(Therefore the rotors will not generate torque, and if this happens to only one rotor of the ch47..... On the bo the effect is smaller; you just need anther position of the pedals...)

But I will check everything with the ch47 after finishing the coding. Please send me your ch47 config (or is it in cvs?). Probably there are some wrong signs for clockwise rotating rotors. But the sign of the torque seems to be correct; if not the ch47 would not be flyable.
