These Dangun Racers are models of the cars used to break the land-speed record. Each kit is motorized and comes with several gears and an axle you assemble into a working motor system yourself. The actual motor comes pre-built. From Tamiya.Jet engine style, GRID-KING is introduced to DANGUN RACERS SERIES, known for its side-by-side, aggressive action. The smooth argentine body has been designed with maximum aerodynamics to minimize wind resistance. Huge air-intake and exhaust are just like the parts found on the full-sized Record Breaker cars racing in the Utah Salt Flats. Skid roller precisely controls the machine while rear wheel drives acceleration. This is the one that will put you in the lead on the DANGUN CIRCUIT!
