what is a good start for gearing?
I'm setting up my sons tc5 we just picked up used, with a 21.5 spec motor and using a XP SC450-BL esc borrowed from his T4.1 RTR. I added a 25t pinion and used 86t spur the car came with and the car seems extremely slow. I do not want to over gear the car, I want to make it fast enough for him to enjoy. Could someone give me a decent starting point.
We are both new to our tc5's so any help would be appreciated.
