Kerbal Space Program

Pretty sure we don't have a thread for this yet, so here it is. Share your extreme insanity here.

Let's start everyone off with a little challenge. Download the KAX mod, and go to thine spaceplane hangar. Build a plane with only a single A7 AeroSport engine for propulsion. I want it to he able to fly for at least five minutes, and land back on the runway, without using any torque wheels for control. Control surfaces only. Other mods may be used, but the only propulsion you can use is the AeroSport.
Bonus points: Build it at under 10k cost and 5k kg in mass
Extra bonus points: Make it controllable enough that you can fly over the water at under 25m without crashing

I made a plane that ran off of a physics glitch once, didn't have anything except control surfaces and a cockpit.

My rocket ships keep doing summersaults when I decouple a rocket stage then ignite the next rocket.

Please help.

Pics of the offending rocket and I'll see if I can figure out what's wrong

In general.

Classic penis shaped rockets

Not much to go on there, I'm gonna need actual pics of the actual rocket to work out what's going on.

Sounds like too much mass at the top.

For each stage, the mass should be as close to the engine as you can make it.

Also, for in-atmos stages, you can add canards to the tank to help mitigate the issue.

Also reaction wheels, depending on the size of the rocket. A massive, multistage, 2.5m beast will do crazy things if the only reaction wheels are in the command pod. For big rockets, I'd say like one reaction wheel unit per stage.
