Ugears R-5 Aircraft Engine

Ugears R-5 Aircraft Engine – working wooden radial engine

Build an aircraft engine that actually runs! The R-5 Aircraft Engine is a working model of a five-cylinder radial engine in 470 parts, based on the Kinner R-5, which was certified in the USA in 1935 and powered training aircraft through the 1930s and the Second World War.

The engine is driven by an electric motor powered via USB-C – the switch sits in the base, and the control board is built into the stand. The five pistons follow the correct firing order 1-3-5-2-4 with a synchronised valve mechanism, metal pushrods and compression springs. The milled propeller has a safety release that disengages when it meets resistance. With wood, metal and electronics and fully visible mechanics, it is also ideal for teaching.
