Assemble me. Let your imagination soar to the sky! In 1489, the greatest polymath the world has ever known sketched a design for an “aerial screw" or helical rotor. Da Vinci's dream of mechanical flight was not only the earliest conception of a helicopter but gave birth to the entire field of aeronautics. The world would have to wait until the early 20th century before the first machines capable of lifting off the ground were invented, paving the way to today's helicopters—aircraft capable of vertical take-off and landing, hovering in the air, and forward, backward, and lateral flight. The Ugears Mini Helicopter is loaded with realistic details including a turning rotor mast and main rotor, turning tail rotor, twin seater cockpit with cyclic stick controls, doors that open, adjustable searchlight in front, retractable rear wheels, landing skids and a helipad on which to rest your model. To set your Ugears Mini Helicopter in motion set the Start/Stop switch to the "Stop" position, give several twists to the silent ratchet key to wind the rubber band motor, put the rear wheels down, set the model on a flat surface, then gently hold the model as you flip the switch to "Start," release and watch as your 3D puzzle helicopter runs ahead for about 1.5 m.
