The canopy/ support structure is removable, so you can experiment with your own helicopter or wing-type systems. 

The Aerial Screw is one of da Vinci’s most iconic drawings, and defines an artist and inventor well ahead of his time. This working model uses a bevel gear, also from his drawings, to spin the canopy and support structure, illustrating a way Leonardo thought flight might be possible.

The word helicopter is a combination of “HELICO” (spiral) and “PTER” (one with wings).

The kit is easy to assemble, with precut and predrilled pieces that are made from wood farmed in sustainable forests. An illustrated manual is included with history about Leonardo da Vinci.
Glue and ruler are needed (not included). .
