The Walter M601 is a turboprop aircraft engine produced by Walter Aircraft Engines of the Czech Republic. The company's first turboprop, the M601 is used in business, agricultural and military training aircraft.
Development
The turboprop was designed for use on the Let L-410 and the M601 first ran in 1967. It was not suitable for the prototype L-410 and the company developed an upgraded version, the M601A, with a slightly wider diameter.
