Have hours of fun constructing this amazing Leonardo da Vinci wooden helicopter.
Leonardo da Vinci developed concepts for a giant air screw late in the 15th century.
This working model uses a bevel gear, also from his drawings, to spin the canopy and support structure, illustrating the way Leonardo thought flight might be possible.
A fun and inspiring project from one of the greatest minds of history.
Easy to make from pre-cut and pre-drilled sustainable timber.
Size: assembled, 38 x 23 cm; box, 25.5 x19 x5.5 cm
