    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.

    here are a couple pics of my home styled inner fender and mud guards. they worked out beautifully. no noticeable mud or debris anywhere near the motor.

    made from a single 2litre pop bottle.

    and a clear guard under the motor and over the drive shaft. worked out perfectly. :) ignore the dirt and whatnot. this was after the first test run.

    I just rebuild the motor.. a Green scouring pad cleans the comm and I just buy brushes in bulk lol..
    So far with the Integy motor I have not had to do squat.. If I play in the mud.. I just run it through a stream of water before bringing it home for servicing.

    ive actually been thrue 6 motors in my honcho. i think its because i run 3 cell lipo. the last one was a lepord hobby 35t. the comm on it became uneven. it was fine at low speed but at high speed the brushes lost contact.
    wish i could find a cheap motor lathe to true the com's. its just not realistic to spend $200 on a tool to fix a $27 motor.
