Not impressed with RC-M pinions

[jhautz]

Ummm... I think the RRP and the RCM pinions are identicle parts. If one is giving you trouble the other will lily give you trouble too. I have tried one novak 1/8 pinion and it did wear on me after only a few race days so I dont think they are even as hard as the RCM and RRP gears. I have never had an issue with the RCM or RRP pinions. Sounds to me like there may some setup issues that needs to be looked at. Is the motor mount bent or anyhting that could cause the gear mesh to not run perfectly true. Or possible something flexing on hard landings that causes gear mesh issues. This was the only time I ever wore a RCM hardened pinion. My motor mount screws poped the heads off and the centerdiff mount and motor mount was loose and causing all kinds of flex. When I noticed the problem after the run I also saw that I wore the pinion gear pretty good from the mesh flexing around.


EDIT: All that said, The smaller pinion gears like the 12 and 13T will have more trouble than the larger gears. On the smaller gears the angle of the teeth is greeater and the mesh is less ideal and can cause additiona stress and wear.
