better planetary gears

[What's_nitro?]

Stampy, I have the same problem with my Rustler. I found I just have to be careful how hard I hit the throttle and the gears last much longer. (go easy on the wheelies!) I've thought about how much stronger a 4-spider, maybe even 6-spider, differential would be versus the planetary setup. Though it would require serious modding as Brian said. I don't know of any spider diff on the market right now that will fit in the Rustler's transmission case.
