The gears need to be shimmed properly for gear lash. I've raced this chassis indoor carpet and have hit hard rails with it without fully destroying the gears. I run one at the Tamiya track a few times a year and have broken the tip of a tooth on either gear, but have never fully stripped a set. It's just shimming to minimize gear lash. I replace the rear gear sets more often on my cars it seems.
