Pathfinders - Da Vinci Helicopter
Leonardo da Vinci developed concepts for a giant air screw late in the 15th century. While today's scientists believe the design wouldn't fly, this model is a realistic scaled representation his design. It includes da Vinci gears, a helical sail and a crank. It also integrates well with figurines and can be painted or oiled.
