Leonardo Da Vinci's Helicopter

ROKR CGL01 Leonardo da Vinci's Helicopter Mechanical 3D Puzzle Note: Model Kit Assembly Required The brilliant engineer and inventor Leonardo Da Vinci sketched flying machines long before the technology or the materials to make this possible were invented. Today, ROKR brings this vision to life with 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 as the inventor drew it. This DIY model is the quintessential steampunk display straight from the Renaissance, lit by a red-orange LED in its furnace and blowing steam from its chimney. Build all the models in the Industrial City Series and pay tribute to man's ingenuity and creativity.
