You would be money ahead by getting a good PCM radio, sharpening your flying skills before flying expensive planes and forgetting the gimic garbage to keep it right side up. If you can't do that yourself, get a wild thing .15 size plane, set it up really sensitive and learn to fly it really well. You will be a lot better pilot. Copilots and other things may keep it right side up or fly it for you, but they make you lazy, don't teach you anything, and do nothing to improve your skills.

You fly RC for a reason. To fly them. You don't need cheater crutches to fly them for you or you are not flying the right kind of planes.
