Not impressed with RC-M pinions

[Unsullied_Spy]

I purchased a 13 tooth RC-M hardened steel pinion gear for my BL Muggy and with only ~3 hours of use on it it started making a strange noise. I looked at the pinion and it's already almost worn out! I plan to flip it over and use the part that doesn't make contact with my spur until I can get my RRP Xtra hard and Novak hardened gears to replace them (going to test and see who's gears last the best). It was a good gear as far as meshing properly and not totally failing on me, but I am disappointed at how quickly it wore out.
