related to gyro-vertical system. When watching it you will easily figure out its capabilities and maybe improve the system by adding some more advanced electronics to get a feedback for rocket model flight control system. However for the rocket model flight stabilization I would probably rather recommend to go strictly "electronic" way by modifying some of many commercially available 3D GYRO inertial stabilization technologies, which are already in wide use in airplane or helicopter RC models.
Hey thanks for your response, that's unfortunate I thought you maybe had cracked a problem for model rocketry that's been bugging me for some time. I have watched a few youtubers more (and less) successfully use electronic gyro systems (with microcontrollers and servos, often Arduino), but it seems a bit complex, and there are potential legal issues in North America with respect to building what might be considered a "guided" rocket, even if it is a hobby model rocket. It seems like a very open area for research and development for commercialization since many hobby rocketeers have suffered with non-vertical flight problems for decades. But I assume commercial ventures cannot take place because of the legalities of guided rockets.
A Hobby High Power Rocket is legal in the United States. You are correct. If you give it gyro guidance then it becomes a guided missile and you will get a visit from BATF if they become aware that you have done it. Guided Missiles are illegal in the USA. It would not be that difficult to vector thrust by gimbaling the motor using a gyro. Furthermore one can also use cables attached to the trailing fin ailerons for flight guidance after thrust using a gyro. A Two axis system is easiest. Just make sure to front load your system ahead of the Center of Pressure as you Rocket needs to be Top Heavy for stability. I suppose that even fin surfaces ahead of the Center of Pressure make sense as they can be turned to control Pitch, Yaw, and even Roll for guidance of trajectory to a target if one wanted. When they report that Guidance is Internal at professional launches of Guided Missile, it just means that the gyros have been powered up and no longer is Guidance Inertial... Yeah. It can be done. It is not that demanding. A Roll Program can direct your payload to any position you desire within the range of that missile...including malevolent payloads... See why it is illegal? So to make this short I just do not want to end up as a guest at Club Fed's Grey Hotel....Do you?
I agree I'm not looking to build something illegal, BUT I think there is room in the marketplace for a simplified stabilization system which controls only roll and verticality. The explosion of quads on the market has bred a very fertile field of MEMS gyro and accelerometer stabilization systems which could easily be adapted for simple rocket stabilization but of course the law would have to adjust itself to allow this. What a terrible shame, it could absolutely revolutionize the hobby rocket marketplace.
Mark Hunter I agree. If I want to build a Guided Missile, and I can build a guided missile, then there is really no Constitutional Restriction as the Right to Bear Arms shall not be restricted. That Right to Bear Arms when it was written meant State of the Art Weapon Systems. People privately owned Cannon which was State of the Art at the time.. Government began to restrict that right directly after the US Civil War as Privately owned Cannon were used against Union Forces and were integral and necessary for the South's continued insurrection. The BATF is an unconstitutional entity who attempts to regulate the hobby as they consider it a threat to Government. Guided Missiles can shoot down aircraft, take out infrastructure like Oil Refineries and Power Plants, etc.. The National Association of Rocketry have been in legal battles with the BATF due to unreasonable and arbitrary restrictions...which are unlawful. *Be careful in your responses. The Federal Government does retaliate for publishing criticism of the BATF. Freedom of Speech is restricted and these people do not follow the US Constitution.* For example///The last time I flew I was strip searched and I no longer fly alone due to criticism. Now an Air Marshall accompanies me. They do retaliate. (I have never once did anything against the Government and I am not criminal. Hell. I am a PACIFIST. But knowledge is dangerous. And they do not want you to think.) Yes it is THAT BAD. And all I criticized was the arbitrary regulations of the 62.5 Gram propellant limit of Aluminum Percolate Composite Propellant which was at the heart of the NAR suit. (Would 62.6 grams make a difference? Do you see how that is arbitrary? The wanted to reduce propellant from a maximum of 125 Grams and just decided to cut it in half for no real reason. Damned Patriot Acts.) BATF also declared APCP as "explosive" which it is not. Of course any substance that can be rapidlyoxidized is explosive when contained. But APCP does not explode in open air nor will it if it is attempted to be detonated by percussion like the High Explosives. As for me I will continue to publish until I am caged...or dead. I no longer care.
Thanks for watching and your comment. I am often surprised only a rocket model with cheap action camera on-board can catch interesting flight scenes. When in slow-motion sometimes looking realistic as real rocket flights, which scenes I like the most. From many published on-board camera real spacecraft take-off recordings I recommend e.g. the following: th-cam.com/video/cLl7oqdm_B8/w-d-xo.html Powerful rocket engines smoke trails on the background of beautiful Earth, blue skyline and deep black Universe. Always fascinating to me. Enjoy.
Matyniov if that is the case it's called preemptive strike and it has been actually contemplated lately. So it could happen but they wouldn't launch any nuclear missle
Not only was it a lovely flight, but I have to say, that is one of the most beautiful looking rockets I think i've ever seen. Also, very futuristic looking.
The maximum height of the flight was not anything special - the apogee was at 675 m (2214 feet) above the ground. This rocket belongs to the class of high power rocket models but it is rather small rocket. The lift off mass is about 2.8 kg (6.17 lb) and length about 1.5 m (5 ft). The most powerful rocket model I built so far is the following three stage rocket model: th-cam.com/video/YOz-HTimVfs/w-d-xo.html However it is also small rocket model regarding the other high power rocket models of the other rocket model enthusiasts. I recommend you watch take-off and flight video of truly High power rocket model (it is not my rocket) - there you will see the darkness of space and the curve of the earth for sure: th-cam.com/video/qY7W3EMfrgc/w-d-xo.html Fascinating supersonic flight at the edge of the outer space.

Built from scratch as any other of my rocket models. I am not sure how many hours I spent building this rocket, maybe around 300 hours in rocket model workshop. But if not including the design and development time and provided there are perfect construction plans for every detail (so I need not often go trial and error) it could be probably much less. Real scale models (mock-up) of rockets often seen at some competitions take significantly more time to build - usually thousands of workshop hours. Rocket motors can be expensive but I use only cheap rocket motors ROS40 popular in Middle Europe for rocket models. Construction material purchase price is about 150 to 200 USD including wood, paint, glue, epoxy, electronic components, .... One on-board mini camera can be for about 100 to 200 USD. But if you want to begin building and flying with rocket models you should probably start with simple single stage rockets. Multistage rocket models are very elaborate flying machines and if not designed and built properly and carefully they usually do not survive first test flight - and last but not least can also be dangerous.

Petr Pavlík coming back to this 2 years later, I’m absolutely appreciative on your response. It’s a beautiful piece of rocketry you make. And we are all so appreciative that you spend more time making videos to show your progress. Thank you.
Thanks for your pleasant comment. If you like have a look at my TH-cam channel for several more multistage model rocket videos. My latest three stage DELTA IV HEAVY: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html Or several years old Little Joe I: th-cam.com/video/BleKydEyUTQ/w-d-xo.html The most crazy project was and still is SPACEX FALCON 9 CREW DRAGON: th-cam.com/video/UqtFCBpdMwc/w-d-xo.html
Bretton Ferguson yh but those are relatively simple. they do also have some Iranian made rockets too, around 5 meters long. They launch a couple at Jerusalem and Tel-Aviv but shot down.
At the end of the day, I can't blame Hamas or the People of Israel!! I mean, the fight is gone for more than 2 generations!! They will hate each other and none knows how it all started!!
That was very cool.. I really liked everything from the smoke charges to simulate the launch sequence to the multiple cameras that captured the stages and trajectory. I’m only now getting back into the hobby after 40 or so years from when I last built and launched model rockets. A childhood friend of mine was given a trunk load of engines (up to D-12), and when I was visiting him he couldn’t wait to share them by taking my girlfriend and I out to a local field to launch the kits with his kids... It brought back SO many childhood memories that I’m now building the original Estes Saturn V kit from the early 70’s that I found on EBay! I’d love to learn more about the electronics used to get the multiple engines to ignite at the same time as well as those used to trip the parachutes and other stages... not to mention the gyros to keep the rocket pointed up. Incredible how far the hobby has grown in the 4 or so decades when I was building and launching them. Thanks again for sharing this video!
There is not any active on-board stabilizer system - only the passive stabilization by tail fins and correct position of the rocket centre of gravity.. The primary function of gyro-vertical is to initiate deployment of rocket recovery system in apogee. Another important flight safety function is emergency switch-off of all rocket engines ignition in 2nd (and 3rd stage for 3 stage rockets) and ejection of payload with on board batteries if the rocket axes is more than 50 degrees out of vertical. My rather simple gyro-vertical device as built at the moment is not able to control or stabilize rocket flight direction. I am using only mechanical system of deployment just eliminating any ejection charge. The booster is pushed out to the side by bamboo spring and hold in place by nylon fishing line. Booster separation is initiated by deceleration sensor which switches on simple electric circuit which heats up small resistance coil which in a fraction of second burns/cuts the binding nylon line. The nose cone is pushed out by small steel leaf spring located at the outer edge of the cone and hold in place by short pin protruding out of the inner edge of the nose cone into the hole in the rocket body tube. As soon as the booster turns out of the rocket body tube the pin runs out of the hole in the rocket body tube releasing the nose cone. The three small parachutes inside each booster are located just behind the nose cone and they are self-ejected during the booster rotation at the time of booster separation. maybe you can see it in more detailed view in slow motion video of launch of my two stage rocket with larger boosters: th-cam.com/video/-GX4bt3I0-A/w-d-xo.html The second stage has the same separation initiation by heat-cutting nylon fishing line but it is pushed down from the third stage by styrofoam piston driven by rubber bands. When the piston inside the second stage starts moving up it also deploys cylinder container with the second stage parachute. The same principle is used for the third stage main parachute and payload deployment but it is initiated by signal from electro-mechanical gyro-vertical when the third stage hull axes reaches horizontal position at apogee. This system of deployment works fine for rather "small" and "slow" rocket models. It might not work right for any rocket model reaching supersonic speed of flight in case of need of parachute emergency ejection. More technical details about the gyro-vertical and its function presentation is published at the end of another three stage rocket launch video: th-cam.com/video/YOz-HTimVfs/w-d-xo.html Interesting flight of the same rocket also here: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html Another staging rocket model which can be of your interest: th-cam.com/video/BleKydEyUTQ/w-d-xo.html In this case I use active stabilization by mechanical gyro which is to prevent or reduce rocket spin - the main goal is to keep the on-board cameras video stable without disturbing spin. The mechanical gyro principle is almost identical to the function of Rolleron used earlier in military e.g. for Sidewinder missile spin elimination. I recommend you get in touch with some of your local rocketry club or group of enthusiasts to get some ideas about advanced electronics used for e.g. dual deployment, staging and parachute ejection in case you would like to incorporate it in your rocket models. My rather simple home-built elektronics is difficult to duplicate without detailed plans and some experience and it is more or less just for inspiration. It is usually a lot of fun to participate in some of rocket model meets and gather launch field experience. Welcome back in the world of rocketry and enjoy your rocket models.
Probably correct. Only 4 rocket engines are ignited at launch - 2 engines in each booster. After both boosters burnout and their separation the ignition of the next stage takes place.
No the .5 is only added for rockets that keep engines attached after they run out of fuel. The rocket was made of 3 groups that were detached by the end, it was indeed a 3 stage rocket.
Thanks for your comment and clarification of so-called .5 stage rocket. My other rocket model HARPOON is 2.5 stage rocket - the second stage of HARPOON model has cluster of 4 rocket motors ignited in sequence in groups of two motors. After ejection of 1st stage the 2nd stage has ignition of 2 rocket motors and after their burnout they are not jettisoned and the last 2 rocket motors are ignited. The 2nd stage returns to earth on parachutes with all 4 burnout rocket motors: th-cam.com/video/kCLbxjvnDWE/w-d-xo.html My latest 3 stage rocket launch if you like to have a look is published here: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
The maximum height of the flight was not anything special - around 600 m (2000 feet) above the ground. This rocket belongs to the class of high power rocket models but it is rather small rocket. It is also small rocket model regarding the other high power rocket models of the other rocket model enthusiasts. I recommend you watch take-off and flight video of truly High power rocket model (it is not my rocket) - there you will see the darkness of space and the curve of the earth for sure: th-cam.com/video/qY7W3EMfrgc/w-d-xo.html Fascinating supersonic flight at the edge of the outer space.
Wow..I don't know much about these rockets but Ive watched a few on TH-cam and this rocket seemed to go up very straight. Not too much of the typycal spinning you see so often which was great for viewing. Good job guys. Thanx for the show! 🚀
Beautiful parallel booster Rockets! I have not tried this myself, only two stage sounding Rocket using F-1 Engines. Highest altitude so far 1500 Meters but working on reaching higher. Great Job! Love it! Thank You!
Best video & demonstration of model rocketry that I have ever seen, period. I can only guess at the huge untold number of hours it must have taken to achieve this success! And, also one of the number of learning steps that accompanies such successes. Fantastic! I look forward to seeing where you've gone in 4 years since. Big thumbs up!
I am happy you like the video of my three stage rocket model launch several years ago. It was my first 3 stage rocket model and due to several necessary functional design development modifications it does not look too neat. However it is reliable rocket model but too ,,expensive" timewise to prepare for the launch and too sensitive to wind gusts during the flight.

Heya Petr! Absolutely wonderful. Loved the pre-ignition smoke simulation, the booster drop(3 chutes each!), stage separation, apogee arc over, booster cam viewpoint and it was wonderful to see your fellow rocketeers at Klub Praha (go Sat 5 B!). Fantastic accomplishment. Thanks for the inspiration and keep up the great work.
Thank you for your high rating - I am pleased a lot you like the video. Hope you found some tips useful for your model rocketry or other activity.

Late last week, God gave me a dream about 2 6 foot tall model rockets being assembled inside what looked like a high school gymnasium, and I remember telling someone I was with that it would really be cool if what they were doing really took off, and the could hire us to work with them. Be richly blessed!!!

I started with airplanes when I was a small boy.

Thank you for your comment. In some of my rocket launch videos I published full speed flight recordings just for fun, but I am afraid it is too fast to watch. For example have a look at the launch of three stage rocket ROSON: th-cam.com/video/YOz-HTimVfs/w-d-xo.html from about T 3:40 there is launch in original speed of the recording: th-cam.com/video/YOz-HTimVfs/w-d-xo.html?t=220 I prefer slow-mo because it looks more realistic. And to be as realistic as possible is the goal of most of rocket models. Another launch where is also included full speed recording is the following video of the launch of 2 stage rocket HERKULES: th-cam.com/video/D66xKCXIUKA/w-d-xo.html or here: th-cam.com/video/um7Ct-K27O8/w-d-xo.html
Thank you. If you like here is my latest 3-stage model rocket DELTA IV HEAVY Parker Solar Probe: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html But the most successful with many perfect repeat launches long term is my 3-stage rocket I designed and built shortly after my first 3-stage rocket: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html The most difficult to achieve are these moments of the launch - recorded air start of the 3rd stage cluster of 2 rocket motors: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html?t=38

Very nice job of stabilized flight and engine ignition in staging. Especially with the large gap or space between the stages. I've never seen that before. Very Cool! Thanks
What a fantastic video. You guys did a great job on both rocket and the film. Had a moment of déjà vu and could almost smell the dope. LOL used to use that stuff a lot in the grade school hobby class. Makes me want to go out and build another rocket.
It's nice to see so many rocket enthusiasts share in such widespread success. Perhaps, if NASA sought your input....they'd be able to finally launch the issue plagued and often delayed STS. Well done!
Thank you for your comment. It was my first three stage model rocket. And as apparent overall design beauty suffered from necessary addition of more rocket motors to get the rocket takeoff more reliable and stable and also adding some smoke charges to do the ,,show" for audience. If you like here is my last year launch of model rocket DELTA IV HEAVY built as three stage model: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html Probably worth seeing is also another of my previous launches of three stage rockets: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html
Soooo....you guys are a bit serious about these things, huh? LOL...GREAT job, awesome footage. I spent a lot of time with model rockets when I was a teen, but the best one could hope for then was a blurry and grainy 110 film snap at apogee, this stuff amazes me. Post more! Thanks!

You need funding and you can go well into space. You earned a subscriber. I dream of building a rocket similar. You need to be a teacher for rockets, unless you already are. Your designs are very inspiring.
Very nice job, it all worked flawlessly. Congratulations. I built rockets as a teenager, but not as complicated as this. Very enjoyable. Thanks for the video.

This is without a doubt the most stable ascent and smoothest staging I have ever seen. It was on the NASA professional level. Well done sir.
The side boosters jettisoning almost flipped the rocket....
Dark sky's yet it didn’t.
@@5777Whatup no, no it didn't, but there was nothing smooth about the 1st stage jettisoning lol
Dark sky's yeah maybe a timing issue idk maybe it was the kick but it’s recovery was still astounding for an ‘amateur’ build. Without the stabilizer it would of went somewhere but not up lol great recovery is what I have to salute
great job
Absolute best model rocket launch vehicle I have ever watched on TH-cam. This is absolute highest pro level stuff on so many levels.
You should check out “bps space”on TH-cam
Yeah check out bps space
Probably the best model rocket launch vehicle I have ever watched. Awesome.
Thank you and enjoy. If you like see my latest 3 stage rocket model launch: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
Hey Pete (Nice Work!) Question? The general trajectory seemed to veer from vertical? Was this intentional? I think the "Seps" looked perfect too! My congrats!
Very smooth! Let's build a jumbo and a space station! ;)

*FWOOOOSH*
no
I think the best launch is this - th-cam.com/video/rvDqoxMUroA/w-d-xo.html&t=
but Petr Pavlik made awesome thing - he made 3 steps rocket :) it is very cool!!
Petr, outstanding video presentation. I worked for NASA at Kennedy Space Center for several years of the Space Shuttle program. Your launch views would rival any Shuttle launch I ever worked. I also witnessed dozens of rocket launches from the Cape Canaveral side as well. During one Delta 4 launch, I was assigned to work the beach access road from KSC to Cape Canaveral Air Force Station. About one minute into flight, the rocket exploded, showering debris for a few miles. My personal pickup truck was struck by one of the external boosters restraining straps. It lodged into the roof of my truck causing a brief fire, just narrowly missing the guard shack I was assigned to. The owners of the payload bought me a new truck, and I got to keep my old truck which I turned into a convertible pickup.
Anyway, I just wanted to thank you for sharing your video with all of us. It looked as real as any launch I ever witnessed at the Space Center.
Keep up the great work! By the way, what country are you in?
Thank you again, Petr.
John, I am pleased a lot you like the video of the launch of my rocket model. However, I think there is nothing to beet the true personal experience to watch and listen successful real space rocket launch with your own eyes and ears. But not sure if I have any desire to experience any real rocket launch failure from vicinity. Even some high power rocket models disasters often look horrible but fortunately they usually only look horrible and no harm to people or property happens.
I am from Middle of Europe from former Czechoslovakia - now Czech Republic. I live in the country part named Moravia.
Regarding placement and usage of on-board camera at rocket model several launch videos published from Space Shuttle program are very inspirational to me - as NASA technicians placed several external on-board cameras at various parts of Space Shuttle including the boosters to document the launch and flight and the whole scenery around.

Petr Pavlík Petr, thank you for your response to my comment. I see the time and dedication that you and your fellow rocketeers put into your love of model rocketing. Were you able to pursue your hobby under the old Soviet regime? I am very happy that you and your friends can openly enjoy doing what you love without fear of being persecuted by the old government.
I myself have traveled the world and love the beauty of middle Europe, and it's people. The one greatest thing I see that the internet has done, is to show to all of the world that we are all the same. We work, we play, we are always striving to make better lives for ourselves and our families. The language may be different, but we all want the same things in life.
So, my brother, to you and all of your friends, a big thank you from San Antonio, Texas, USA! I look forward to our continued correspondence.
Best of luck, and God bless you all!
P.S. My best friend, who I went to Aviation School with,
Retired from NASA when the Space Shuttle program came to an end. He is a true Rocket Scientist. I will ask him if he would like to join us for future conversations. I think he could give you more insight into the Shuttle Program and rockets in general.
Take care my friend

No delta 4 ever exploded, however your story is mostly consistent with a delta 2 explosion 17 seconds after launch in 1997.
I love how all the stages and boosters have their own parachutes. I love the gyro stabilization. And the whole system worked! Correct sequence of separation, boosters then the stages. Great stuff!
Michael Escobar they have cheap gyro stabilization with fidget spinners!!!!!! My most hated toy
@@KerbalChris There is a positive side to fidget spinners: small ball bearings are now cheaper.
I think that's the best three stage filming I have ever seen on a small scale rocket. GREAT separations and the fact that they were filmed so clearly is impressive.... AWESOME ! ! !
Excellent rocket control. Steady vertical lift off with no spins. Very good camera placement and good quality of video. Thanks

Very cool. My big launch was a 12 engine, two stage rocket with six D12-0 engines on the first stage and six D12-3 on the upper to lift an actual 8mm movie camera back in the 70's. It was about 6 feet tall and about 10 inches in diameter guided by a 16 foot launch rod and a 6 foot diameter parachute. The trick was allowing all the lower stages to drop off independently. All the engines fired. Mine did not go nearly as high as yours, but it was great footage and a lot of fun. Oh I forgot, We launched it on the Mall in Washington DC. You could not get away with that today.
I had a big bertha
Very nice launch, good preparation, excellent camera work. Thank you.
Why did it rise so fast? Don’t real rockets rise slowly?
My only issue is that it doesn't have 3 stages I only see 2
And no it didn't rise fast and real rockets rise freaking fast
The Saturn V is like 40 story's tall (low estimate)
Imagine going up 40+ stories in seconds that's fast
It's actually even faster in real life (these videos were slow motion). But, as clayman points out, real rockets rise fast too. It just looks slow because of their size. It's the same reason a 747 looks slower than a Cessna. It's moving much faster in terms of km or miles per hour, but it is moving slower in terms of airplane-lengths per hour, and the latter is all that you have to judge its speed by.
This was unquestionably the best rocketry video I have ever seen. (And I have seen many.)
Thanks for your pleasant comment.

Years ago I did some rockets up myself. I found that if you cut a round hole in the parachute, like real parachutes have, the rocket wouldn't drift as far away, and it didn't swing like a pendulum as it came down. It didn't cause it to far any faster, the air escaping through that hole was about what the swinging back and forth would dump out of the canopy. The hole allowed the air to escape without having to swing, so it came down straighter.
On another model in addition to the hole I cut some slits on 1/4 of the canopy all on one side. That caused the parachute to turn in a large slow circle as it descended.
It was pretty neat watching it coming down in a straight circular pattern.
That was some of the best camera shots I've seen on these. Great work.
This makes my ten year old self very happy. Thanks for the memories.
As a kid I found Estes in a magazine and the rest is history. I built and launched many rockets. love the hobby. But this video has got to be the coolest I have ever seen AND with sound. Thanks.
Better than my rockets in KSP
Nah I just got done landing on Moho so my KSP rockets are legit lol
JonnyBlaze2006 Ok? Such an unnecessary comment.
+tizoro3 I felt like the whole ksp joke on a model rocket video was unnecessary. I think your harsh comment to 20 day old ksp joke on a model rocket picture is very unnecessary.
tizoro3 I agree. That casual joke that connected two related topics of different fields was highly uncalled for. This is 2017, and jokes are a thing of the past. Since I identify as a transgender herbal, I take offense to that.
jokes are a thing of the past.....wth????
Outstanding looking rocket, launch and flight video, looks industry funded. The best and most professional-looking I've ever seen on TH-cam.
That was brilliant, and you, my friend, are a steely-eyed missile-man!
At first was a little disappointed at the altitude achieved by a three stage rocket, but when shown the size compared to a person, very well done.
I concentrate on various technical functionalities of multistage model rockets rather than the max altitude.
If you like please have a look at my TH-cam channel to see some more advanced model rockets.

why doesn't this have a million views? great job!
It does.
I totally agree with Gunther Novacrunch... THE best rocket launch and flight video! Love it!!
That's a fantastic system. For me the best part was when you had the staging and propulsion fail and the rocket saved itself--that's some very lovely tech.
My model rocket period came and went, oh, about 45 years ago. What was done with the cameras is a far cry from the ultra fantastical mini film cams we could put on ours. And nobody but the fatalistic would dare chance a a multi-engine launch. Glad this popped up on my feed! Neat!! Only NASA gets more real.
Thank you for your pleasant comment. Superb recordings form on-board camera done by NASA at various launches were great inspiration for my model rockets flight recordings.
Maybe you will also like my latest 3 stage model rocket DELTA IV HEAVY Parker solar probe I published here: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html

@@pavlikpetr2010 Thank you very much Petr for the reply. You can bet that I will go to your links. Here in the US I suppose I got in to the model rocket craze of the time. Estes Rockets was the big manufacturer. That's just about all gone now. It's good to learn that Europe still keeps the sport alive. I still have my 'rocket box'.... the launcher I built with the lights and switches and my old tool box full of rocket stuff. A keepsake. I had ALL the fun back in the day. So happens the first rocket I built was the 3.5 foot tall Saturn V. I bought the kit at the Huntsville Space and Rocket Center here in Alabama which is 90 miles from my house. On the way back home I opened the box and my heart fell. So many toilet paper tubes. How to make a rocket out of that??! Nothing after that build ever matched the complexity. Ha! We visited Huntsville at least once a year for many years all through the glory days of the space race.
GREAT hearing from you my friend!!

@@OvGraphics Hello Norm, rocket models is great hobby but the number of rocket model enthusiasts is probably shrinking in Europe, I think. The reasons are various, but mostly strict bureaucratic regulations regarding availability of model rocket motor propellants and increasing scarcity of available rocket model airfields suitable for launch. I am also surprised progress of locally being able to purchase professionally fabricated rocket motor for larger rockets D (20Ns) and E (40Ns) type which would be available for affordable price and which would be reliable enough has not improved much during the last 20 or 30 years. I learned bitter lessons last two years when designing and building two multistage rockets propelled by clusters of rocket motors KLIMA D9-P (Made in Germany). I experienced reliability only about 80% to 90%. At first I was impressed by their lightweight and smooth and stable burn of their advanced composite propellant. Finally I learned they were too unreliable often exhibiting malfunction and exploding in the middle of the flight. For multistage rockets it is very dangerous malfunction especially for nearby spectators and of course very disappointing as a lot of fine work invested in the model design and construction is often lost. It can be difficult to attract rocket model beginners to continue in rocketry hobby if they face this type of troubles with basic rocket motors.
Hope rocket motors for model rockets will become more reliable in the future so more and more people could enjoy rockets building and successful model rocket launches.
Pretty amazing setup. I'm impressed. That took some real work.
Thank you for watching and your comment. Yes a lot of work and testing and sometimes a good luck is also very helpful.

Absolutely Awesome! I launched model rockets as a kid and you brought back great memories, thanks.
Fantastic you can work for NASA. Keep up the great work.
For Nasa clowns? you kidding me.
They aren't illiterate retarded clowns. They are bureaucrats that have to keep funding to pet projects and drag projects out longer than necessary in order to keep the people on the project working and to justify the budget. There are serious problems at NASA but calling them names or saying they are stupid is ignorant itself.
Nasa Clowns? Wow, what an ignorant thing to say. It costs money to build rockets and develop new technologies. At least Nasa didn't force engineers to work on their projects like Russia did. And still, to this day, Nasa holds the record for just about everything important, other than the firsts from back in the 50s and early 60s.
Ian Porter They are such government beuerocrat clowns. They extort money from tax payers so they can maintain their bloated salaries for as long as possible, and humanity gets nothing in return. Companies like SpaceX will very soon eclipse NASA. Oh yeah, they also faked the moon landing and continue to lie about it. If what they say they did was true, we should have bases on the moon and mars by now.
SpaceX is SOO fake. Look at this c1.staticflickr.com/1/670/32351549066_3e6f828f16_k.jpg Save it and zoom in nose. You will see remaining ,unphotoshopped part of the wires rocket was obviously lifted down by wires.
This is one of the COOLEST model rocket videos I've ever seen. THANKS!
Good work, great photography. I am there with you in spirit!
First time I've ever seen parallel plus serial staging on a model rocket! Brilliant launch!
First of all, thank you for sharing your impressive deployment and recovery of this seriously complex and challenging rocket. I have a couple questions.
1. Was it planned and engineered for the first and second stage fire or ignition to cause the vehicle to have a slight off centered trajectory?
2. If so what was the reason to shave off what had to be a pretty significant amount of maximum altitude. That says shortest way to get to A-B is in a straight line.
1. It was not planned but this particular rocket has little aerodynamic stability and is therefore very sensitive to wind and any air turbulence.
2. Max altitude flight trajectory is optimum only for some of competition rocket models. For show type or fun type rocket models the optimum trajectory is usually to optimise parachute landing of the rocket stages close enough to the launch site - otherwise pick up or search for too distant landings could be nightmare, especially if a tall vegetation, bushes or forest is nearby and strong wind. Therefore optimum is usually more or less flight trajectory against the wind direction.
Here are almost ideal flight trajectories - some of my other three stage and two stage rocket models:

In the following case I inclined the launch guiding rod too much against the wind so it almost ended by disaster as the main parachute opened too late for too flat flight trajectory:

Thanks for your response, the links and information. I have played with the novice kits. I say played because at that level it’s definitely not something anything close to what the level of your Crafts. If it’s hanging off a rack it’s a hobby play. Your level on the other hand is a enormous degree of knowledge and mathematical calculations and lots of short falls but loads of valuable data and information. So when I say played it not in anyway associated with YOUR VEHICLES OR THOSE OF YOUR CALIBER, no disrespect intended. Have you ever had a active engine vectoring model successfully achieved yet? If not are y’all going to be attempting?
The last time attempt was another kit. I believe it was something similar to a version of THE SUPER CHIEF or THE BIG CHIEF honestly I don’t remember exactly. It was a 2 stage and I do remember the engines because of the altitude I was wanting to get was 1200ft at least but not over 1800-2000ft. They were E-12 -B-6-6. Unfortunately I focus so much on getting the altitude and improperly packed the shoot and cone. Some how between construction, graphics and design and securing the lanyard properly or inspecting it before the launching day. Anyway everything went perfectly fine. Even the deployment of the recovery system was flawless. About 4-7 seconds into the decent the lanyard gave away and the decent speed went from gracefully controlled to artillery incoming and take cover. Impact was terminal and violent but it was a delight up to that point.
I have not attempted any rocket motor vectoring - it will require very sophisticated on-board control, maybe next year or two or so I can try but rather I will never try. But I see many interesting attempts by other rocket model enthusiasts - more or less successful. My next rocket being built right now is similar to FALCONE 9. Estimated test flight in about April to June 2019. The booster will land using rocket motor and landing legs and the second stage will land on parachute. Even though I always try to keep rocket model systems as simple as possible (even though it probably does not look like on my existing multistage rockets) the booster will be extremely complicated piece of classical rocket model building. I am really curious if I have at least some partial success. But because of too many complications and compromises which I had to resolve during design and construction I am not giving it more than about 50% chance for successful launch and landing.
Wonderful videos !!!!! I wish you much luck with your upcoming rocket. I will be looking forward to seeing the results.
I also think this is the best video of a rocket launch I have ever seen, not the highest, but clearly well thought out.

I was happy when my rockets did not head for a neighbors house! This was great!
Excellent rocket and nice videography! My wife and I were in Prague around 1996.
My only Czech projectiles come --from-- the superb CZ PCR (75D) and VZ-58!
Does the person with the biggest rocket get angry when another show up with his rocket and it is even bigger? Or does size really matter?
Of course it is more attractive for spectators to see bigger rocket models. The bigger model means a higher chance to see something unusual. However the bigger model usually also means a higher costs to built.
Petr Pavlík nice👍👍👍👍👍
nattsurfaren size always matters✌
that guy at the the end with the Saturn V... I want to see that one launch!
Sometimes, a rocket is just a rocket.
Remarkable - Thank you for your Time/Effort/Contribution that has undoubtedly piqued youngsters interest in STEM/Rocketry worldwide! Mike
Thanks for your pleasant comment.
These days trying to work in the group of youngsters and with local schools and local youngsters activity center to built hobby rockets and airplanes and other technical marvels for kids.
Incredible video! What is the thrust rating on those ROS40 engines?
One rocket motor ROS40 has total impulse 40 N.s (178 lbf.s) and burn out time of about 1.6 sec. This rocket motor was originally developed many years ago for military rocket flares and is still to this time very popular in Middle Europe for use in rocket models. The main propellant is solid based rocket fuel diglykol with starting charge of black powder. Because of the rocket motor small size there is also some kind of flare compound to keep the diglycol compound burning stable. Rocket model 1st stage is propelled by cluster of 4 motors ROS40, 2nd stage by cluster of 2 motors and 3rd stage also by cluster of 2 motors ROS40.

Sorry for my mistake in units conversion from metric in my reply above: Correct conversion of the total impulse should be 40 N.s = 9 lbf.s
My apology.
Není to žádná složitá elektronika nebo časovače. Oddělení vyhořelých stupňů a zážeh dalších je řízen/spouštěn jednoduchým akcelerometrem (elektromechanickým - malá magnetka u jazýčkového relé). Jakmile akcelerometr indikuje zpomalování rakety po vyhoření paliva je ihned sepnut obvod pro přepálení/přetavení silonu, který drží stupně rakety pohromadě. Oddělení vyhořelého stupně sepne spínač, který propojí elektrický obvod zážehu palníků motoru dalšího stupně rakety - tento obvod má jednoduchý zpožďovač, cca 0,3s, aby se vyhořelý stupeň dostatečně vzdálil od motorů dalšího stupně a nedošlo k jeho poškození žhavými plyny z trysek.

Epic, especially the slow motion video - reminded me of the live Shuttle booster videos as they parachuted downrange, back in the good old days when the USA still cared about space exploration. Great video
That was very well done. I'm interested in the details of your mechanical gyro-vertical which seems VERY useful in stabilizing the vertical orientation of the rocket. I think a lot of hobby rocket people would be interested in such a system, but are intimidated by the mathematics or experimentation required to get the mass of the gyro and angular spin rate high enough to be effective. What motor and battery system are used? What were the mass and dimensions of the gyro flywheel? What materials? Thanks much!
The gyro-vertical is electro-mechanical and its primary function is to initiate deployment of rocket recovery system in apogee. Another important flight safety function is emergency switch-off of all rocket engines ignition in 2nd and 3rd stage and ejection of payload with on board batteries if the rocket axes is more than 50 degrees from vertical. My rather simple gyro-vertical device as built at the moment is not able to control or stabilize rocket flight. In a couple of days I am going to publish on TH-cam the launch of my new 3 stage rocket and I will include a small presentation related to gyro-vertical system. When watching it you will easily figure out its capabilities and maybe improve the system by adding some more advanced electronics to get a feedback for rocket model flight control system. However for the rocket model flight stabilization I would probably rather recommend to go strictly "electronic" way by modifying some of many commercially available 3D GYRO inertial stabilization technologies, which are already in wide use in airplane or helicopter RC models.
Hey thanks for your response, that's unfortunate I thought you maybe had cracked a problem for model rocketry that's been bugging me for some time. I have watched a few youtubers more (and less) successfully use electronic gyro systems (with microcontrollers and servos, often Arduino), but it seems a bit complex, and there are potential legal issues in North America with respect to building what might be considered a "guided" rocket, even if it is a hobby model rocket. It seems like a very open area for research and development for commercialization since many hobby rocketeers have suffered with non-vertical flight problems for decades. But I assume commercial ventures cannot take place because of the legalities of guided rockets.
A Hobby High Power Rocket is legal in the United States.
You are correct. If you give it gyro guidance then it becomes a guided missile and you will get a visit from BATF if they become aware that you have done it. Guided Missiles are illegal in the USA.
It would not be that difficult to vector thrust by gimbaling the motor using a gyro. Furthermore one can also use cables attached to the trailing fin ailerons for flight guidance after thrust using a gyro. A Two axis system is easiest. Just make sure to front load your system ahead of the Center of Pressure as you Rocket needs to be Top Heavy for stability.
I suppose that even fin surfaces ahead of the Center of Pressure make sense as they can be turned to control Pitch, Yaw, and even Roll for guidance of trajectory to a target if one wanted.
When they report that Guidance is Internal at professional launches of Guided Missile, it just means that the gyros have been powered up and no longer is Guidance Inertial...
Yeah. It can be done. It is not that demanding. A Roll Program can direct your payload to any position you desire within the range of that missile...including malevolent payloads... See why it is illegal?
So to make this short I just do not want to end up as a guest at Club Fed's Grey Hotel....Do you?
I agree I'm not looking to build something illegal, BUT I think there is room in the marketplace for a simplified stabilization system which controls only roll and verticality. The explosion of quads on the market has bred a very fertile field of MEMS gyro and accelerometer stabilization systems which could easily be adapted for simple rocket stabilization but of course the law would have to adjust itself to allow this. What a terrible shame, it could absolutely revolutionize the hobby rocket marketplace.
Mark Hunter I agree.
If I want to build a Guided Missile, and I can build a guided missile, then there is really no Constitutional Restriction as the Right to Bear Arms shall not be restricted. That Right to Bear Arms when it was written meant State of the Art Weapon Systems. People privately owned Cannon which was State of the Art at the time..
Government began to restrict that right directly after the US Civil War as Privately owned Cannon were used against Union Forces and were integral and necessary for the South's continued insurrection.
The BATF is an unconstitutional entity who attempts to regulate the hobby as they consider it a threat to Government. Guided Missiles can shoot down aircraft, take out infrastructure like Oil Refineries and Power Plants, etc..
The National Association of Rocketry have been in legal battles with the BATF due to unreasonable and arbitrary restrictions...which are unlawful.
*Be careful in your responses. The Federal Government does retaliate for publishing criticism of the BATF. Freedom of Speech is restricted and these people do not follow the US Constitution.*
For example///The last time I flew I was strip searched and I no longer fly alone due to criticism. Now an Air Marshall accompanies me. They do retaliate. (I have never once did anything against the Government and I am not criminal. Hell. I am a PACIFIST. But knowledge is dangerous. And they do not want you to think.)
Yes it is THAT BAD. And all I criticized was the arbitrary regulations of the 62.5 Gram propellant limit of Aluminum Percolate Composite Propellant which was at the heart of the NAR suit.
(Would 62.6 grams make a difference? Do you see how that is arbitrary? The wanted to reduce propellant from a maximum of 125 Grams and just decided to cut it in half for no real reason. Damned Patriot Acts.)
BATF also declared APCP as "explosive" which it is not. Of course any substance that can be rapidlyoxidized is explosive when contained. But APCP does not explode in open air nor will it if it is attempted to be detonated by percussion like the High Explosives.
As for me I will continue to publish until I am caged...or dead. I no longer care.
Love the shot of the shadow of the smoke trail and rocket against the receding ground at about 4 minutes, thank you.
Thanks for watching and your comment. I am often surprised only a rocket model with cheap action camera on-board can catch interesting flight scenes. When in slow-motion sometimes looking realistic as real rocket flights, which scenes I like the most. From many published on-board camera real spacecraft take-off recordings I recommend e.g. the following:

Powerful rocket engines smoke trails on the background of beautiful Earth, blue skyline and deep black Universe. Always fascinating to me. Enjoy.
better than anything north korea can do lol 😂
usa will attack first anyway and we all know it...
Matyniov if that is the case it's called preemptive strike and it has been actually contemplated lately. So it could happen but they wouldn't launch any nuclear missle
Jose Castro Mmm, want to change your mind yet?
Jose Castro actually that is false. I'm no asian but north Korea can now build an ICBM capable of reaching all US mainlands
you laughed too early
Not only was it a lovely flight, but I have to say, that is one of the most beautiful looking rockets I think i've ever seen. Also, very futuristic looking.
how high did it go? thats crazy cool
The maximum height of the flight was not anything special - the apogee was at 675 m (2214 feet) above the ground. This rocket belongs to the class of high power rocket models but it is rather small rocket. The lift off mass is about 2.8 kg (6.17 lb) and length about 1.5 m (5 ft).
The most powerful rocket model I built so far is the following three stage rocket model:
th-cam.com/video/YOz-HTimVfs/w-d-xo.html
However it is also small rocket model regarding the other high power rocket models of the other rocket model enthusiasts.
I recommend you watch take-off and flight video of truly High power rocket model (it is not my rocket) - there you will see the darkness of space and the curve of the earth for sure:

@@pavlikpetr2010 Wow I've gone skydiving and it seemed like it went well over 2k feet.
Wow the onboard camera was so stable I thought it was a simulation at first. Very cool!
Where did you buy the kit? Or did you make it from scratch
Built from scratch as any other of my rocket models. I am not sure how many hours I spent building this rocket, maybe around 300 hours in rocket model workshop. But if not including the design and development time and provided there are perfect construction plans for every detail (so I need not often go trial and error) it could be probably much less. Real scale models (mock-up) of rockets often seen at some competitions take significantly more time to build - usually thousands of workshop hours. Rocket motors can be expensive but I use only cheap rocket motors ROS40 popular in Middle Europe for rocket models. Construction material purchase price is about 150 to 200 USD including wood, paint, glue, epoxy, electronic components, .... One on-board mini camera can be for about 100 to 200 USD.
But if you want to begin building and flying with rocket models you should probably start with simple single stage rockets. Multistage rocket models are very elaborate flying machines and if not designed and built properly and carefully they usually do not survive first test flight - and last but not least can also be dangerous.

At the end of the day, I can't blame Hamas or the People of Israel!!
I mean, the fight is gone for more than 2 generations!!
They will hate each other and none knows how it all started!!
Nadeem Najimdeen -2 generations?! More like 2 thousand generations!
That was very cool.. I really liked everything from the smoke charges to simulate the launch sequence to the multiple cameras that captured the stages and trajectory. I’m only now getting back into the hobby after 40 or so years from when I last built and launched model rockets. A childhood friend of mine was given a trunk load of engines (up to D-12), and when I was visiting him he couldn’t wait to share them by taking my girlfriend and I out to a local field to launch the kits with his kids... It brought back SO many childhood memories that I’m now building the original Estes Saturn V kit from the early 70’s that I found on EBay!
I’d love to learn more about the electronics used to get the multiple engines to ignite at the same time as well as those used to trip the parachutes and other stages... not to mention the gyros to keep the rocket pointed up. Incredible how far the hobby has grown in the 4 or so decades when I was building and launching them. Thanks again for sharing this video!
There is not any active on-board stabilizer system - only the passive stabilization by tail fins and correct position of the rocket centre of gravity..
The primary function of gyro-vertical is to initiate deployment of rocket recovery system in apogee. Another important flight safety function is emergency switch-off of all rocket engines ignition in 2nd (and 3rd stage for 3 stage rockets) and ejection of payload with on board batteries if the rocket axes is more than 50 degrees out of vertical. My rather simple gyro-vertical device as built at the moment is not able to control or stabilize rocket flight direction.
I am using only mechanical system of deployment just eliminating any ejection charge.
The booster is pushed out to the side by bamboo spring and hold in place by nylon fishing line. Booster separation is initiated by deceleration sensor which switches on simple electric circuit which heats up small resistance coil which in a fraction of second burns/cuts the binding nylon line. The nose cone is pushed out by small steel leaf spring located at the outer edge of the cone and hold in place by short pin protruding out of the inner edge of the nose cone into the hole in the rocket body tube. As soon as the booster turns out of the rocket body tube the pin runs out of the hole in the rocket body tube releasing the nose cone. The three small parachutes inside each booster are located just behind the nose cone and they are self-ejected during the booster rotation at the time of booster separation. maybe you can see it in more detailed view in slow motion video of launch of my two stage rocket with larger boosters: th-cam.com/video/-GX4bt3I0-A/w-d-xo.html
The second stage has the same separation initiation by heat-cutting nylon fishing line but it is pushed down from the third stage by styrofoam piston driven by rubber bands. When the piston inside the second stage starts moving up it also deploys cylinder container with the second stage parachute. The same principle is used for the third stage main parachute and payload deployment but it is initiated by signal from electro-mechanical gyro-vertical when the third stage hull axes reaches horizontal position at apogee. This system of deployment works fine for rather "small" and "slow" rocket models. It might not work right for any rocket model reaching supersonic speed of flight in case of need of parachute emergency ejection.
More technical details about the gyro-vertical and its function presentation is published at the end of another three stage rocket launch video:
th-cam.com/video/YOz-HTimVfs/w-d-xo.html
Interesting flight of the same rocket also here: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html
Another staging rocket model which can be of your interest:
th-cam.com/video/BleKydEyUTQ/w-d-xo.html
In this case I use active stabilization by mechanical gyro which is to prevent or reduce rocket spin - the main goal is to keep the on-board cameras video stable without disturbing spin. The mechanical gyro principle is almost identical to the function of Rolleron used earlier in military e.g. for Sidewinder missile spin elimination.
I recommend you get in touch with some of your local rocketry club or group of enthusiasts to get some ideas about advanced electronics used for e.g. dual deployment, staging and parachute ejection in case you would like to incorporate it in your rocket models. My rather simple home-built elektronics is difficult to duplicate without detailed plans and some experience and it is more or less just for inspiration. It is usually a lot of fun to participate in some of rocket model meets and gather launch field experience.
Welcome back in the world of rocketry and enjoy your rocket models.
@@pavlikpetr2010 I appreciate your reply, and am in awe of your modeling skills. Looking forward to more from you!
send it to N Korea just to mess with em lol.
I LOL'd so hard!
WTF? Lol!
That smoke before launch was Hollywood material. Awesome and the flight. Wow.
that would usually be referred to as a 2.5 stage design
Probably correct. Only 4 rocket engines are ignited at launch - 2 engines in each booster. After both boosters burnout and their separation the ignition of the next stage takes place.
No the .5 is only added for rockets that keep engines attached after they run out of fuel. The rocket was made of 3 groups that were detached by the end, it was indeed a 3 stage rocket.
Thanks for your comment and clarification of so-called .5 stage rocket.
My other rocket model HARPOON is 2.5 stage rocket - the second stage of HARPOON model has cluster of 4 rocket motors ignited in sequence in groups of two motors. After ejection of 1st stage the 2nd stage has ignition of 2 rocket motors and after their burnout they are not jettisoned and the last 2 rocket motors are ignited. The 2nd stage returns to earth on parachutes with all 4 burnout rocket motors: th-cam.com/video/kCLbxjvnDWE/w-d-xo.html

Beautiful parallel booster Rockets! I have not tried this myself, only two stage sounding Rocket using F-1 Engines. Highest altitude so far 1500 Meters but working on reaching higher. Great Job! Love it! Thank You!
Best video & demonstration of model rocketry that I have ever seen, period. I can only guess at the huge untold number of hours it must have taken to achieve this success! And, also one of the number of learning steps that accompanies such successes. Fantastic! I look forward to seeing where you've gone in 4 years since. Big thumbs up!
I am happy you like the video of my three stage rocket model launch several years ago. It was my first 3 stage rocket model and due to several necessary functional design development modifications it does not look too neat. However it is reliable rocket model but too ,,expensive" timewise to prepare for the launch and too sensitive to wind gusts during the flight.

Thank you for watching.
As a former rocketeer, I enjoyed seeing the flights and the group of rocketeers with their rockets too!
If you like a nice photo of the group of rocketeers during our annual meeting in 2015 is also here: th-cam.com/video/kCLbxjvnDWE/w-d-xo.html
Comment is in Czech but the pictures are international ... For you information there is unusual launch of my 2 & 1/2 stage model of rocket Harpoon during a rain shower. The second launch is the launch of 2 stage rocket Herkules - but the ignition of the second stage motors failed. Everything landed undamaged as emergency recovery system worked properly. Successful launch of 2 stage Herkules rocket model: th-cam.com/video/um7Ct-K27O8/w-d-xo.html
My latest 3 stage rocket ROSON from this year meeting of rocketeers: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
Thank you and enjoy.
wow outstanding video probably my favorite model rocket video ever. so smooth and high quality video
Thank you for watching and your comment.

Heya Petr!
Absolutely wonderful. Loved the pre-ignition smoke simulation, the booster drop(3 chutes each!), stage separation, apogee arc over, booster cam viewpoint and it was wonderful to see your fellow rocketeers at Klub Praha (go Sat 5 B!). Fantastic accomplishment. Thanks for the inspiration and keep up the great work.
Thank you for your high rating - I am pleased a lot you like the video. Hope you found some tips useful for your model rocketry or other activity.
If you like please have a look at my new and the latest three stage rocket flight. There is more interesting scene around the launch pad and not just farming fields: th-cam.com/video/YOz-HTimVfs/w-d-xo.html
If you like the boosters' separation - please have a look at my two stage rocket, where the booster separation is very smooth: th-cam.com/video/D66xKCXIUKA/w-d-xo.html
Nice video!
Late last week, God gave me a dream about 2 6 foot tall model rockets being assembled inside what looked like a high school gymnasium, and I remember telling someone I was with that it would really be cool if what they were doing really took off, and the could hire us to work with them. Be richly blessed!!!
A fantastic rocket! ! ! Ive never seen such a cool multi stage model ! Bravo 👏 👏
That is fantastic!! Wernher Von Braun would be PROUD of you!
In my young model rocket days in Phoenix, in my wildest dreams....well, you're living the dream!! How awesome is that!!
👏🏽👏🏽👏🏽 Best launch, flight & recordings I've ever seen. Especially liked the ignition sequence, so authentic. Great job! 👍🏽🙂💪🏽👽🖖🏽😎🤘🏼🌎✌🏽️
I am glad you like it. I am always trying a small model rocket looks authentic as the real big rocket.

Very special is model rocket of Little Joe - NASA did not use any advanced on-board camera - therefore the recording from on-board model rocket cameras are quite exceptional and rare: th-cam.com/video/BleKydEyUTQ/w-d-xo.html
Looks like a lot of fun. If only I didn't have too many hobbies already. Thanks for the video. I will look for more.
a lot of support for these older kids who never grew up, now I don't feel so lonely
This is by far the absolute coolest model rocket I have seen!
Apollo Missions: The Home Version
The ignitions are so perfectly timed! and I love the first stage parachute.. Amazing design and great stable mounting of the camera..
What a cool video! Started up with rockets and I ended up with model airplanes. Thanks for sharing.
I started with airplanes when I was a small boy. Now of senior age I'm only in the rocket models but I think I will end up with airplanes finally - because the rockets are often too much thrilling and you are too often close to some kind of flight disaster.

That was freakin' awsome, Petr. Well done. You rawk.
That is seriously good footage. Excellent. All I’d suggest is to give us more time on the still images so we can read the captions and take everything in. But wow, superb!! Thanks for posting!
I am glad you like it. You are right - more time on the still images would be better.

Very very cool, best high powered model rocket show I’ve ever seen.⭐️⭐️⭐️⭐️⭐️
Fantastic job, both on the rocket, and the detailed video! I'd want a full speed take at the end, though!
Thank you for your comment. In some of my rocket launch videos I published full speed flight recordings just for fun, but I am afraid it is too fast to watch. For example have a look at the launch of three stage rocket ROSON:
th-cam.com/video/YOz-HTimVfs/w-d-xo.html
from about T 3:40 there is launch in original speed of the recording: th-cam.com/video/YOz-HTimVfs/w-d-xo.html?t=220
I prefer slow-mo because it looks more realistic. And to be as realistic as possible is the goal of most of rocket models.
Another launch where is also included full speed recording is the following video of the launch of 2 stage rocket HERKULES: th-cam.com/video/D66xKCXIUKA/w-d-xo.html
or here: th-cam.com/video/um7Ct-K27O8/w-d-xo.html
Glad i found this. You sir, are quite the rocketeer! Bravo.
Thank you.
If you like here is my latest 3-stage model rocket DELTA IV HEAVY Parker Solar Probe: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html
But the most successful with many perfect repeat launches long term is my 3-stage rocket I designed and built shortly after my first 3-stage rocket: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html
The most difficult to achieve are these moments of the launch - recorded air start of the 3rd stage cluster of 2 rocket motors: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html?t=38
Excellent control systems on board. You have fault tolerance, very nice touch.
Nice rotation totally flawless! Great camera views and the fruit of what had to be many hours of work. In my day it was Estes and Centuri. Super Sweeet!

Thank you for watching.
That was beautiful and masterfully done. Great video quality. A true rocketeer.
*THAT WAS EXCITING AND YOU GUYS ARE WELL ON YOUR WAY TO BECOMING ROCKETEERS-MEN!!* *;-)*
Love that clear blue sky. And @ 6:30 in video, That's an impressive set of hardware there
Great job! You should be proud of that launch and the staging, just perfect. And the pre-launch smoke was a really nice addition!
In 1974 at age 14 we filled the rocket with home made black powder, glued the top on, and launched the rocket. 👍🏻 Brilliant!
Very nice job of stabilized flight and engine ignition in staging. Especially with the large gap or space between the stages. I've never seen that before. Very Cool! Thanks
Congratulations! This is a beautiful rocket project and a wonderful video. Very well done!!
What a fantastic video. You guys did a great job on both rocket and the film. Had a moment of déjà vu and could almost smell the dope. LOL used to use that stuff a lot in the grade school hobby class. Makes me want to go out and build another rocket.
It's nice to see so many rocket enthusiasts share in such widespread success. Perhaps, if NASA sought your input....they'd be able to finally launch the issue plagued and often delayed STS. Well done!
Thank you for your comment. It was my first three stage model rocket. And as apparent overall design beauty suffered from necessary addition of more rocket motors to get the rocket takeoff more reliable and stable and also adding some smoke charges to do the ,,show" for audience.
If you like here is my last year launch of model rocket DELTA IV HEAVY built as three stage model: th-cam.com/video/DUgpKB_YXi4/w-d-xo.html
Probably worth seeing is also another of my previous launches of three stage rockets: th-cam.com/video/JMq2dW_V4uw/w-d-xo.html
Soooo....you guys are a bit serious about these things, huh? LOL...GREAT job, awesome footage. I spent a lot of time with model rockets when I was a teen, but the best one could hope for then was a blurry and grainy 110 film snap at apogee, this stuff amazes me. Post more! Thanks!

You need funding and you can go well into space. You earned a subscriber. I dream of building a rocket similar. You need to be a teacher for rockets, unless you already are. Your designs are very inspiring.
stage 3 model rocket just on the outskirts of outer space well done I congratulate you sincerely TCB Elvis Presley never missed a launch
Very nice job, it all worked flawlessly. Congratulations. I built rockets as a teenager, but not as complicated as this. Very enjoyable. Thanks for the video.

Thanks for sharing your work. It's a lot of fun to watch.
Outstanding!Mr Pavlik, take a bow
Very nice camera work. The flight sequences were spectacular!
Thank you very much - usually not easy to get everything working properly and as intended.

(Omg this is in Czech republic! Great rocket! I'm also from Czech republic.)
I live watching these launches and all the separations and parachutes , absolutely amazing to watch and I just wish I could have seen it in person
In person experience is irreplaceable. But on the video you often catch unusual views which are often missed when just watching from the ground.

I saw the curvature of the earth... and the sky was a bit darker blue too. Great video
Took just little power more to reach orbit. Great video!!!!!
Gorgeous! Stable flight, almost zero spin!
Sometimes I am surprised there is no spin at all - in case of good luck when all clustered rocket motors have the same performance and almost perfect alignment of nozzle axes:

Or only a little spin:
