Experiment with solar energy by building your own helicopter model with solar powered motor! Kit comes complete with pre-cut plywood, assembly instruction manual, solar cell module, small DC motor, 3 foot cable, and sandpaper When the solar cell module is placed in direct sunlight it generates power that is carried through the cable wire to the motor which spins the helicopter's propeller! No soldering is required! Great educational toy that can be placed on display once assembled!
