Hmm ... don't want to be picky ... seems that i'm the only one who "killed" a rcmonster hardenend pinion (it lasted for 20 runs in a 11lbs Truggy, Neu 1515/2Y with 10s1p A123). I ordered mine 2 months ago. I now use a cut off clutchbell pinion with the same steel spur. I related the excessive wear to motor mount flex.
