Since I setup my quad with the Pixhawk I've had issues and tried a series of things to rectify it. I've pulled all red wires and taped them up coming from all 4 ESCs. At that point the motors won't arm or spin up. I plugged the Motor 1 red wire back in and all motors arms and spin up as expected. After only a few seconds the one ESC that has its red wire connected heats up to the point of being extremely hot to the touch after no more than 10 seconds of low throttle. In the last setup I tried all combinations of ESCs wiring with all having a red wire connected, 3, 2 1, and none. I'm wondering if I just got a bad Pixhawk as I've tried two different brands of ESCs and getting tired of burning up ESCs and Motors in an effort to get this off the ground.
Any idea what I could be missing? The first round of ESCs had a 5A BEC in all 4 ESCs. The latest setup has 0.5A BEC in all 4 ESCs 30 AMP Afro ESCs. The motors are NTM 28-305 800KV. I know for a fact that the motors have no issues as I've disconnect them and hook them to an ESC/Battery not connected to Pixhawk, the motor runs forever without even getting warm.
Is there some sort of jumper I should be setting up? Is it possible to not run any Positive red wires to the Pixhawk and cut the BEC out complete without running a seperate BEC? I am not running a GPS/Compass and have disabled all Voltage, Current, Compass, and GPS as a result until I can prove this setup works as is.
