wow guys, thanks for all the help so far. i am going to order the 5mm bore, Mod1 pinion with the 46t Kyosho spur. a few of each. we will start from there and hope things work out.

yes i know this is dirty. i had it at the track 2 days before i just brought it back and haven't cleaned it. although when i first got it, i took it all apart and cleaned everything. looked beautiful. but once i got to the track it was back dirty again within 5 seconds. obviously.

how do you keep everything so clean? do you completely tear everything down after each run? forgive my thoughts, but thats seems a bit much to have to clean every time you run.
