I've got some newb lipo Q's for you guys

[Sammus]

I reckon if your going to run MMM then run 6s :) if you get decent capacity packs they should be plenty, and you can even get 2x 3s packs and have them on either side of the truck, hooked up in series. Thats what I'm doing anyway, I have two 3s 4000mah 20C packs I'll run as a 6s in my revo and reckon it'll be plenty. time will tell I guess :)
