OS FS 95V Ringed 4-Stroke Glow Engine is a ringed, .95-displacement four-stroke powerplant designed for RC airplanes. It delivers steady, balanced power with the classic four-stroke character. Its nostalgic styling features individual valve covers and machined aluminum pushrod guides, and the carburetor is mounted on the centerline for easy installation in a range of models. The package includes a Jet Stream muffler for an authentic four-stroke sound, plus a glow plug and header. With more displacement than smaller engines yet light for its class, the FS 95V provides dependable torque across the power band. It suits a broad range of airframes, including models designed for 0.60 cu in two-stroke and 0.90 cu in four-stroke classes, making it a versatile choice for scale and sport models seeking the look and feel of a traditional four-stroke powerplant.
