i have done this same set up... in a g3r revo


my exp. was this, on 4s it cogged, it was still usable but not track worthy, the esc. also ran a little hot, caused by the cogging (???)

in my crt .5 on 3s it cogged very little and was way fast and powerfull, but it is very light compared to a mt

what is your setup???

if using a stock chassis and 2spd revo trans (requires a servo for brakes) it should be better because of the lower gearing of 1st gear

but i am not quite sure i would recomend this setup, you could try it, but if you need to buy the parts..... its up to you
