Leonardo Da Vinci Helicopter

Leonardo's Aerial Screw was designed to use the power of four men to push the canopy and outer ring to make this model fly. The idea of this flying contraption was way ahead of its time!

A great beginners model with only 19 pieces. Everything required is included.

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

Recommended age 9 and up.
Assembled dimensions: 38cm x 23cm x 23cm
