Yeah with all the plastic parts and softer (high traction) arms the Cyclone S handles very well on asphalt. It is a little heavy though (but you cant have it all :P)
Ive also had the post on the diff halves which the pulley sits on snap a couple of times. Its probably more suited to stock and 540 racing. If you find the diff keeps undoing itself every run, then the post has probably snapped off.
