Leonardo da Vinci’s helicopter is a world renowned example of his ability to think centuries ahead of his time. The design of this helicopter was drawn in 1493, 450 years earlier than an actual helicopter would take to the air. Leonardo’s invention for the Helicopter was most likely conceptualized while he was either studying or examining the seeds of the Maple Tree. He could also have been inspired by Archimedes. Leonardo’s helicopter was designed as a human powered machine. Unfortunately for Leonardo, engines had not been invented yet and humans have nowhere near the power to weight ratio required for them to produce enough energy to lift themselves against the force of gravity.
This build presents a Lego variant of the machine. The center axle, and the "rotor" can spin, so you can play with it, fully functional.
Note: some rope elements are missing from LDD.
