Yes, that is the recommended method. See the latest revision of the electrical drawing and the Tips & Guidelines. It also minimizes the voltage losses to the RC due to the high currents of the motors passing through the smaller fuse panel. I know this is hard to visualize but the current provided to a motor (speed controller power in) and the current returning from the motor is the same. Since a Chalupa motor stalls at a over 100 amps, that current is flowing through both the red and black wire. For every foot of #10 (black or red)that equates to a 0.1 volt drop.
