- In this video I attempt to install mini spy cameras inside of my homemade 3D printed CO2 rockets. These rockets snugly hold 12 gram CO2 cartridges that are normally used in airsoft and paintball guns. I also end up putting the cameras inside of some model rockets! If you haven't seen my previous video on these CO2 rockets make sure you go and watch that as well! The printed used in this video was the Creality CR-10.

Three ideas:
1: Shorter launch tube with larger diameter. Fins with larger diameter then the rocket, and the rocket stabilized in the tube like a SABOT style projectile. Se wikipedia.
2: More fins. A high number of small fins should increase the effective area causing drag. Having 12 fins should equal having 4 fins with 3 times the area, but the rocket body will be making a hole in the air, so the drag increase would be much less. More like 1,5 to 2 times that of having 4 fins.
3: To increase flight time/height; heat the CO2 cartridge to about 40 degrees before launch. Can be done by storing the rockets in a heating blanket before launch.
Please replay to the comment for more ideas.
a larger tube will lower the pressure inside,I think,the rocket needs to travel a longer distance in the tube,just like a rifle......
But the friction of the tube will also slow down the rocket. If you look at real concepts for rocket launches it is only at the start there is any real advantage to have it in a tube, and if the rocket is stable in construction (i.e. placement of center gravity and center pressure is correct) it doesn't need the tube to stabilize. This can bee seen in any full size rocket as well as in something as simple as water rockets.
One option could even be to fill the bottom of the tube with water to make a better seal against the rocket to increase the pressure right after the start. This has been proposed for many rocket systems like the Space X BFR, and is actively in use with submarine launches.
Another option can be to have a small water tank that the CO2 cartridge is connected to, so that for the first half meter of flight it is actually propelling it self on a stream of water. this would greatly increase the acceleration in the start, but would also make bursting the CO2 seal hard...
Another way to increase the area of the fins without making the rocket have a larger diameter would be to encapsulate them with a ring, like a duct on a propeller. This could connect to all four fins, and could even have a "ribbed" structure to pull even more air into it. All without increasing the total diameter of the rocket.
watch the vid of Richard hammond here on YT on propulsion threw a tube with an air compressor,the tighter the projectile in the tube the longer it goes when fired.
it's on RH connections with the building of the A3880.
I think the pvc pipe wobbling back a forth also has something to do with the rockets not flying straight :)
Its way late to comment, but its doesn't fly straight because its not balanced. If it was spin stabilized (rotate about the Z axis in flight) it would fly true
that wat i though so still looking at the wind and the weight it also a bit disadvantage as moving up to air the wind speed is increasing so that we dont have enough edge which can cut through it !!!!!!!!!!!!!!!!!!!!
(lets hope you got it)
me too i saw the guy's hand move forward a little when the black rocket end was in but the head was out
testtestjimmy if it was spin stabilized it would be useless for video
Tary1233 maybe a brass or metal pipe could do better

The stability could be improved by stiffening you launch tube. As it is the rocket causes the barrel to whip around and will flick it off to the side. Three dowels taped around the perimeter would probably do the trick though more would be better.
Do you sell dowels for a living? I would use one.
@@no-name420 Walmart has them for cheap. Just make sure they are straight. Some are warped a bit.
very cool! I just got my pen cam in the mail. Not sure why I ordered it but this project gives me some ideas!

Space engineers: micro
Thank you for completing a satisfying video, despite all the setbacks!
Awesome!! Love that you are working the trial-and-error process and making improvements each time. For a more stable launch, try cutting 50cm off the launch tube. It appears that the PVC tube bends during launch causing friction to the rocket and an unstable trajectory upon launch? A shorter tube may correct that. Try different lengths. Keep up the great work, and I can't wait to see what you come up with next!!
FYI spring loaded fins would work or a smaller rocket with a discarding sabot either of these would allow the rockets to fly straight. Also you should make a video about redesigning these rockets as torpedoes that would be awesome.
Really nice work, man! And congratulations to the winners! Specially to Creating Creations! :D
MC's Creations Thanks:)
Put a whistle on them now
hmm remembers me of 1942 no no Germany bomb …
I love brief construction montages. Bring it on!
I would recomened peter stripols javlen roocket series to figue out foldable fins
randomness yay - same idea. But I had suggested to take the RPG-7 propelled grenade and make a less deadly copy :-) Foldable fins rock
Thanks for the keychain.
I use too fly model rockets when I was a kid, I use to test them for stabilization by tying a string around the CG point ans then spinning around
You can actually learn an amazing amount about rocket/fluid mechanics through tests like these
I feel like your launch tube thing needs to be more vertical, more stable, more rigid, for vertical and more lubricated
Loved this video, and the co2 rockets in general. I do notice in the slow mo's that you get a bit of whip in the end of the launch tube...have you considered using Schedule-80 pipe (the black stuff), it's meant for high pressure, therefore much more rigid that then schedule 40 (white). Just a thought, keep up the great videos
2 stage rocket, where 2nd stage pops out spring loaded fins hidden in spiral slots? how do you trigger the 2nd stage and drop off the first stage?
The feeling when you cant find your model rocket...
Ive been there with my mini quads, I have already lost 3 and I have somehow lost my model airplane which shouldnt be too hard to find but its just gone.
This video is definetly worth a sub, your content is great
I avoid the 'losing' feeling by just gluing fins onto my rocket engines, and if I'm feeling real crafty I toss a nose cone on the engine.
All you need to do is increase the amount of drag on the bottom of the rocket. Try making a tower instead of using a tube, you can still use your current device to launch it just make it shorter with slots for the fins. If you have questions reply and I can help.
that phill bot the only issue I'd see with that is that the expanding gasses create pressure, which in turn gives the rocket thrust. But, like a bullet, this only works in a chamber like the tube. If he had a way to provide more propulsion than I think the slotted launcher would be a great idea
I think you're on the right track with the drag at the back. Perhaps extending the straight body of the rocket down over the aft taper a little to form a kind of skirt.
Hopefully YT won't mangle this ASCII-art...

Should let you keep diameter the same while adding some aerodynamic drag and allowing for the existing fins to stay.
The open slot in the bottom for the trigger negates that.
Just completely remove the pvc pipe and use a slightly modified(like a 1 inch hole drilled into the base of the launch pad where you put the nail spring thing) version if the estes model rocket launch pad.
P.s. 3d print a little tube to align the rocket with the launch pad.
larger tube to permit bigger fins, ribs atop to keep it aligned and if a seal is needed to capture the pressure as well as using the thrust. of the gases, a semi-disposable disk or cone that falls away when the pressure in tube decreases. I didn't see the earlier videos so I don'tknow if you used exact tube size to contain pressure
Simple stability testing: With everything loaded (engine and payload) make a loop on a string and put it around the rocket body. Move the loop until the rocket will balance horizontally, then tape the loop so it can't move. No you can spin the rocket around in a circle on the string, if the nose cone stays forward you have a stable design, if not you need bigger fins or more weight towards the nose. It's what the rocket does while in the air that matters most.
you could make triple spring loaded fins on a hinge to make the rockets fly, it can probably fit, considering you can easily 3d print a small mechanism.
But they would scrape on the barrel
Fred Frod if you make a spring loaded set of fins that have a weak spring in it, then it won’t be a big difference compared to what occurred now. Only thing you have to do is making a pin that will lock the fins in place when it is fully extended. That way it has almost no drag, but it can extend those wings to a bigger size
The rocket itself already "scrapes" on the barrel. The added drag would be minimal.
Launch Co2 rocketa on summer time. It flies much faster.
heating up cylinder a bit might help without melting plastic.
seems like winter the air would be dryer with less water humidity, and therefor have less resistence, so rocket should fly higher
@@SystemsPlanet
Dry summer day should be best. The temperature of the air and the plastics on the rocket matters since the CO2 container itself will rapidly become colder due to the decompression.
Launch tube is too long a wobbly. Stabilize the tube and set the launch like a mortar shell design fins so the fold around the fuselage. Once rocket eject from tube fins will fold out with help from rubber bands, tensioned bamboo, springs, or even air drag shape. Liked the ideas.
I think use a larger diam. tube with a sabot for the rocket body, the sabot would need to be as light as posable, the larger tube would give room for wider fins?
Cutest dog!!
A bit late in coming, but as an alternate design suggestion, try making a CO2 spigot mortar.
For anyone who hasn't heard of a spigot mortar, look up the British WWII PIAT (stands for Projector, Infantry, Anti-Tank). The projectile goes over the firing tube, not inside, so you don't have to create such a small payload.
Way cool! We built Co2 dragsters in high school for a wood shop / science project. 100' of deep sea fishing line taunt between two points and supped up pinewood derby cars with eyelets on the bottom. Same idea and it was loads of fun for a bunch of seventh graders. We had a few mishaps at the starting line but I still remember it like it was yesterday. Seen the description in the video title and had to take a look. Thanks for the video. Great job!
I'm currently learning the art of 3D printing! So far, that's been a learning experience!
You should try putting a sabot on the rocket and launching it from a larger diameter tube. That way your fins can be significantly larger than the outer diameter of the rocket.
I have never built a rocket before. Just designed black powder rifles. lol
this
Lots of good solutions or suggestions in the comments.
It’s funny how people are idiots and usually this only gets worse as you get more people involved…and yet in the YT comments sections, which often the pinnacle of human stupidity and mob mentality run amok, and yet… and yet…
Add folding fins to it, Like rocket grenades or anti tank rocket launcher head's have.
Nice vid I have never seen a experiment like this I have wanted to make a CO2 rockets but I don't have the stuff to make it but awesome vid.!!!!
The young Sheldon has grown and has become a rocket scientist. Who would think that! I´m glad!
Could use something like a sabot for the fins and use a thicker tube
you rockets are really cool but now you need to build a sturdy launch pad and a more accurate pin for your puncture.
How does your anet a8 work? I cant yer my to level the same way and one side doesnt twist the same as the other
your project just reminded me of the movie "October Sky". Enjoyed a lot. Thanks
Creative idea well executed
Thank you!
I can think of a couple of fixes that would require varying levels of effort. The easiest way would be to not print the fins, and simply glue fletching to the side of the rocket then wrap it in wax paper to reduce the friction. Once the rocket exits the tube the fins will unfurl and the paper will just float off to the side. The other concept is to do away with the launch tube altogether, and design a launch mount with more standard model rocket features.
Have you tried making the rocket spin as it is leaving the tube, to stabilise it, i.e make the fins slightly curved at the ends
when I was a kid we had a similar rocket with a camera and parachute already built in. That was probably one of the coolest toys I ever got to play with or, more accurately, watch my older brother play with.
Use mouse traps for the spring pop out fins
Cant you try making he fins spiral a little bit so its more accurate? Ofcourse thats not good with camera but it sure makes a beautiful launch :)
Came here to suggest that. NASA flies sounding rockets ("Super Loki") that spin to give them more stability.
But spin when you are trying to take video is generally a bad thing. Yes the rocket would be more stable in flight but the video would just be spinning round and round.
Nice work. Something I couldn't quite finish 40 yrs ago. Fuel was a problem then. Had to manufacture it from matchstick heads. Greetings from New Zealand 🇳🇿
Powdered zinc and sulfer we used to fire them in a homemade bazooka..used those Estes ignitor
a sabot may work or some sort of rifeling on the rocket or fins to make it rotate
So for the fins, why not have 4 fins that are spring loaded? When placing the rocket in the tube, manually press the fins in, and slide into the tube. Then, when it gets pierced and exits the tube, as soon as it exits, the fins will spring out and have more stable flight?
SilentAirGunner but it might slow it down
Still better than anything North Korea has at the moment lol
Fordman 1991 incorrect but if it brings some people comfort then sure.
Nope. They actually launched a rocket that probably went further than any amateur builds.
/r/wooosh
The North Koreans might surprise you on their tech and ability to send a heavy missle. While your comment was funny,....way off the mark.
@@mihirpatil8843 their rockets are decently advanced but definitely not as good as any structured country like the USA.
The USB cam is on a flexible cable ...you could poke it out the side and point it down to get a cool shot. Just print a nacelle on both sides to balance drag.
Cool projects!
It's been a really long since I looked at model rocket design, but I recall reading there is no benefit for pointed nosecones at subsonic speeds. I'll have to go back and look at the CO2 rocket video, but do you see any difference with a shorter launch tube?
You should make the fins riffled so it has a steady spin in order to fly straight high and stable
you want it to spin less. you won't get good videos if it's spinning a lot.
who gives a fuck about videos, if you can't even get your rocket stabilized?
Fins are designed to mage the rocket spin, not to get rid of the spin. Spin is a good thing for rockets and projectiles, that's why you have rifled barrel guns. Also that shitty camera won't make any good footage ever, there is no point of fucking up the whole rocket for it
Actually, fins are designed to stop it from spinning and to move its center of pressure behind its center of mass(especially with unguided rockets)
Fins create drag. Spin created by fins creates more drag.
@@MrDoboz the point of the video is too get good footage dickhead
try the cam on front of the rocket
This is awesome! All that hard work, but you still had fun and enjoyed it even though there were many failures. Keep strong! Have fun :)
Awesome guys, love the style, looks such good fun
Some apple farmer is gunna be so confused.
North Korea missile testing
Use 3 thin wolires that pop out the length of your rockets they will help support the rockets gyro stability like using your arms when u spin to slow u down
use a compliant material for the fins. Wire/leaf spring and fabric? Springs into shape once deployed.
Just got recommended this vid. You want good footage you should just drop the rocket idea and make a nice, slow hot air balloon with a 3d printed "basket" or do what everybody else does and use a drone. If you are going to stick with the rocket idea you need much larger fins and then design a different launcher. I did tons of this stuff when I was kid, usually through boy scouts. Ironically for your project the best flying rockets usually have the tail fins all ever so slightly pointed in one direction so the rocket flies with a spin like a bullet/football. Also consider a flasher and launching near dusk so you can find it afterwards.
Cut three slots in the pvc tube so longer fins could work
Alpha_wolf 1987 you wouldn't have as much pressure to the rocket
You wouldn't have much of a launch
I love that you don't give up!
have you tried incorporating the nail in to the rocket itself so you just drop it in to the tube and it will self puncture and pop the nail out?
Put a Parachute on it
when you have all the technology and none of the knowledge needed to build a rocket...
I had this idea the other day, and I gotta say, great idea!
What cad did you use for the usb drive camera?
Simply cut lines in the tube and add bigger fins to fit between the lines :P
Mr. unitato the pvc would become too flimsy because it is so thin and long, the fins would catch against the inconsistent gradient of the cuts, the gradient being caused by warping in the pvc
P.A.N. what about a square tube?
I think a square tube with the fins aligned in the corners and a sabot would work well
Interesting idea thanks!
Use pen camera, USB is much lower quality, maybe try to make wings wider than rocket, like this air go next to them so they don't do anything... i think :)
Take some more rugged pipe and cut holes for wings to it, i noticed that on slow motion pipe is pretty soft and it bent on start.
Oh and mount cam on top, not on side, it will rotate much slower and image won't be so blurred
Please don't drill in objects you're holding in your hands. Younger viewers might get inspired.
Write your phone number on your rockets, that way, if it gets away from you, you might a phone call when someone else finds it.
lhl2500 So he can get sued for broken winshields and Windows?
Bruh...
Well, if he broke something, wouldn't it be right to actually pay for damages?
Don't give your 10yo a drill...
you didnt have a drill when you were 10?
Impressed with your dedication. You kept trying which finally paid off!
What if you put them in a more rigid straighter pipe like metal ones AND/OR spray the inside of the tube with silicone to slide nicer ?
*Write a "return to" with an address or number on it, I'm sure someone will find it* 😁😁
if it hits a window or smthin or a person or idk then they will know who did it
Tokyodriftbabys
That wold be funny
That rocket had a parachute. It is unlikely that it would damage anything on landing. Even if they go ballistic, they are not capable of doing much damage. They just don't have the weight or energy to break glass. The only windows that would be at risk from a vertical launch would be windshields and they are extremely strong safety glass.
ah ok but it was just an idea
dstnlockwood
Trudeau bans CO2 rockets ;)
i hate trudeau
Hey great video We have a gmax printer and I was wondering what software you are using to design in we need some help in that dept thanks much great work !
I saw your video and tried some of my own rockets. I didn't think to capture footage, but I decided to use a shorter tube. MUCH shorter, but added extended fins to the rocket. The extended fins made it so I did not need the longer length of pipe. My total PVC pipe length is only 14". What I did at the top was cut channels 8" down into the pipe, like a cross [+] if looking down the pipe. The channels are about 1/4" wide. I made my rockets with fins that extended about 20mm from the body. The rocket stabilizes amazingly. I didn't do the camera mod, but did use about 1oz. of clay, as mock weight, and it worked quite well. I did a generic 35-degree angle on the fins, but I'm sure you can try any design, shape, or angle you feel is necessary. Only piece of recommendation is make sure you sand the channels in the PVC pipe, WELL, and maybe round the corners a little.

I really love your never give up attitude
Retractable spring loaded fins, will solve your stability issue and use multiple stabilizing jets similar to rpg7 rocket
Great idea!
what about using a mechanical broadhead type design/parts to make it expand after exit or use a weight to make it release after acceleration
What software you use for design the 3d printing project?
It most lil won't help with camera footage, but setting the rocket fins on an angle to the rocket spirals on its ascent would help keep rockets stable during flight :)
Could u not use a wider launch tube which would in turn leave enough room for top fins as well as bottom fins
I launched many model rockets as a kid. The simpler the rocket the better and more stable they go. You could also go with multiple stage rockets. There used to be a model rocket called an egg launcher. It had a three engine cluster. Three size C-6-7 engines. The difficulty was getting all three engines fire at the same time. You could also buy a kit with an assortment of tubing, nose cones, balsa wood to create your own designs.
Foldable fins which deploy as soon they are out of the tube?
A couple of thoughts:
1)The Firing Pin. Have it secured in a bearing, much like a firearm does. The Hammer is spring loaded weight, not the firing pin. That way it strikes where it suppose to every time.
1a) Sharpen the tip of the nail with more insight. If the rocket fins deliver a rotation to the missile, cut the firing pin so that the escaping exhaust is channeled into a slight spiral towards the fin direction. However, any rotation won't make for a very good camera view, so bag the fin idea entirely, . .
2) And use the old fashion STICK method. Cut a thin groove along the launch tube for the balance stick to slide up when fired. The Stick shouldn't be heavy, for it only acts like a drag rudder. (Think "Bamboo". . ) If it were a hollow tube, it would be lighter and would work even better, being that it would act like a pseudo "fin" as well. . . But, it still needs to be long and ridged enough to stabilize the missile against the air flow to keep the pointy side up and the stinky side down..
Oh yeah. . . Reinforce the nose cone. In fact, make it a rounded blunt. Your rockets don't achieve super sonic speed, so in all reality, a pointed nose cone will induce more drag, where as the rounded aspect is the way air naturally flows traveling at a sub sonic speed. And always remember, the way it went up, will be same the way it comes back down. Pointy end first.
Problem solved?
This hard work deserves at least 10M views
Neat stuff! Years ago (read, "pre-digital"), Estes marketed the Cineroc. It was fitted with a miniature movie film camera. All cool and stuff, but I don't recall seeing any flight films, so I don't know how well it worked. Really enjoyed this one, thanks!
your vid made my day :) thanks
pop out fins sound amazing if you can do that. I would recommend making slits in the pvc along where the fins would go.
If you can’t add rifling can you print slightly spiral fins?
When you launch make sure the tube isn’t bent or flopping about. Maybe glue some wood to it
Any probable way to create fins that collapse down and then unfold once it leaves the tube? Could be spring loaded. Idk. Just a thought. That would give the rockets a higher fin profile, thus improved stability.
I believe you need a longer thinner tube for the co2 to pass through thus getting more thrust, and then it does not matter if the firing pin is not hitting straight. (maby)
Do you mind sharing your recent design STL's I only saw your older ones online! I debating on trying these for my science class!
Spring loaded fold out fins? Works for guided smoothbore artillery shells...
drill some holes in the pvc near the top to vent excess pressure that kicks the tail at exit, this works for air cannons
For the co2 rocket extending fins, you could find small springs that may work in dollar store cap guns.
Great attention to detail and explanation of everything! I love your video style!
I wonder if you could make design using some water that the co2 pushes out first to give it more thrust, I think. And maybe a small streamer on the end to help stabilize it.
awsome bro try glueing on arrow fins or veins as they are bigger and also flexible so will go down the launch tube
A few things I noticed immediately that you eventually gathered and/or maybe never did:
1. The nail was an extremely ineffective way to launch due to it being responsible for things that couldn't be reproduced again and again for testing, good or bad.
2. The launch system wad a poor choice as it flexed, wobbled, bowed, etc. This absolutely had a further impact in stability and events that can not be reproduced again and again for testing.
3. The higher the weight the less stable a rocket is with a single nozzle at the bottom (regardless of fuel used). It's like asking someone on stilts to be more stable than someone crawling.
4. The 3d printing itself likely led to instability.
Overall, very neat video and I'm glad you finally got it to work. In the future, include a small piece of rolled-up paper with your details in case you lose the rocket again.
