Hey guys im sure you heard this over and over again but i couldnt find the answer i was looking for. I would like to get an idea on gearing. I bought the rtr version and now i am going to upgrade motor and esc. I am going with the tekin RX8 esc and the Pro 4 4600KV motor. I am running the mip chassis so i am lighter than stock. I only race and its generally on a medium sized 1/8th outdoor track (but we shorten it for the short course trucks). I would like to know where to start with pinion size. Im fairly new to electrics so i hope this dosent sound too stupid. Im pretty sure the gears are 32pitch, correct me if im wrong. If some one could please give me an idea where to start as far as the pinion goes and if there is any certain brand pinion. Also is there any thing different i will have to do to go with the Pro 4 as i understand it is a 540 motor and the stock is a 550? Thank you.
