This is the motorized construction set that enables young engineers to build a working remote-control truck that dances to pre-loaded music. It’s constructed from 179 pieces including stainless steel plates, screws, and nuts. The included five channel remote control sends the truck forward, backward, and flips the front axle a full 360º for creative stunts. A top button on the remote engages its pre-loaded songs and activates the truck’s dancing mode. With color-changing blue, green, and red LEDs on the front, sides, and cockpit. Requires four AAA batteries and two AA batteries. Ages 8 and up. 6" L x 5 1/2" W x 4 1/2" H. (1 lb.)
