i think i better go to market,buy a crab,put in a 9-channel rx,servo,tx..and start crawling.just jokin,hehe.Bro Chun,why dont u build ur own.usually,crawler kaki buys a normal 4x4 mt,with frnt,rear and center diff..then modified to crawler. HPI Wheelie King and TAMIYA Ford highlift are good example,most people using them(ahmo kau).i've seen in the net,sweet action.im thinking to get one too,but not anytime sooner.wedding coming!
