Getting Back into Brushless, heres what I'm startin with

This buggy would be raced mainly on an indoor offroad track Bumps N Jumps if any of you are from the NJ/PA/DE/NY/MD area may have heard of it. Not many long straights lots of technical stuff lots of on/off throttle not many straights so real high current draws and hard on esc for up to 30min A mains. Its a super slick clay track where everyone runs rubber slicks all around tons of traction and about a 50' long straight max. But I would also like this buggy for bashing so something alittle flexible might be nice with alittle more speed than needed for that track.
