gearing tip ?
 

Hi !


what gearing will work with a feiago 8xl/mm combo in a inferno st us truggy with 46t spur on 4s fp pack ?

Use the parameter solver link in the R/C calculations (in sig). Just enter your desired speed, spur, diff, V, etc, but leave the pinion blank. It will calculate the needed pinion to get that speed...

yes iknow :) but how will i know that my motor/mm esc can handle that gearing ?

Well, what are you shooting for speed-wise? And what is the approximate weight?

Truggies have larger tires, which is like adding a tooth or two. And since you're running a 46T spur, that makes for fairly tall gearing for a truggy. So, I'd start with 12-13T pinion and see how things go. Watch temps and adjust accordingly.
