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. Finished model size is 38cm high by 23 cm wide.
