Mike, that was an old picture of the motor/mount. I just wanted to show the spacing needed to clear the Kyosho brakes. In another post you mentioned that bracing the motor at the rear would cause problems when the chassis flexes. I agreed with you and removed the rear brace before the truggy was ever run. So the stripped pinion must be due to some other problem. I find it hard to believe 75% motor brake could shear off metal teeth like that. I only have this kind of problem with my truggies (Kyosho ST-RR and CEN TR), I have stripped a few plastic spurs but only this one pinion. My buggy has not suffered from this type of problem. I appreciate all the feedback.
