awesome responses! thanks guys. our track is pretty much all nitro as far as truggies go so ill fit right in........and i think i can pretty much always have my buddy do my pitting. either way i can get someone to do it at the track........i know im not gonna be able to replace my motor every season(just cost me to much) but i am pretty good about maintaining my stuff so hopefully i can stretch they're life.......thanks again..........and if anything else comes to mind, please post it
