Wow! That was FAST! Next stop: THE MOON! :D
Yep
Via the centre of the Earth! ;) Seriously though, that looks like a propper handful, is it even human controllable?
*Insert evil laugh here*
Yeah man 💥
look at the channel BPS Space. there the guy does a controlled vertical takeoff. quickly decelerate the rocket after a vertical force impulse. if it is at the height of radio coverage, you can make retractable wings and catch gliding. or glide with a parachute from the servo.
ps. this is calculated from the power mass of the rocket, which means you need to calculate the strength of the initial charge on the stand with weights.
It's an honor to have my name hit the ground at 160mph!
Haha! Thanks as always for the support Peter!
Why would you spoil it :(
pov you accidentally saw this before the video started
I did
@@SZ_DARKK pov yes
implementing automated flight control is probably the best thing you could do for the power and forces on the plane
Getting the PID right with the airframe flexing all over is going to be almost impossible. The aircraft averaged almost 14 g when it hit top speed (165 mph in 0.54 seconds). Peak loading could be double that.
@@otm646 I'm not sure if he used a gyro but if not, he should definitly get one mounted.
@@otm646 that's probably an argument against any control surfaces.
Or perhaps an argument for fiberglass reinforced surfaces filletted directly onto the carbon fiber core.
PLS DO! He would help your channel AND your avionics!
Maybe turn the sensitivity WAY down?
Your videos are always a treat, James, no matter the outcome! Fast rocket-y things are very hard to control :/
rocket go fwooosh
Thanks Joe. Success tastes sweeter after blood, sweat and tears - as I'm sure you appreciate!
Absolutly!
BPS I’m a fan of u also
WOW BPS SPACE COMMENTED
Point it up more, stiffen up the control surfaces, get it flying nicely as a glider first, think about a roll gyro, nice work and keep it up!
A gyro would definitely be a good idea here
yes he should not rely on his reflexes to control the rocket!
@@hawkfpv4950 if it has positive stability in theory it should be able to fly hands off during the boost phase.
also try not to crash :)
I agree and think that the launch angle should be at least 60 degrees. You want some altitude before gliding for both safety and having enough time to get it under control before it can hit the ground.
"Controlled into the ground" is a great phrase!
In aviation they say "CFIT" - "Controlled Flight Into Terrain"
@@matthewforan6397 Its one of the primary killers of pilots in Alaska.
"high powered rocket planes are hard to fly".... Mate i'm not sure we learned that today, i thought we had found that out long ago!
Hey it’s a start and most of it survived!! If you need a hand getting some controls on that BEAST feel free to shoot us a message ;)
9:27 was the best part because the fire coming from the igniter looked so cool
There's a reason why, "rocket science" is a euphemism for something difficult.
Difficult, but always spectacular
Rocket science is easy, rocket engineering is hard
Regardless of the “failure,” that was still VERY COOL. Thank you for taking us on your journey!
And that Land Rover is AWESOME!
Thanks Dan!
I think you owe Mike a pint! Sterling support!
Poor bloke had to wait until after the sponsor for a "Thank You!".
Have you considered putting a flight stabiliser or flight controller on board? You're getting up near the speeds where a human can't react in time doing it line of sight - maybe a computer could help?
Would the aurora board from flite test work for something like this?
@@lukedavid8099 I would think any FC would work. You could prob even use an old Naze +iNav in a pinch. Even an old board is going to be faster than a human on the sticks.
@@lukedavid8099 I have the Aurora, it's a pretty amazing board, but it's main function is to smooth things out, so you can fly smaller planes and they feel like larger planes. Definitely get one if you get a chance. I've got mine on an overpowered STOL cub. Everyone who flies it is amazed at how easy it is to control. It smooths everything out but it doesn't feel like a typical stabilized controller would. It will still let you crash it into the ground though, so it's different than a standard fc.
@@austntexan darn it man I wasn't sure if I should get one or not but you might have pushed me over the edge lol
@@lukedavid8099 i really like the safe system from the apprentice.
I have a umx habu and it's really fun. It helps me with cross wind and such.
Also nice to have the panic button lol.
Yes, what a great flight compliments!
A shifting mass in the fuselage would be an interesting solution to the rapid change in the CG from the rocket burning !
im 15 and i find most videos boring but i truly love watching your videos and they inspire me a whole lot thank you
You know it's a solid test flight when you take your aircraft home in a bin bag. I've done 150mph under FPV so I'm really routing for you to nail this cos it's one hell of an experience when you're under the hood. One big tip that will be handy down the line is to swap out that rubber duckie antenna on your goggles for something better. It will really help you get the most out of that little 25mw Vtx.
I used to this as my job ( I was missile programming engineer) and have a couple of pointers. But your launcher at a 45 degree angle. It gives you a little better chance to gain some altitude and time to recover from any mishaps. Also it takes some of the initial thrust and converts it to height instead of speed so it put less stress on the wings and controls. Putting the wing in the middle will make it more stable, the wing on the bottom is going want to flip it over. Or put the wings higher and a little angle up to give some inherent stability, otherwise put a gyro on it to try to keep it level. You might also consider replacing front canard with fully moving canards as elevons rather than flaps.
Last suggestion was my same idea
Everyone’s saying flight controller: dRehmFlight is waiting for you James ;)
But seriously, I think you found out the hard way that canards can be inherently destabilizing. If the vehicle pitches down, the canards in front of the cg will force the nose down more. On the other hand, a rear vertical surface will cause the nose to pitch back up. Next iteration I say: ditch the canards no matter how cool they look
Completely agree Nicholas! I’m think along the lines of a simple delta with a full composite construction - re: drehmFlight - would love to give that a try!
@@Project-Air Awesome, good luck!
11:25 "oh look, there is a battery in the tree" ....that really got me xD
Congrats on personal speed record. Thank you for your videos!
Something I remember from flying gliders, if you catch a stall, dive until you have enough speed to recover, otherwise turbulence will just keep building on the wings. Not saying this is what happened on the first flight, but it looks a slight bit like it.
Thanks for making such amazing videos. Love your content. Cheers!
Wow that was exciting ! I think it's better to aim the ramp higher so you have more altitude and time to control the aircraft. You could put some electric motors to take off : it would make you comfortable with the controls and allow you to get up to much higher speeds since rocket motors aren't very efficient at taking off. Another idea : paint your underside black so you know if you're upside down.
Love the fact that you take failures as a learning event. Well done.
That was great. Having the cameras and seeing the deflection on the control surfaces looks like it’s been really valuable. Looks like it pull loads of g before it terminated its flight. Can’t wait to see the next one. Do - Review - Apply.
He could probably approximately calculate the g's during that turn from data he has for this flight if he wanted to. Was pretty tight corner
I love the warts and all style of your videos, we're on a real journey with u, cant wait for the next vid!
Awesome flight! Congratulations! Also great to see your operator number in use :)
This kind of innovation is the future of engineering in the UK - keep up the great work.
rule#1 keep both hands on the sticks at all time and hold on for dear life.....very impressive young Sir
Yes yes yes bro! 🙌 I truly enjoy your way of experimenting and testing. It is how all the greats have done it! Great video mate!
That was fun! I did expect the big version to be launched more vertically, similar in fashion to the test model.
That engine is wild ! Beautiful flame !!
Pro tip for the barbed wire fence, pull up on the middle line and step on the bottom before you go through it.
Enjoyed the video series, subscribed.
True experimentation, loved it.
That was awesome James I enjoyed that keep up the good work
just the wicked flame coming out of the plane
Now I want to change the propulsion of my flying wing back to rocket.
Haha, nice first flight! Can’t wait for V2!!!
Keep up the work ! As discussed earlier , maybe establishing a glide and adding increasingly sophisticated flight computers makes sense . Just for starters , getting roll under control .
Wow! Awesome flight man!
Yet another incredible video from project air 👍👍👍👍
Using the Canard as a flap is nice! What I do is move the battery rearwards on a stepper-motor during the rocket-burn to keep the CG from wandering. Long-burn rocketmotors help here.
Fly it like the Space Shuttle. Vertical launch, horizontal landing. Altitude is your friend, giving you time to stabilise the return flight.
the sound was amazing great job
the battery dangling from the barbwire fence.... looked like it hang itself
i lost it...
🤣🤣🤣🤣🤣🤣
I hope you post the video more often.It is really good to watch.❤
They take a while to make! Although I'm now documenting larger projects in multiple parts - so they will be more frequent :)
It wouldn't be a proper testflight without some damages.
Keep up the great work
Really made my day with the shoutout, as always great and inspiring video. Keep it up 🔥
A bigger Field?
Looks like the whole place is one Big Giant Field!!!
Very impressive! Many airliners (esp. A320) reduce the control surface gains in proportion to the square of airspeed - you could start with just low rates for powered flight then higher rate for landing.
I absolutely love your videos
when the germans flew the ME 163 B in WW2 they would take off almost vertically to gain as much altitude as possible. maybe you could look into some of their designs? side note for those that don't know about the plane, its called the Messerschmitt ME 163 "Komet" . it was a liquid fuel based rocket interceptor that was made to defend german bases and strongholds. its engine was a catalyst based rocked that was run off of "C stoff" and "T stoff" which was super concentrated hydrogen peroxide as an oxidizer. this plane was recorded to go over 621 mph in level flight and had an unrecorded speed of over 700 mph.
for the canards you might want to use a single CF rod to mount them and it can also be a hinge. Use a servo made for bigger gas planes so it can handle more force.
Great content, wonderful work!
Brilliant, Don't give up on it that was kewl!.
Kudos from across the pond....u are a smart kid, always experimenting and overcoming.....i see you going places👍
Holy crap you mean the weather was actually agreeable? 😂 Great upload buddy!
I loved the locals.
I like the ad timer on the bottom
7:40 WOW RACING CAR!!!
Nice Land Rover!
Great job 👏🏻
great video! most enjoyable! love the planning, implementation and execution. i’m sure that Robert Goddard himself mumbled a few expletives under his breath as well a hundred years ago! your channel and efforts are all genuine and all in very good show. cheers!!
amazing work!
Quite the punch in the second flight
this channel is sooooo underrated!!!
Fabulous, in terms of the numbers of comments, you have hit an aerospace nerve! A kind suggestion only as you clearly are experts; a slightly larger airlift capacity of the rocket might allow you to control the post thrust portion of the ‘flight’. For Goodness sake, do not give up and keep up having fun. Australian rocket scientist probably started with a lot of fewer successes. Next video? Greetings from down under
I just started watching ur videos on my school computer, there only few channels active on my school TH-cam and it includes ur too and I'll be honest u read my mind thats how I wanted to be!! Love from India 🇮🇳
Loved this!
That was awesome you gatta build another one
Oho.... Another awesome 🚀 video 😃👍
6:30 i felt the pain
this is epic man keep op the good work
You should make a big red button on your control panel and have it set off an emergency parachute inside it and print ABORT onto it.
Fantastic videos and great project. Funny to watch and good you take all with a grint of humor.
Atleast you started to make high power RC rocket (controllable). In future I can expect more efficient controllable RC power rocket👍👍
4:38 dude, i just realized you got an awesome style man! Seriously, very nice fashion! xD
Perfect weather!
:o
So close to 100k!
Super cool, definitely need a flight controller and some stiffer control components though.
I randomly found your channel because of this series and am a new Sub now
The original orange one that big would have been awesome.
awesome video
Really enjoiyed this, and you seem a real good person, watched two videos, and im happy to sub to you after just the two, thank you for the content, its top quality.
I appreciate that thanks!
Love the sound lol
We will need people like you considering where the world is headed. You will get more roll stability if you just flip the whole thing upside down so the wings are on the top.
Living vicariously through your experiment . Love it !
Wonder if your control surfaces are too large for such high speed .
No joke, but that looked just like a cruise missile, great jobs on creating such a cool rocket plane!
6:16 You made a pretty good ballistic missile lol
Ohh what a good laugh! 😅 Thankyou
It is funny that you use meters and miles per hour in the same sentence.
I think that the best ways to improve the aircraft (without the obvious and expensive answer of using a LH LOX engine with refactory nozzles and regenerative cooling with the liquid fuel (preferably in an expander cycle)) is:
1: eject spent rockets and ignite the next solid rocket above it (longer flight time & faster speed).
2: make your fins for the control surfaces out of aluminum or a tougher material per unit weight.
3: Try to write an autopilot program to use the control surfaces to make the top of the camera frame face the sky.
4: do what another commenter stated of having the rocket initially travel upwards and level out once the first engine expires.
Good attempt!
THAT WAS AWESOMEEEEEEEEE.
I think the weather in his area is a disadvantage but also an advantage, since it gives him time to think thouroughly and prepare his projects. That's also why I love his vids!
I like your positive thinking :D
A flight board with gyro stabilization built in might help for the level of development. Trying to correct small changes in direction manually at that speed would require razor shape reflexes. Thanks for sharing.
Errr, think you need a parachute there mate. Good job overall!! Very cool!
A few tips for FPV, James... 😬
- If it's an airplane, use a pusher. If it's a quadcopter, always change the props.
- Always clear your SD cards.
- Always charge the goggles' battery! 😬
Anyway, fantastic work as always!!! 😃
Stay safe there with your family! 🖖😊
Good job bro💪🏻🇲🇦
Woah, a super useful sponsorship? Dope
The sound of it at the end of the video. Kinda dope, thing took off like, well…. A rocket LoL
