hi, i own a red cat tornado bb. everything on it is stock, except i upgraded to a starter plate instead of a pullcord. the machine runs awsome, i just have a major issue of stripping the plastic first gear spur gear. i've been through 6 in two days. i know this is a common issue, but i was wondering what the best fix is? i was also wondering if there are any compatible transmissions with metal spur gears? idc if it's a single or a double speed, i'm not very concerned about the top end speed. i have looked all over the web and i can't find a single compatible metal gear. can anyone help me, or even get me in the right direction? it'd be much apreciated..
