Winner of a Dr. Toy Award, this is the remote controlled construction set that uses solar power to propel eight different car designs. The 3 1/2" sq. solar panel can be integrated into a model's design and powers the 3-volt geared motor to send a dragster, motorcycle, or truck in motion. The wired controller enables children to drive their creations forward or backwards at two different speeds. Developed by a team of engineers and educators over three years, the award-winning construction system consists of snap-fit components that attach in three directions, allowing children to easily build simple or complex models with very few parts. The set can also be powered by three AAA batteries (not included) and has 282 pieces with 711 connection points, enabling young engineers to design and build their own creations. Ages 8 and up.
