Warning: This is a bit of high level useless info in case you care, not meant to confuse the original issue


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.

What about me?

To me, Expo makes the plane feel sloppy. I keep it around 10-20% neg. Whats happening is I like to have my plane respond when i move the sticks. The more expo you dial in the farther over the stick needs to go to have an effect on the control surfaces. If you were to fly a plane at zero for a while, then dial in 50% you'll be over controlling like a mama until you get use to it. Your making a right turn and you keep moving the stick right and right and right and nothing until wham-there it is.
