    I have an RC 10 B4 RTR. It comes with a 17 turn motor, but I added a modified 17 turn motor. I cant go to a lower turn motor unless I change the electronic speed control, which I dont want to do. I am looking to increase speed through gearing. What is the lowest gear ratio that I can achieve that will fit on my car without changing the transmission? Please tell me the number of teeth on the pinion and spur gears. I am looking to get the gear ratio as close to 6 as possible.

    with my 4tec I was running a 29 tooth pinon and a 69 tooth spur and it went good. I don't know if that would work on there or not tho. Welcome to the board. Im sure there will be someone elese with better gears :D

    If your just looking for top end then bump the pinion gear up a couple of teeth, mind you that the youll loose some low end and dont over gear much more or you stand the chance of cooking your motor, RED
