Leonardo Da Vinci The Marvellous Machines - Elicottero Helicopter

* Model kit comes unpainted and unassembled.

This machine, which is considered the ancestor of the modern helicopter, appears in a drawing dated roughly 1480 contained in the Codex Atlantics. Leonardo outlines the plan for an "aerial screw" imagining it as a worm screw with a diameter of approximately 5 metres, in his intentions, it should have "screwed itself" in air taking advantage of its density. Moved by the muscle strength of four men walking on the central platform, it consisted of a wooden structure covered with starched linen cloth. Since there is no proof that Leonardo actually built the machine he imagined, it remains one of his many the orifical insights.
