ENGINE, SAITO FG-21 4C, GAS, ELEC. IGN.+
The Saito FG petrol engine is a four-stroke power plant
Overview
The wildly innovative FG-21 brings Saito’s unmatched reputation for quality and dependability in the four-stroke glow market to gas enthusiasts everywhere. Based on the lightest 1.20-size engine available, it is the perfect choice for all .60- to 1.20-size aircraft.
Perhaps the most amazing detail about this unique powerhouse is the first purpose-designed gasoline carburetor for model engines. Lighter and smaller than other industrial carb designs, it operates with the same ease you have come to expect and its size allows the engine to be conveniently dropped into most airframes.
The impeccable workmanship of the FG-21 results in tremendous operation that can decrease your operating costs by up to 90%*. It also has enough power to swing a 15” x 7” three-bladed prop.
By combining the reliability of gas with the sweet sound of Saito, advanced technology and foresight are once again helping Saito lead the way into the future
