Big Rock Pinion gearing 2050kv

[Jsvt289]

Hey guys. Put in a firma 150a with a 2050kv and an 18t pinion. Even on 4s it feels like the truck top end was faster with the stock 3200kv on 15t on 3s. I mostly bash and rip trails but also like high speed runs on soccer fields trying to find the perfect match if possible. Appreciate any suggestions

Yes it is slower.

(3200x15)/18= 2667

This means you need a 2667kv motor with and 18t pinion to get the same top speed on the same amount of lipo cells.

(3200x15)/2050= 23.4

I would start with a 22t pinion and work your way up.
