Wooden 3D puzzle "R-5 aircraft engine"

The wooden 3D model "R-5 Aircraft Engine" is a true engineering masterpiece for lovers of aviation, complex modelling, and mechanical beauty. The model recreates the iconic five-cylinder radial engine developed by the American company Kinner Airplane & Motor Corporation in 1935. These air-cooled radial engines powered training aircraft of the 1930s and World War II, training a whole generation of pilots.

This designer gives you a rare opportunity not only to assemble an aesthetic model, but also to visually understand how a real aircraft engine functions from the inside. Thanks to the open design, you can observe the synchronous operation of the crankshaft, metal pushrods, compression springs and gears.

Mechanics and technology:

– Live rhythm: the model is equipped with an electric motor powered via a USB-C cable, a control board in the base, and a convenient switch on the stand.

– Historical accuracy: the five pistons move in the real ignition sequence of radial engines - 1-3-5-2-4, and the gas distribution mechanism operates in perfect synchronisation with each cylinder.

– Safety and detailing: The milled screw is equipped with a safety disconnect mechanism that gently stops rotation upon contact with an obstacle, protecting the model and hands while working.

– Glue-free assembly: All 470 parts are cut with high precision and fit together without the use of glue or special tools.

Technical specifications:

– Number of parts: 470 pcs.

– Difficulty level: high (complex modelling)

– Assembled model size: 8.7" x 9.6" x 5.7"

– Package size: 14.7" x 6.7" x 1.4"

– Materials: natural wood, metal, electronic components

– Package contents: assembly parts, electric motor, USB-C connector, step-by-step instructions in 11 languages

This designer will be an unforgettable gift for engineers, aviation fans and everyone who loves to feel the pleasure of creating complex mechanisms with their own hands. The assembled model will not only decorate your desktop or interior, but will also become a visual working exhibit of the history of aeronautics.
