Building the WORLDS FASTEST RC Rocket Plane!

When soldering, I find if you put the iron underneath the joint and let the heat travel up it works much better.

estes motors that are labeled D12-0 do not have a smoke delay (as indicated by the 0) or parachute ejection charge, but they do have an ignition charge to light the next engine on top of the D12-0 (as this is how they are intended to be used). This ignition charge is what ejected your motor.

What I found ironic and fascinating was that as you worked on modifying the model's overall design, it started to turn into a German V1 Buzzbomb.

Seeing Modelplanes fly always make me a little bit emotional because my grandfather always build these and flew them. Reminds me of simpler times

This is amazing dude! Also I can't tell you how loud I screamed when I saw the train going by in the background of your desk shot. So jealous of your office!

What a great project, it makes me want to buy some of those motors and do some tests. The camera is like a big aerobrake, if you remove it, you may gain 10 or 15 mph.

I feel like I speak for most viewers from America when I say, we appreciate you doing conversions to MPH for us!

This was a dream of mine as a kid building model rockets and Rc planes with my grand dad! Those experiences drove my career choices, first into aviation as a jet engine technician, then into aerospace as a rocket engine technician. Loving this video! Only suggestion I have that you may have ended up getting to, some cheaper model rockets use a metal tab that holds the engine into when the ejection charge fires. I’m not sure why your engines keep jettisoning, but a tan on the aft and vent on the front should prevent that and maintain stability.

What if you mounted the camera in the rocket nacelle nose cone? It would bring your CG back, put the weight midline, and be simpler than cutting into the foam wing or foam nose.

Just a quick note. You're looking for motors ending in a P for plugged. 0 means there is no delay before the ejection charge. Great vid looking forward to the next one. 👍

On behalf of everyone I say that this beauty deserve a pair of landing gear..

Love the projects so far and I’m more than excited to see the finished product of the V2 Jet Car because that design looks flawless and very aerodynamic, I know it’s capable of some amazing things. I just wanted to ask if you’ve thought about experimenting with VTOL on an aircraft. I don’t know what sort of benefit it would bring but I think it would be a nice thing to at least attempt.

Your roll oscillation may also be "aeroservoelasticity," (ASE) also known as "flutter." Nearly all aircraft exhibit ASE at some high enough speed; it's usually a factor in the high speed limit given in the flight manual. The wing's natural flexibility (elasticity) can couple with the controls (servo) through aerodynamic loads, and result in oscillations that often result in failure of the structure. If you're getting the beginnings of ASE at 130MPH, you might get fully destructive oscillations at even slightly higher speeds. Typically the onset is rather sudden and even a few knots of airspeed mean the difference between some mild instability and runaway destruction. Yes, it could ALSO be simple gyro gain issues, but you should not fail to at least be aware of the possibility of ASE.

Excellent project...two successful missions with rocket assist is very impressive. Can't wait to see the speed record get set!

I'd sleep much better at night if I knew there were more young people like you to trust our future to. Never stop being curious!

Been there done this. I centered the engine at the CG and made it eject when spent to launch gliders. You can also use a rubberband plane wound up, have a small metal pin stop the prop from unwinding. Then have a string tapped to the rocket engine and tied to the pin. You launch the plane with the rocket power, the rocket engine ejects pulling the pin and then the rubber band powered prop takes over. Had cometitions at the field to see who could get highest/farthest/duration from modded foamies.

This project is a reminder of the NF-104 of which Lockheed built 4 (I think) examples in 1963. They put the rocket motor in the vertical stabilizer with a significant downward thrust. Your project looked like a blast, thanks for posting

When you unboxed the jet, I thought "Nice, shame what's going to happen to it." But it survived! I do like an episode with a plot twist.

Did bro turn into markrober??

This is amazing. Love that whistle on the last rockets ignition. Super cool 😎
