RE: Updated: Mad Torque!!!
Thanks!!! it is tough to find stuff it can't crawl over, but the steeper rocks seemed to make it roll backwards, until i stretched it, it seems to hold up just fine on the rocks for the most part, the pinion gear's set screw came loose but easy fix. Those Sumo's look pretty neat, i'd like one for indoor use in the winter. Just ordered a Jeep Wrangler body for it because the wheel base is longer so maybe it will stop grinding the wheels.
