ROKR Leonardo da Vinci's Helicopter Mechanical 3D Puzzle, ROECGL01

ROKR Leonardo da Vinci's Helicopter Mechanical 3D Puzzle, ROECGL01 Be inspired to invent and create with the ROKR Leonardo da Vinci's Helicopter, a DIY puzzle kit based on the genius's 15th-century ideas of a flying machine. 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. Sturdy Steam Punk Construction The main body of the beetle is made of ABS polymer structure material with good impact resistance. Along with the brass and black color palette, this results in a sturdy steampunk-style construction that's befitting its mechanized theme. Features: - Leonardo da Vinci's Visionary Designs: The great 15th-century inventor already knew that one day, machines like the double helix wings would enable man to fly. - Synchronized Industrial City: All DIY puzzle models of the Industrial City can be switched on simultaneously via a wireless receiver or electric track connection. - 3-Part Mechanics: This model features a differential pressure furnace, a chimney, and a six-cylinder radial engine, depicting how steam and heat energy work together to power early industrial machines. - The Helicopter's Mechanics: The 6-cylinder engine's pistons spin the wings, creating lift, and generating movement with the help of wind pushed by the 2-blade propeller. - Communication and Monitoring: The Leonardo da Vinci's Helicopter is equipped with a mini exploration radar to monitor its movements and communicate with the team on the ground. - Coming Through: The model also has a warning system in the form of an air horn to alert people of the craft's presence. - Drive Crank Transmission System: This is the industrial conveyor that keeps the machine's gears working in sync. Notes: Connectors are sold separately. You need to prepare the Type-C power cable by yourself.
