This is the 797-piece rollercoaster that rises to 7'-high and automatically launches its single car with a motorized accelerator. Snapped together easily by young architects into trusses, towers, twists, and turns using the color-coded instruction booklet, the coaster includes over 24' of track and can be configured into one of two models that provide both vertical thrills and curvy chills. The coaster’s car begins its journey when two spinning flywheels grab it and launch it up a straight track section with enough momentum to clear the apex. Gravity and momentum take over, carrying the car through a twisting corkscrew, loop, and banked curve that leads right back to the launcher in a continuous looping thrill ride. Requires three C batteries. Ages 9 and up. 84" H x 21" W x 12" D. (5 lbs.)
