DA VINCI HELICOPTER Battery Holders Coercitivity: 860 - 915 kA/mLeonardo 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.
