Most guys here will be for the hyper 7, and its a great buggy.

I've got a 9.5 upgraded to pro specs, complete racing set-up. I'm selling if you're interested, send a pm. The hyper 7 might make a better racer, but i'm not really sure since i've never driven one personally. All i can vouch for is my own set-up, and it hauls and corners on rails, lots of fun to drive but i have no-one to race with and my track is too small anyway.
