KOP gearboxes and FisherPrice Motors

Is there a way to attach a fisherprice motor to the gearbox from the KOP? Or is there a simple way to attach the fisherprice gearbox to the KOP gearbox?

If you have the time, the easiest and cleanest way to do it.

Would be to buy this:


This is a FP planetary which has the same mounting holes as a CIM, so it would mount to the Toughbox super easy.


Not directly.

Try an AndyMark Planetary gearbox; it’ll slow the FP down a bit, but should do the trick.

Or you could make an octagonal FP gearbox-shaft coupling and use that to drive the Toughbox.
