Thanks for your input. The plane I fly in CRRC is the Angel S30, and it does not self level in any way. I can land it properly though, and did a barrel roll, a full loop and a half loop which I rolled out of. I still crash like 1 in 4 times, usually from wild flying.

I'm flying it with ailerons, with no rudder input. Is that a mistake for a beginner? The only problems it gives it that when I level out for the landing approach, it tends to go nose up an I have to force it down a bit, where I'd rather be just gliding.
