I like planes. I like rockets/space. I have model rocket engines from a few years ago. I have a Cargo plane with a large enough cargo bay. LINK:http://forum.flitetest.com/showthread.php?19823-Twin-Boom-Twin-Engine-FPV-Cargo-Plane-Build-Thread
So, being the Mad Scratch Builder I am, I decided to mash them together to build something awesome.
I first needed to mount the rocket engine in my plane, which presented it's own challenge.
Technical Bit:
I have a PVC pipe with an end sealed, the engine itself, and an O-ring holding the engine in place (which worked better than expected) The ejection charge would simply knock the engine out the back.
THE TEST:
I was trying for about an hour yesterday, but earlier, I got it to work.
Let me know if you have any concerns about me putting this on a plane (be honest)

Technical Bit:
Most model rocket engines have 3 "stages" of fuel: Propellant, Delay, and Ejection. The Ejection charge is basically a little explosion which, on rockets, blasts the parachute out the top end so it doesn't lawn dart. But this is no model rocket. So, I anticipated there will be a little explosion and I decided that the best way to not have the plane explode is to shoot the engine out the back. NOTE: If you want to try this sort of stuff, you can get engines without an ejection charge. I'm lazy and broke, so I made my own problem.
