i fly helicopters, and yes, the blade pitch is collective and can usually be changed from 11 to -11 degrees, and usually works when the motor is ran at a constant rate (head hold mode) and then the throttle stick is used for controlling pitch(ie center throttle = no pitch, 100% throttle = +11 deg pitch, 0% throttle = -11 deg pitch)
I thought it was twist throttle, raise/lower for pitch?
I'm surprised that it appears a lot of people don't know this already.
