O.S. GF40 4-Takts Bensin Flygmotor
Introducing a gasoline 4-stroke 40cc engine that is attractive for performance, sound, and looks. In addition to the 2-stroke GT series that was released earlier, the birth of the new 4-stroke series "GF" series has been developed so that it can be enjoyed not only by scale fans but also by category. The appearance is a design concept that tickles the hearts of modelers who love mechanics. Around the push rod, the latest OS 4-stroke design taste is inherited. The rocker cover has revived the teardrop type design, which was also the image of the OS 4-cycle engine.The mount size and the distance to the drive washer are the same size as the 2-cycle GT33, and it can be easily replaced. The attached F-6040 silencer is not only sound deadening, but also the exhaust note that seems to be a 4-cycle engine is one of the attractions. The specially developed Walbro carburetor has achieved quick response while emphasizing easy-to-use performance. A 4-stroke power feel designed exclusively for gasoline from scratch and a sound full of realism. And excellent fuel efficiency. Please experience the charm of the 4-cycle gasoline engine.
