I have assembled the BlueROV2 and everything seems to work so far except the camera tilt.
I have tried plugging into CH8 and CH10 and setting the output channels to CH8 and CH10, while keeping the input Channel as CH8 (configured in the parameters tab as camera_tilt). I tested the servo on a different platform and confirmed that the hardware for the servo works properly.
I am using QGround Control (version October 19, 2016) and Windows 7.
Does anyone have any suggestions?
