I did like Tony did,
I programmed in my cuve; on the futaba I can choose a 14 point curve. I Plotted out points 1-14 and the corresponding RPM with a linear curve. Then I choose 14 equally spaced RPM values and programmed the 14 points for that curve. Result is a linear response on the throttle. I have to admit at first it felt unsettling - like I had no power, but the truth is I was just used to all the throttle being below 1/2 stick. Once you get used to throwing the stick around it feels good.
