speaking of gearing and what not, how do you factor gear ratios? and what are the stock gears and gear ratio on a team built rc10gt (few years old)? i have a o.s. .12 cvx that needs a rebuild so i'm using that as an excuse to get a new engine. i'd like to get a fantom fr12 or somthing of that nature. at the very least i'm getting a .12 cv-r. and seeing as how my current engine would reach top speed in 3-5 seconds i want to re-gear it. any suggestions?


oh yeah. and whats one of the most powerful .12 engines that will bolt up to my rc10?
