Doesn't look to me like the red wire on the ESC would pass any current other than to power the ESC and the BEC. All the current from the positive pole of the battery to the positive pole of the motor passes direct.
So if I run a heavy wire from the two positives (motor and battery to each other) and heavy wire from the negative leads of the ESC to battery neg and motor negative, the red wire on the esc only needs to be of a smaller diameter. It doesn't power the motor.
I'm just trying to work with the way the esc is currently wired. Two heavy black and green leads, and one lighter red.
