I am trying to get manual operation of flaps on a Pixhawk. I’ve set FLAPS_IN_CHANNEL to 7, set some nominal values for FLAP_1_PERCENT, FLAP_1_SPEED, FLAP_2_PERCENT, FLAP_2_SPEED, and tried setting SERVO13_FUNCTION to both 2 (flaps) and 3 (auto flaps). Neither works–there doesn’t appear to be any output on that servo pin at all. Can anyone think of what might be wrong? All the other control surfaces (ail, ele, rudder) work fine. This is for a quadplane–does that matter?
Thanks in advance.
