I set up GRAUPNER HOTT GR-24L receiver with cube orange Pixhawk by in put s-bus port to RCIN channel.Then, flight control can detected a signal from receiver (show on radio calibration page) but all of servos can not operates.
Why are you messing with SBUS?
You can use PPM (SUMO) or Graupner SUMD protocol.
The GR24 needs to be configured for the protocol you decide to use.
