Need Help Gearing a TC3 to run a 17.5brushless
I've recently stared running cars at my local hobby shop. They run a vintage trans am class with 17.5 brushless motors on 6cell nimh. I bought a used TC3and need help with the gearing. The gearing charts say the optimal gearing is 3.5:1. The closet I can get is a 69Tspur with a 49T pinion. There is no way that gearing combination will fit in the chassis. Can anyone help me out?
