I'm currently running mid motor with the +11mm Exotek chassis. I like it because that means I can keep running my Finisher body which was is my favorite body right now. I actually cut it for the shorter chassis but it fits ok on the longer setup....
I think when I get a new 210v2 I will keep this as a rear motor roller or set it up for my girlfriend to try. I'm really hoping to get her hooked on RC

Perhaps I should get her a truck to drive first since they are usually easier...
