Quite weird situation…
Simple ROV 4 configuration, thruster 1 to 4 connected to MAIN AUX 1 to 4 on the pixhawk. When I press the mount_tilt_up or down button the thruster moves forward and backward. In the meantime is not responding to forward/backward command (only thruster 2 is correctly responding). Thruster 3 and 4 work with no problems…
The camera is working though.
It may be some misconfiguration in QGC? ESC and motor are working (tested on another channel), then the problem is either the pixhawk or QGC…
