KNEX COBRA CURSE ROLLER COASTER BUILDING SET

From K'NEX. This all-new thrill ride building set combines motorized roller coaster excitement with exhilarating head-to-head racing! Color-coded instructions help you build this intense track up to 3.5 feet tall. When you've finished building, simply switch on the motor to bring the model to life. Watch in excitement as the 2 cars are quickly brought to the top by the included motorized chain lift. After cresting, both cars speed away, racing through twists, turns and loops in a race to the finish. For even more excitement, you can rebuild the model and try racing on a second dynamic track with instructions from the K'Nex website. Set includes 1,100 colorful K'Nex pieces, motor, 2 coaster cars and over 32" of track.
