Engineering skills hit the fast track with this amazing construct-a-machine kit. Kids will explore the physics of speed, acceleration, energy and aerodynamics as they build and experiment with ten different mobile creations including a high-speed race car, an off-road buggy and a semi-trailer truck. The transmission inside the gearbox has four gears that can be easily rearranged to optimize speed or torque, and the IR remote control unit drives the cars forward or backward and steers left and right. Cool-looking auto body plates give the models a realistic appearance, and decals allow builders to customize their cars. Includes 252 pieces and a 64-page full-color, step-by-step illustrated construction manual. Uses two AAA and three AA batteries (sold separately).
Age Recommendation: Ages 8 and up
