RE: Isn't it made of steel? hahaha.. *picture now uploaded*
Great advice using the heat shrink, I've done this on the T-maxx and it works till the screws loosen up... Not so easy to do on the Rustler due to the close confines of the inner cup, but I guess it can be done... just happier using the stock plastic axles and they are holding up pretty well to the abuse of the Mamba Maxx and 5700 KV Castle motor...
