well after going threw my first set of brushes in no time on my tekin fxr 35t motor combo im looking into options to help my brushes last longer. First off i know dropping from my current 11.1v setup down to a 7.4 would make a difference. but i don't want to do that. ive heard of people using mesh over thier motors but i hit alot of mud and cant see that helping once i pack it full. lol anyone on here ever try it? been thinking maybe trying to build a floor pan or buying one then modding it to cover the motor as well but again im in the mud allot. id have to make it perfect. anyone have any better or easier ideas. id like to hear what others have done. i know 100% sealed is a bad idea and i don't mind water still getting in. and on another note. anyone have a way to smooth out the comm without a lathe mine looks like a brush grinder.
