UGEARS R-5 Airplane engine mechanical wooden model UG70283

The Ugears R-5 is a mechanical wooden 3D model of a classic radial aircraft engine that you assemble yourself. Once built, it is not just a static display piece: its moving parts come to life, showing how the engine's mechanism works in motion.

The valvetrain moves in sync with the rest of the mechanism, and the propeller can be turned via a USB-C power connection. Assembly takes you through the typical structure of a radial engine step by step, and the finished model makes it easy to follow how the components work together.

Inspired by the golden age of aviation, the model suits fans of mechanics, scale models and detailed display objects. It is intended for indoor use and fits well on a desk, shelf or display cabinet.
