But seriously though, that Traxxas will never be able to hold it down at the track. Sorry. And trying to redesign the Bandit (while I'm sure it would be interesting for us to see you try) is simply a bad idea.
The GV2 - now that's a good looking ride. Racer blood built with some basher-friendly features.
Good luck, just get the GV2
