Mechanical Stirling Helicopter - Metal Construction Set

Watch heat become flight as you assemble the Mechanical Stirling Helicopter, a remarkable engineering model that transforms thermal energy into spinning rotor motion right before your eyes. Measuring an impressive 39cm long and assembled from over 150 precision components, this stainless steel build combines aviation-inspired design with one of the most fascinating engine concepts ever developed. At the heart of the model is a working Stirling engine system, featuring horizontal piston movement, a rotating flywheel and an external heating chamber that drives the mechanism. As the engine operates, the rotating propeller brings the helicopter to life, creating a captivating demonstration of physics, engineering and motion working together. Supplied with assembly tools, a detailed instruction booklet and a dedicated display stand, the Mechanical Stirling Helicopter delivers a rewarding building experience and a display piece unlike anything else in a collection of conventional aircraft models. Build a machine that turns the power of heat into the illusion of flight.
