Flyboy,
I have two of the same radio that you mentioned (Futaba 6EXA). You can set up expo on the transmitter sticks to soften the center of the controls. This may help the early flights from being as jerky for you.
As you say the Futaba 6EXA has expo, as well as the rates can be set and switched from Hi/Lo. When I do actually fly my second plane I should be smoother with the controls. I do know that a high wing airplane will fly a lot smoother and is more easy to fly than most low wing airplanes. I am pretty smooth with the controls, even though I have not done a lot of real flying I do fly a lot of flying on the sim.
