@ gboulton: Actually, round servo outputs already have positive expo built in. The control surface responds more while the servo is centered than than at the extremes. About 22 percent negative expo or so acutally makes the control surface reaction, in relation to the stick movement, linear which is what I prefer.
True enough. I was trying to keep it simple.

Should have pointed out that i was using a generalization, however, instead of spreading inaccurate info. Good catch.
