Toy helicopter, which is characterized because on both sides of its lightweight structure consists of wheels that are also the load elements of the friction mechanism rope that drives the toy and on whose axis, of this pair of wheels, they are mounted inside the structure, protected by two side plates of transparent plastic, a gear wheel that meshes with a pinion arranged on an axis parallel to and above the previous one, which in turn involves a cogwheel gear that meshes on a pinion, located at the lower end of a vertical metal shaft that is conveniently protected by thin sheets of plastic ends at the other end, constituting itself as an axis of rotation joined with a very light paddlewheel, whose inclination allows the rise of the totality of the toy, whose low weight and power of the friction mechanism can reach great heights.
