The O.S. GF 40 combines the user-friendliness and efficiency of a traditional 4-stroke engine with a gasoline engine. Its quick and powerful response is ideal for scale, sport, and aerobatic models. The mounting points are identical to those of the GT 33 2-stroke engine. The carburetor was developed by O.S. in collaboration with Walbro® specifically for this engine.
