OS FS 60 open rocker engine was the first 4 stroke engine, which Ogawa Seisakusho Company (well known, as O.S.), was developed and introduced in far 1976 year. This 47 years engine, of coarse, looks old fashioned and ancient, but this engine becomes a predecessor of a new era, the era of 4 stroke RC engines and open a new industry perspective. In my cycle of a 50-60 class engines comparison test run this OF FS 60 of course, could not becomes a winner. But to pay tribe to this engine I decide to include it in this test run. Interesting, how it will perform in comparison with more contemporary brothers in arms.
Of course, to make test results comparable, only one test prop will be used, MAS 13x6 and all engines will run on standard FAI fuel.
Thank you for watching and have a nice day !
