I really like the Kyosho Rock force. About the only thing wrong with it, is its slow. Not just crawler slow either. Most crawlers will fly past it. But its the biggest 10th scale rig and stands alone with its long chassis and pan hard front suspension. Also it doesn't articulate as much as others but it remains super stable at crazy angles. Here is what kyosho has to say about it.
