O.S. engines are well-known for their excellent quality, reliability, and ease-of-use. Recently, O.S. released their largest 4-stroke single-cylinder engine yet, the FS-200S, which packs a full two cubic inches (32.4 cc) of displacement! This is a big step up from the 1.20 Surpass, which used to be the biggest O.S. single 4-stroke engine available. This engine adds an exceptional choice for folks considering a 1.50- to 2.20-size 4-stroke engine for their next modeling project. Featured in RC Sport Flyer (July 2008)
