Szekely SR-3

Szekely aircraft engines were three-cylinder radial engines built in Holland, Michigan in the 1920s and 30s. They were used to power small aircraft such as the Rearwin Junior, Taylor H-2 and American Eagle Eaglet. Often criticized for reliability issues and design flaws many were replaced with better engines in their original airframes. Few examples still exist but a museum quality example is on display in the Holland Museum in Holland, Michigan.
