Only available from Hammacher Schlemmer, these are the remote controlled monster trucks children construct and then crash into one another. A head-on collision unseats the drivers and sends them sailing through the air like a live-action stuntman. The two 2.4 GHz dual-throttle remotes let children drive the trucks up to 9 mph and execute sharp hairpin turns from up to 49' away. Comes with two truck chassis, four interchangeable body frames, four drivers, four sticker sheets, and eight cones with flags. A full charge via the included USB cords provides each truck with 30 minutes of power. Each remote requires two AA batteries. Ages 3 and up. 16 1/2" L x 14 1/2" W x 9" D. (5 lbs.)
