The std novak motors are kinda small, like 380 internal size. Not much power, I tried the 13.5 on 3s with a MM in a pede and could not gear it low enough to run cool. Even a feigao 540 12s was better.

Stick with the hv novaks for a 4wd slash. The smaller motors are ok for youring cars and 10th 2wd buggies. Otherwise they do not have enough torque and also get very hot.
