Hi,
This thread might develop into something interesting.
I use 3 flight modes to suit particular maneuvers.I do not use throttle trim at all.
1 ; My normal ; low t stick = brake (I use 30% max on a shulze), one click up = 15% brake, 2clicks = free spinning.
2 ; Stall turns ; In this mode I get high rate rudder + high tick over ~ 1200 to 1500 rpm (have not measured it - shhulze min = 800rpm).
3 ; Spins ; High rate elevator and rudder ,same high tick over but now an elevator to throttle mix to reduce the motor speed as elevator is applied. This is a little tricky to set up but once got it works extremely well. I have it so the motor is stopped completely by ~ 25% elevator. It gives me great spin entry control.
