Another spur gear chewed up The mesh doesn't seem to be too tight, I can just slightly still rock the gears back and forth. I've done several builds and installed many pinions trouble free, so I'm kind of at a loss here. I'm thinking there's too much gearing/torque for the stock plastic spur. This is a BR3S with 18t pinion and a 3674 2400kv motor on 3S...this is a far cry from what the factory spur is meant to handle. I'm starting to think the spur just can't take the power. Next step is try a metal spur..
