Clarence,

That is a very important point. Regardless of the instruction method, instructors need to teach that the control movements need to be smooth, deliberate, and minimal. I teach students to plan their turn, deliberately feed in a set amount of aileron, ease back on the stick, deliberately roll out on the new heading and ease the stick forward, and then do nothing.

Periodically I will hold the transmitter well away from my body with my fingers very deliberately OFF the sticks to show the student that the airplane will continue quite nicely without any help from the controls. I also will put the airplane in an uncomfortable attitude, then chop power and set the tx on the ground to demonstrate that left to it's own devices, a properly trimmed trainer airplane will "save" itself.

I think anyone who fancies himself an RC instructor needs to spend 100 bucks and take some dual from a full scale instructor, ideally in a Cub or Champ. I think there are an awful lot of RC flyers, including self proclaimed instructors that really do not understand how an airplane works.
