Hi,
I recently damaged the pinion gear for a stepper motor that came with the mclennan gearboxes and am looking at replacing it, but how do I identify the pitch?
I went to an RC hobby shop and they had similar pinions but not the same size.
i'm sure smallparts would have these but not sure how to narrow it down.
this was the gearbox/motor combo.
