Robinson Racing Steel 48P Pinion Gear (3.17mm Bore) (12T)

garbage the gears dont last. to soft of metal.garbage

Upgraded my Yeti Jr to brushless and needed a new pinion for the different size motor shaft. Tried out the the 15T and the wheel speed was a little too high so I bumped down to a 12T. I always trust Robinson Racing to make high quality parts.

I've always relied on Robinson Racing to make the best high strength pinion and spur gears and this is no exception. Fit and meshed nicely. Now I just wish they made a spur gear for the Yeti Jr. Unfortunately it doesn't appear that anyone does but the stock plastic Axial one. Needed a new pinion gear when I upgraded to brushless because of a different size motor shaft. I've never had any issues with Robinson Racing parts in the past so it was an easy decision.

Works great on my Kyosho Fazer. Ran a couple 3s packs through it with no obvious sighns of wear. The Nickel plating is holding up nicely. Should hold up pretty well when used with a plastic spur gear. I do wish A-main stocked these in the hardened steel version from Robinson though.

Great product as always from Robinson Racing. This pinion looks like I will last forever!

i had this pinion on my rustler 2wd vxl on the store motor mesh was set perfectly and i went up a road 20ft and the pinion was gone chewed to pieces i went slow didn't exceed 20mph.
