I'm curious. Why do you think it "not satisfactory" to go straight to full throttle for take-off ? That's exactly what 99% of the pilots at my club field do and it seems to work fine. It certainly works in FMS.

Let's face it, if you're messing about with keyboard and joystick instead of using a Tx interface it can't possibly be accurate anyway. That simply isn't how people fly R/C planes.
