Default Transmitter ratio?

How do I find my transmiter ratio so I can get my gear ratio?

I think you mean your car's transmission(not transmitter, that's your radio) outdrive ratio, right? If you tell us what car you have, I'm sure one of us will know what it is, so you can accurately figiure your final drive ratios...

if you have trouble finding it from the manufacturer, just do this..

count the front diff pulley teeth... and the divide them with the number of centre pulley teeth... the result will be a internal ratio... to get the final ratio, the formula is spur / pinion x internal ratio.

The Sprint has a 2.13 drive ratio. It is at the top of page 19 of the instruction manual.
