The brilliant engineer and inventor Leonardo Da Vinci's
sketched flying machines long before the technology or the materials to make
this possible were invented. Today, ROKR brings this vision to life with the
Leonardo da Vinci's Helicopter, a mechanical 3D puzzle that features double
helix wings, a 6-cylinder radial engine, a 2-blade propeller, a steam engine
core, and a conveyor belt-type drive crank, just like how the inventor drew it.
This DIY model is the quintessential steampunk display straight from the
Renaissance, lit up by a red-orange LED light in its furnace and blowing steam
out of its chimney. Build all the models in the Industrial City Series and pay
tribute to man's ingenuity and creativity.
