I do use a TX interface, however he's either a.) too poor, b.) too cheap, or c) not comited to buying an interface until he sees if he likes/needs FMS so he wants to use his keyboard/joystick to try it out. The full throttle option with the keyboard only works on his PC if you keep the key held down and that's a sucky way to fly it. I agree he should use his TX, then again, he could spend a few $$ and go for a real quality sim like G2 (which is still not a 100% acurate substitute for stick time). What the heck, #1 son is 40 and he and grandson are spending the inheritance fast enough on RC and we fly almost every day year round. -
The question still remains how to ramp up the throttle on FMS using the keyboard as the developer claims the program can do. Do you know how to do this?

P.S.
In the last 45 years of modeling I learned not all planes take slaming the throttle all the way on take off. Some times and some planes require gradual throttle application. Try it on your Cub or scale plane sometime.
