Saito FG21 is a 4-stroke gasoline engine exclusively for model airplanes which is designed with emphasis on high performance, durability and weight saving. This engine is modified based on existing FG- 20 gasoline engine, equipped with renewed ignition system. For the airplane on which FA- 125 is installed, FG-21 can be replaced easily with minimal change such as fuel tank and lines to gasoline-resistant ones.
