MMM E-maxx + 9XL on 6s

I ask because thats gonna be my exact setup. when my mmm comes in. I do run a 22pinion but i have a ton of jato spurs so i can gear anyway i want. Im also in the same boat were 6s is realy more than i need. I like to bash in the dirt. But with that said. you can just gear down loosen the sliper, and have the longer runtime. Now if your racing the reduced weight by running 4s might be worth it. All depends on your application. Man i cant wait!!!!
