To JRF and Bubba. Thanks for the information. It was extremely helpful. I blush to think that I had not even considered the mechanical advantage in hooking up the controls. I have tended to hook them up any old way, and then use the computer radio to give the proper movement, which often resulte in way less than the 100 % movement. I'll stop this practice at once.
I am also interested in your comments on exponential. Why is this disadvantageous to use? Thanks again, happy landings.
