Hi, I am trying to enable dspoiler on a X8 wing with 2 servos in each wing. I am using the elevon_output for hardware elevon mixing. I am using output channels 5/6, but I have tried both 7/8 as well. If I set the RC5_FUNCTION to something like "Aileron" or "Rudder" the servo does move, but if I set it to 16 or 17, the control surfaces do not move. Is there a parameter I am missing somewhere?
