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.
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.
