One thing that has not been mentioned is getting rid of a throttle with the conventional detents and going to smooth friction such as used on heli transmitters. I did this years ago for most of my radios. I firmly believe in a good mechanical throttle curve (differential) but even with that, with a course detent on the throttle stick, one click more or less throttle can be way too much. With a smooth throttle you can put it exactly where you want it. It would be nearly impossible to fly a heli smoothly with a ratcheted / detent throttle and collective stick and the same logic applies to an airplane throttle. Try it, you might like it.
