Default RE: I want to go faster!! (TC4 & Mamba 5700K)

This is funny... I just came back from running my car and i too was looking for more speed. i also have the TC4 factory team

originally, i was running the mamba 5700 with a 2s 5400 lipo with 72/20 gearing and the car was fast.
I then put in the mamba 7700 motor with the same setup and the car was #*#*ing fast

Last night, i installed an 81 tooth Spur( which is the largest that will fit, and still needs a little dremmel work)
and an 18 pinion.. with a 3s 4000 lipo and back to the 5700 motor as instructed by Castle.

I find the car slower..yet they state this should be the fastest setup.

So i am in the same boat...although I have never figured How to analyze the gearing ratios.

What is the math equasion??
