The M5 was originally manufactured in the 1940s and was the first miniature radial engine made for model airplanes. It was designed by Glen Morton and was based on the full-size Velie radial aircraft engine made in 1928. The full-size radial engine was much more powerful and reliable than the old rotary design and was used to power large aircraft such as airliners and World War II-era bombers.
