Yeah, that's a race roller. I love mine. I bought it from a guy I knew basically because the radio was worth almost what I paid for the whole shooting match. Never was really much of a truggy guy, but I took it apart, rebuilt and set it up and took it to the track and found out it was a blast to drive. The Truhe 2007 Nitro Challenge setup is a good base. If you don't have it already, be sure you download the throttle addendum on the Losi site and follow it when you set up your linkage. It will save you blown servos. There's also a radio tray addendum where you put o-rings under the radio tray, but I never have and mine has been fine.
