I run mine with the truggy chassis 'cause I mainly drive on the local 8th scale dirt track where I don't want back flips. It floats over bumps and jumps and it's fun to watch other cars get out of the way when they hear this monster coming (I use a steel spur gear - sounds like a jet engine when I stomp the throttle).

But just know that it's hard to find a monster truck body that fits the truggy chassis. The Tekno web page lists them, but the HPI bodies are almost never in stock anywhere. The Associated Rival body works well when you can find one in stock. I think Amain may still have 'em.
