so i just got done converting my revo to brushless but i keep eating my spur gears....i was thinking of a steal spur gear or should i stick with the plastic ones ?

I would try and figure out the issue first, there has to be a reason for it. If you go to the metal spur you are just masking the problem. A friend did that on his Savage and started going through pinions. I ran the same plastic spur on mine for over a year before I got rid of it, something must be flexing or binding to cause it.

Agreed your either setting mesh to tight or to loose considering everything else is good.

I'll have to agree with everyone else buddy. I ran my stock spur gear in my brushless e maxx and ran stock on my erbe aswell. Plastics grinding to save you from rebuilding your diff gears at $20+
