OS Engine

The O.S. FSa-72 II is the latest version of the popular, high-performance four-stroke engine. Updates include a revised oil venting system that now vents from the crankcase instead of the intake, improving the engine's running behavior. The rocker cover is now black to enhance the engine's appearance when used in a scale model.

The FSa-72 II has the same mounting dimensions as the previous generation as well as the older FL-70 and FS-70U. This makes it easy to swap out the engine. The compact external dimensions and the power and torque are ideal for most models designed for 46cc two-stroke or 70cc four-stroke engines.

Like all FS series engines, the FSa II engines feature a super-smooth carburetor with anti-spit intake and an ultra-lightweight silencer. If you've had noise issues while flying, this is the engine you need for your sport model.

The 61N carburetor provides both linear and fuel-efficient engine performance, offering you reliability and precision at all RPMs.

Revised oil venting, black head for use in scale models, ultra-quiet silencer included, 61N carburetor, 1.2 HP power, displacement: 11.79 cc, stroke: 20.6 mm, bore: 20.7 mm, power: 1.2 HP / 12,000 RPM, RPM range: 2400...12,500 RPM, weight without silencer: 530 g, glow plug: OS F-Type (included), recommended propellers: 12 x 7, 12 x 8, or 14 x 6, 14 x 7.
