...this would only work - that is using the smaller circuit board from the dual motored engines - if you wire all the motors in series.
Ohm's Law. The load on the reverse unit will be about the same as a single factory wired 2 motor A unit and the set won't run at rocket-like speeds at 6 volts when each unit has series-wired motors.
