Hi, I finished assembled Blue ROV2 and testing it now. I have few issues now.
When I start it in the depth hold mode, the motors spin more and more quickly and it immediately sink to the bottom of water and once I change back to normal mode, it is getting okay.
All moving functions are working fine except CW and CCW turning. It is not moving properly when I give a commend. It seems 2 thrusters are turning wrong way.
