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

[BPSspace]

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!

[CuervoRC]

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.

[banditboy]

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

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.

[benanddadmechanical]

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.

[wilgarcia]

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. 👍

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.

You all are spreading so much joy. Thank you for being so wonderful!

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.

[robertstark]

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

[anoobis]

Great work man. Excited to see the improved version

[lyndonfisher]

Really engaging and fascinating stuff. Hope you become oneo of the UK's top flight engineers if that is your goal. Magic!

[nighthawk]

Nice job. If you are set on sticking with foam, I would definitely look at sanding the trailing edges and covering with a glass fiber cloth. A bit of work, but sometimes it's about reducing drag, rather than simply adding more power/thrust/weight etc

[BreakWindDrone]

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

[ryanmartin]

Reinventing and reviving the good old JATO pack! Great video and even better garage engineering.

[TheTonester]

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