Wind Turbine 72pcs

This kit will help children explore the power of wind and store the produced energy to activate the four models they can build with this set; electric car, airplane, helicopter and truck. The wind power is converted into mechanical power from the big gears in the kit and to electrical power via the gear motor that acts as a dynamo. The power is then stored in a rechargeable battery found in the smart battery box unit. Highly efficient aerodynamic and adjustable 3 blade propeller to fit all wind conditions. Requires 1 AA/LR6 battery or a rechargeable battery – not included. Ages 8yrs+.
