Me and solarsupremacy has been lookin' over it and came up with some solutions for planes, but it has to perfect before I can add it to the guide. That's a WIP at the moment.
BUT!
I have a post for auto-stabilizating rotors in the guide, but it's pretty weak if you use only 1 rotor. My U-5 Intelligence on the other hand uses this system with 8 rotors and you can clearly notice the auto-stabilization.
