Winner of an ASTRA Best Toys For Kids award, this is the construction set that lets young engineers design their own remote-controlled machines. The 182 snap-together pieces come with instructions to build 10 different vehicles and machines, such as a bulldozer, crane, Formula One racer, robotic arm, and even an antique car. All vehicles are powered using one or more of three included remote-controlled motors for basic forward and reverse movement; the crane even employs all three for rolling, rotating, and raising and lowering the arm. Children can control all three motors at once with the easy-to-operate infrared remote. A 48-page color instruction book illustrates step-by-step instructions for building each model, though children can always invent designs from their own imagination. Requires 5 AA batteries. Ages 8 and up. 15" H x 12" W x 3" D. (3 lbs.)
