Ardupilot Helirsc. Set up of collective and throttle channels Traditional Helicopter If >1200us, it enables the Motor Interlock function, below it is disabled. The Rotor Speed Control (RSC) uses the heliRSC output (SERVOx_FUNCTION = 31) to the engine throttle or speed control/governor to control rotor speed

blue0827ww (chen pu sheng) December 24, 2020, 12:12am 1 RSC setpoint (:ref:`H_RSC_MODE ` = 2) - this mode is used for helicopters utilizing either an electronic speed controller or an external governor for internal combustion engines.

blue0827ww (chen pu sheng) December 24, 2020, 12:12am 1 // @Description: Sets the throttle output (HeliRSC servo) in percent for the throttle curve at 75% of full collective travel where he 0 percent collective is defined by H_COL_MIN and 100 percent collective is defined by H_COL_MAX. Enabling inverted flight only changes how ArduPilot stabilizes
GitHub ArduPilot/ardupilot ArduPlane, ArduCopter, ArduRover, ArduSub. Servo #8: HeliRSC But this doesn't make tail work with ddfp but if I make it servo only (which doesn't have any shaft or belt connected to main motor), the tail also works due to torque created by main motor when it is working but it is not enough to counter enough The channel must be over 1200us in order for the heliRSC output to follow the RC input
Ardupilot Heli YouTube. So if you are in stabilize and arm and enable motor interlock, then the HeliRSC servo output will go to the point on the throttle curve that is associated with the blade collective pitch given by the stabilize collective curve Demonstration of a real-world commercial flight with a Trex 600 helicopter flown with the ArduPilot system, including additional add-on RC telemetry and FPV
