In 1986 was developed aircraft engine AT-714 which is based on automobile engine cylinders from Tatra 613.
Since the beginning, the engine was intended for ultralight airplanes, especially XL-113.
Nowadays, the original engine is shown in the Tatra Museum of Technology in Kopřivnice.
Production of the engine moved from Kopřivnice to Prague, where Mr. Tomášek continued in development of the engine under name Alfa-Prag.
Since 2007 is development and production of the engine in our company, where we focus on keeping the engine up-to-date and enhancing its already good properties.
