So first problem is how to drive two boards from one throttle signal .............
Hi Jackbauer
Sharing the 3 bus bars I think will not be the a great idea. Now having a common bat/motor + and bat- and individual motor - to each motor, will be the right approach.
Driving the control boards: I would use a single, above 5K and below 10K pot throttle signal to drive both boards together .
