Set the mesh right and it won't be a problem. just loose enough so there is a little play and it rolls nicely. Also imo, cut the 60t spur gear cover open on the bottom of the chassis. All of the strped spur gear problems I had were due to rocks and junk getting traped in that cover. Since I've completely opened the spur gear up I've not had any more problems. Just something to try if you have spur gear problems.

also the Tekin mini rage.. I'd stay away from it. I've read several people having problems with the controllers not being the best. They are not up to par with the controller software Vs Mamba and Quark controllers.
