I use Taranis Plus with X8r. Set up 3-position switch to do 3 flap settings on Inputs. Set it to channel 6 in mixer. Proved it worked ok in channel monitor. Then saw it worked fine in Mission Planner Radio Configuration. Used BEC to power servo rail. Everything except flaps works fine: control surfaces and throttle.
Connected servo to Pixhawk channel 6 to test flap positions. Nothing, no response.
3dr help couldn’t find anything, so I have hit a wall!
WhaT ELSE CAN i CHECK?
