Hmmm... what pinion gear are you using? Some other pinion gears with the same 2mm 14t spec can be a different diameter and cause the rear drive gear to strip easily. We've designed this car around the pinion gear linked in the description so that we've never had to replace a rear drive gear at all. If you want, you can easily change the tooth count, diameter, and more of our rear drive gear to make it fit better by simply changing a few variables in our public Onshape document. Nice job coming up with that nifty fix though ;) Hope this helps!
