Heating these isn't going to budge them, I've tried.

When the front bearing and crank are out, there really isn't enough of an edge to catch on that inner race to tap it out, either. There isn't much difference in the bearing race ID and the hole in the crankcase, so there isn't much to attempt to snag.

I know OFNA makes pullers for RC car engine bearings - anyone ever used one? I see the kit for the .12 and .15 engines has a 10 and an 11 mm puller.
