Hello, I have a boat using ardupilot in mission planner but only one motor is spinning. When I connect power to the esc’s they start beeping rapidly, and when I turn up the throttle only one motor starts spinning. If I reverse the esc’s the other motor will start spinning. I don’t think the problem is with the esc’s because when I connect them directly to the rc receiver they both spin.
Does anyone know what the problem could be?
