So, I've pretty much decided that I want the Summit. I want a new RC, and I honestly can't think of any other model that I'd enjoy more (that I don't already own). So, when I buy this thing what will I need to go with it? What do you suggest as far as batteries are concerned? 4s? 6s? And what sizes fit the battery trays? Can I use the same batteries I have in my ERBE (4300 MAH Lipo hardpacks 2S)? Also, does it need any upgrades out of the box? I plan on just bashing it around my neighborhood mostly..That's just grass, dirt, a bit of sand, and maybe if I get brave I'll drive it through a bit of water. If there are any things that need immediate upgrading, please tell me! With my old slash 4x4 it needed a shock upgrade out of the box!
