I've recently switched away from a traditional RC controller for a simpler joystick (simple PS4 controller) setup over telemetry. Typically, my flights are fully autonomous, but when I do try to take over control, the flaps are deployed and I am not able to control their up or down position from the joystick.
I've tried setting
RC_MAP_FLAPS to an unused channel and although this works when I use a traditional RC controller, it doesn't seem to work with the joystick.
Has anybody had luck with flap control with a joystick (No RC) setup?
