I have not seen that problem before Z. But there are only four components in the pusher circuit: the battery, the fire trigger switch, the pusher sensor, and the motor. So let's start by isolating the problem.

I would start with the batteries and motor. Make sure you have fully charged batteries. Run a wire from the positive battery terminal to one side of the pusher motor, and another wire from the negative battery terminal to the other side. If the pusher runs consistently, then we know the problem is in the fire trigger or the sensor. If it runs crappy, then you've either got a bad pusher motor, or a mechanical problem in the pusher assembly.

Get back to us after you run this test and we'll help you figure out the next step.

As far as running the pusher motor on a separate battery, I'm not sure that mod is even necessary. The pusher motor turns a worm gear with a low gear ratio. It takes very little current to run. So while Coop is technically correct, the problem can be simply solved with a battery that supplies a few hundred milliamps more than the combined stall current of the flywheel motors. But hey, I like Rube Goldbergs as much as the next guy 😉
