seth556-- Great choice! XXX-T, Mamba 5700, 3s lipo.

I have the same setup and it rocks! I currently am using a MaxAmps 3s2p 6000mah lipo. I melted a diff gear just like that a couple of weeks back. When you rebuild your diff run it totally locked and put a drop of blule locktite on the nut to keep it from backing off. I love the lipo on the street but swap it out for a 6 cell IB4200 pack in the dirt. I just don't have any fun with the lipo spinning out left and right. After reading about the new MaxAmps 5000 packs I am thinking of getting a 2s version for the dirt. I have clocked mine using GPS at 57mph on the street. Here are a couple of pics of my setup.
