The revo gear will fir but will be too small and require a tiny pinion


Depend, if the revo 40 tooth mod1 is the same diameter than the stock stampede 84 tooth 48 pitch, no prob for gearing, with a mod1 13 tooths pinion, it's suppose to be not to bad?? I'am wrong???
I've did the test on R/C calculation and this is what i've experience.
