Not entirely sure about the racing at the moment. I do intend to run it at the track on practice days with my 1/10's though, but definitely no bashing.
Originally, I was leaning towards the Savage, but since I do in fact like to tinker, it would end up being a money pitt based on what I've seen.
I'm definitely an Associated guy, but I haven't seen or heard too much about the MGT's.
I've heard nothing but good feedback regarding the Revo.
