The following assumes a FUTABA radio where Negative Expo makes the center LESS sensititive, JR/Spectrum is opposite...

@ 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.

@Osiris: if you want to fly helis get a heli radio, its easier to fly airplanes on a heli radio than vice versa. A DX7, 9C, or 9303 are all excellent choices, buy the best you can comfortably afford as a good radio will last you a long time.

@fatcat: If you paid for it, use it! Most of us don't drive automatics and go around manually shifting the gears up and down Learning how to take advantage of the features of your radio is part of learning.
