@BLUBLUD huh?
What is that red launching stand called as???
I've Seen it in many videos.
You need a third stage with a parachute. Just a small one for braking before impact.
for that SUPER SPEED, you would benefit more if the rocket motors were linked in series. EXAMPLE= 3 motors fired at once will give you less velocity than 3 motors fired back to back. you are really really really looking for long burn time. off the shelf rocket motors do not provide this, except in a multi stage config. If you want to break some speed records, ditch the electric motors (drag)...attach the rocket plane to the belly of a carrier plane...release mid air, fire the multi stage rockets with your control trims set low. BINGO BONGO, YOU JUST HIT 200MPH. but what would i know, i just work for northrop.
Folding prop - shut ogf electric engine just before ignition..? 🤔
"mmm i've lost complete control! Better ignite the rocket engines!!" Wahaha great stuff mate, had me laugh :) 👍
Was that accidental? Lol
the cartoon moment... the rocket boots ignite after you hit the wall.
North Korea ICBM moment
Hahaha
Heheh
"A nose heavy plane will fly poorly, A tail heavy plane will only fly once"
@@spectrey1936 That's from anyone who forgot to check CG before a maiden.
@@joebaldenweg true
Checking the static center of gravity is far too easy. Skipping that step during a build doesn’t even make sense. Then he forgot to allow for the ejection charge as well? Slow down a little... make a checklist and follow it. Pay attention to the important details and be proud of the results.
and a center heavy plane won't!
ANY naval vessel can be a minesweeper ONCE...😊
Have you thought about using a prob from a glider, the ones that fold back when not in use. Might help having them fold back when you hit the rocket... loving the videos by the way !!
Yes I was thinking about using one if I am to continue with this hybrid system! I may return to pure high power rocket planes in the future through, perhaps dropped from a drone (with increasingly huge engines 😉 )
@@Project-Air if you do so - which I think is a great idea - make sure to cut off the power when you switch to rockets, as the propeller might ruin the blades if it folds while spinning
Came here to say this!
@@Project-Air can you name the white plane Sielulintu? (Finnish word, approximate english translation is "Soulbird". They are creatures from finnish mythology, wich bring a person's soul to their bodies on the moment of birth, and on the moment of death they bring the soul to the afterlfe.)
@@Project-Air That would be cool to do FPV. They say the trick to flying is to miss the ground...
use parachute if plane is hard to land and ripping motors
Too much weight
@@TheNuclearDragon it probably would not weigh much
You show great tenacity James, good on you.
I try my best

Ok
DO NOT put a folding propeller ! You can extract a lot of thrust from you propeller even at very high speeds. You should consider putting a higher pitch propeller, and/or go to a higher voltage battery to get higher RPM.
He not getting heared😔
Look at some as3x gyros they are a godsent for small planes in bumpy weather, there only made to keep the plane stable it wont do anything lie the “safe” gyro, it just keeps your plane pointed where u point it.
I also recommend practicing landing multiple times every time u fly not actually putting the plane down just practice keeping it slow and putting it into ground affect
I had a bad day and seeing you succeed brightened up my day! Amazing video James! I think you need an esc with a brake feature(my turnigy plush-32 has one) to stop the motor immediately while still having speed and a folding propeller to reduce drag, as the area of a non folding spinning propeller that produces drag is equal to the circle that the prop makes when spinning and not just surface area of blades.
A folding prop is what I would have liked to have used on the MK2 plane in this video, in an ideal world - would like to test one in the future! ☺️
@@Project-Air They're actually pretty cheap, no more than 15 bucks on hobby king and you can find different blades sold separately for spinners on banggood and aliexpress
@@Project-Air what if you use higher pitched props that way you can still get some power off of them whilst the rocket is on, though depending on the pitch guessing it might need an air launch
@@diogonunes1865 more pitch would increase speed but also load the motor more
@@linecraftman3907 yes it would load the motor more at low speeds but would prevent over revving and extra drag at higher speeds
So firstly, this was rad! :D Secondly, I have lots of suggestions! I'd like to agree with both (1) the people saying use a canard and/or delta config (easier for CG, they are SO forgiving) and (2) the people saying use a higher pitch prop rather than a folder. I'd also add, try to have more tapering at the rear of the craft, and taper the trailing edge of the wings to be thinner - you're going to lots of effort to make a lovely nose cone, but rear streamlining makes a way bigger difference to drag reduction than frontal streamlining. And then, cashing in some of those savings on parasitic drag, you could afford to have just a little more wing area, for a much easier takeoff and landing.

*of course it is mate*
don’t worry, this video isn’t over yet..
WORDS of INSPIRATION!!

Moooo
Thanks for all the milk!
😊😊😊

The whole time I was thinking "why is he testing the electric mode of the flight without an appropriate mass at the rear to represent the rocket motors?" Aaw well. RUDs also make for great videos, well done with the project, and I really hope that you still plan to try again with a tweaked original design
I love your smaller airplane ! Weight is absolutely critical, especially in rockets. To go faster you should put a propeller with a bigger pitch, so it will not overspin when lighting up the rocket, which makes the motor ineffective.
THANK YOU for showing when it goes wrong and you have to study why. Then with what you have learned build again, over and over until you get it right.💯👍
Folding electric props would solve the issue, or put ducted fans on it, cool little project. Bravo!
When those four 'D' engines popped off on the ground, I got a good laugh, thanks, needed that! Good recovery.
This whole project kinda reminds me of the HE 161, or the first tests of the ME 262! Love your videos, keep it up!
No worries mate, your not the only one who had gone through that path before. Like your perseverance, keep up the good work.
Very nice work! Yes, I'm an Estes afficiando as well. Dial back to 1965 and my family roll up to the Estes Model Rocket digs in Penrose, Colorado! No one in town knew where it was. I was deflated. I imagined a small NASA. Not so, just a couple of ladies fulfilling orders in a small shed for grommets like me.
Btw, you should look into using the "plugged" rocket engines instead of the upper stage type. The plugged style do not have an ejection charge, and they have a clay cap to prevent the hot gasses from exiting the forward part of the engine as happens with a booster type. D11-P from Estes is a good example, or the smaller A10-PT.
Awesome man! Love these projects!
Maybe you need a folding prop or something like a small pylon racer prop with more pitch than diameter to have no drag and maybe additional thrust when the rocket boosters are ignited.
Can't wait for your next video!
Came here to say this!
Loved the Almost VTOL take off on the Ducted Fan test flight, Dropped its tail and then off she went. Cool
Really glad you tried this. was a project 14 year old me always wanted to try. RC tech hadn't progressed to the point it was practical and Pre job dollars were precious. Good stuff. Good on your sponsor Brilliant.Org for helping you out.
So, supersonic rocket plane?
The biggest problem on this channel is the weather
I have been quietly anticipating the next video and you certainly didn't disappoint , Awesome content as usual !
Best yet.. would be good to see a continuation of this with you beating your record!
Imagine getting a mini pellet mini gun and building mini a-10 with those ducted fans
this is awesome stuff! What’s your educational background?

It's great to learn from your videos. Mostly I love your enthusiasm and tenacity. Good luck and thank you.
Watching all you guys on youtube has definitely inspired me. I've built a few planes this year, and have plans to design and build even more.
UA-cam creators are the true "influencers.."
Nearly vtol in the beginning there 😂
This reminds me of when I was a recruit technician for a guided missile project during the Cold War. One day I misaligned the trajectory on one of the prototypes and ended up obliterating a Cattle Shed 2 miles east of the testing facility. Little did I know back then that farm was owned by Jebediah Lipman, who would go on to become my greatest rival in the tomato empire for years to come
Such an amazing person. It’s lovely to follow you and your amazing mind on these journeys. I share them with my little ones as well and don’t mind saying, if any one of them is as successful, intelligent, driven and humble as you, I’ll be one proud father! Keep up the amazing work. Inspiring to say the least!!!
If you set the motor brake to ON using the ESC programming, it will minimize drag on either props or EDFs and allow the ROCKET to maximize the thrust with minimum drag.
Flying wing
One D motor in the back, one propeller in front
Could we see a continuation of the Jet Tip Helicopter? You could try incorporate it as a mini gyrodyne.
This is extremely quality material in every way. Well done!
Love the way rocket plane Mk2 tore across the sky. Awesome stuff
Step 3, make it nuclear powered
Cool build! Keep up the great work!
This reminds me of when I was a kid in the 70s. I was into model rockets, fireworks, airplanes...if it flew or blew up, I was all in. There used to be a styrofoam toy plane called a Delta Dart. They cost $0.10. They had a little tab under the nose you could affix a rubber band on a stick to pull back and launch it. I always wanted to take a bottle rocket off the stick and attach it to one to see how it would fly under rocket power. I never had the bottle rockets at the same time as a Delta Dart, as it was somewhat difficult for me to come by fireworks as a kid. I did modify the shit out of my model rockets, however. Getting rid of the motor mount and just stuffing a D engine into one, or taking a small streamer recovery rocket, nixing the recovery system and gluing the nosecone in place so when the ejection charge went off, it just ejected the engine out of the rocket and it would just come down nose first into the ground (Estes Wizard). Good times.

Love your persistence. If your using Cura to slice, in mesh fixes, change the maximum resolution to .5. You will get a much smoother print.
Enjoying this kind of videos. Theoretical vs reality 🙂
Keep on inventing and challenging yourself!
Keep the vids coming James. Love your work 👍
This is going really well. It's just so cool!
0:05 ...this take reminds me to the sequence of the movie 'The right stuff', when Chuck Yeager watches the X-1 being fueled and the vaporizing fuel forms misty clouds...
...nice 'easter-egg'...! ;-)
so glad I found this site , always interesting and well done
Great Job 👏🏻 !!!! Please do more of these !!!
You might want to look into folding props like what they use on gliders, you could go full throttle then right before ignition, cut it and it should fold and have a lot less resistance
the fact that you build a whole new plane and didn't even try to monetize the construction of that is very respectable man!
Fantastic work, James! Really well done!!! 😃
It flies great!!!
Stay safe there with your family! 🖖😊
It was so stable when you fired the engine inflight. Nice!
no thank you, i have been in a dark place there i had no what so ever feeling for flying RC, but it starting to getting back now watching this!
Muito bom seus vídeos, estou adorando ver eles!
Magnificent!!!!! Keep going, make the amateur U.K. space program proud!!!!!
I found one of my favorite channels, this is right up my alley.
Actually... listening to you is like to read some article...
Am impressed!
Great to see experimental aircraft being developed. Crashes are all part of the hobby.
could you put a rocket on a helium balloon, let the balloon rise to space, then launch? it would be the coolest video ever
I like this idea.. No waste of energy to reach altitude and you could get up to max speed in a vertical dive usung the electric motors before activating the rockets just after you levelled out.
I only know this when I mucked around doing similar stuff with my two kids other people told me it would not work but it did. It Did not like it just with propelled engines on their own but soon as I hit rockets made a hell of a difference just wished I kept the videos of it.
Thank youf or this video .... I really appreciate that..keep making this👍🏻✌🏻
This is a message is a clue to never give up
That went fairly well, and the concept is definitely proven. Depending on how you want to proceed, if at all, she has a lot of promise. Unfortunately you will have drag from the primary motors, but I think 125mph achievable. Another great production mate, looking forward to more as ever. Be well and safe.
Great Work! I think there is much Room for Improvement. Might I suggest using an EDF and a Closable Air Intake... something like in SR-71 Blackbird. You could close the Intake just when the Rockets ignite and open it again just after the Boost, hence reducing the prop Drag.
To combat the drag issue that the propeller may cause, you could implement a folding spinner like some powered gliders use, suchas the E-flite radian
Nice work.
Excellent video.
Keep up the good work
Great vid man iwas waiting for this
I'm sure you probably already know that Hobby King used to sell an Me163 into which you could install a rocket motor - the motor they recommended is a C6-0 the 0 on the end means that there isn't a parachute ejection charge - it would be interesting to see not just the max speed but how much was added to the propeller speed by the rocket
Mate your a BRILLIANT young lad, your parents should be proud. :)
Love your videos and trial and file with the plane
Awesome video! Thank you.
That first take off reminded me of aircraft carrier taker offs, because the fighter jets drop bellow deck height before climbing into the sky.
Very cool video! Keep up the good work!
Great project! Hope to see more.
That mid-flight mini explosion on the underside of the second plane was cooool. 😄
Adding weight and wind resistance is counter productive to your goal. You should lighten the aircraft and use a bungee type catapult if you want to light rockets while in flight. Either that or drop the rocket plane from an RC plane just like Bell X-1.
Loved it! This is so cool!!
Great video and project! A suggestion regarding overdriving the motors under rocket power. Look for "lift motors" used by RC glider pilots. They have fold-back propellers that are designed to fold-back flat when the power is cut. Perhaps you could use one/two of those for the electric-powered portion of the flight, then cut power just as the rocket motors kick in. Keep up the great work and thanks for letting us learn-along!
Awesome project and video.
58000 subs - congratulation the channel is finally on a steep growth path, thanks.
this guy is so interesting to watch keep up with your good ideas!
Awesome job 👍. Maybe a folding prop? I've been toying with the idea of adding rockets to an edf airboat. Inspiration for a winter project. Keep up the good work.
Just an idea for the landing pad, use spare or extra cardboard boxes layed out and slightly held down by lightweight stakes so during wind, your tarmac is safe and recovery of your craft is higher with minimal damage.
Use those folding propellers you see on rc gliders. That might help a good deal on the drag created by the prop when you ignite the rocket
great vid, great project thanks buddy
Congratulations for your hardwork bro
You can change the props of the motors for replegable ones to reduce the drag when you activate the rocket engine
You can power lights with a brushed esc too. Then you can dim the lights or turn them off and on in flight.
Try to use folding props with esc braking to decrease drag when you fire the booster. This should let the prop blades fold back becoming more aerodynamic and the esc braking will stop the motors from spinning therefore preventing an accidental opening of the folding props.
I hope this helps,
Jeb
Great video! I’ve wanted to do this for so long, glad to see someone do it. I’d like to see what would happen if you over propped the motor so it would work better under rocket boost.
Aerodynamically, I would put the EDFs inside the body and put the smaller rockets under the wings. With the thrust of the rockets it's going to rotate into a loop. CG a little forward if you can. I've done something similar and nose heavy helps with rockets.
The rockets should be located along the longitudinal axis, preferably as close as possible to the center of the body so they won't exert a severe pitch up moment. Under the wings is BAD.
@@aGabay test it with a glider and smaller rocket. You need the nose weight or it's going to rotate to a loop. Under the wings, forward of CG or close to longitudinal axis either way. Still needs to be forward of CG unless you use a low thrust to weight ratio.
@@nothingtoseehere4026 This way, you are going to shrink your stability margin. Not good.
@@aGabay put a C rocket directly CG on a stryrofoam plane. I think they're about a 3 ft wing span. You can buy on Amazon or Walmart... Fly it and you'll see what I mean. Heavier wing loading might help though.
@@nothingtoseehere4026 I don't know anything about model rockets... I prefer suck-squeeze-bang-blow engines 😜
Ditch that prop. The propeller drag limits your top speed by a lot. You can try a folding prop (like an electric glider), but I doubt you'll find a fast enough prop. If you go that way, program a prop break, then speed the plane to it's max speed and brake the engine right when you ignite the rocket.
Also - your CG is too far back on all flights. I think you are trying to apply general RC plane rule of thumbs to a plane that's really not generic. Your stability margin is smaller than you think. Also, you got to take into account that you are burning a lot of mass in a very short time period.
Modern pylon racing props might be suitable, there are some small 7x13 folding props which are used up to 320km/h. I managed to push a 250g model to 270km/h with one of those.
very cool and interesting project thumbs up :D
Using normal propellers has a lot of drag, use turbo jet combustion engines and the thrust will be much higher.
