Okay ... you are disabled, you cannot handle things on your own. So why not try this. No need any special controller, keep it simple. Get a simple 3 channel plane. You fly on 2 channels and a friend assists you on the throttle for a simple plane perhaps? Its no more work than training a newbie. Both just sit down and relax and have a nice cool lemonade as you fly. Friend sits on your LEFT, you only need a Mode 2 TX.

I got friends who fly easy planes on one stick only when they are in the lazy mood. I do it a lot on my Lazy Bee. Hence, nothing special needed.
