The Saito FG petrol engine is a four-stroke power plant developed expressly for use in model aircraft, combining high performance and durability with low weight. The engine is based on the FA-220 glowplug engine, but features a number of detail modifications, including a carburettor suitable for petrol and an electronic ignition system.


The result is a very frugal engine with lower fuel costs. Model soiling is greatly reduced, and the engine can be hand-started in the normal direction of rotation - no starting equipment required.


Special features:

oOne-piece cylinder / cylinder head: this method of construction saves weight, prevents distortion and promotes efficient cooling. The inside of the cylinder is hard-chromed; there is no separate cylinder liner.

oRinged, high silicon-content aluminium piston..

oRobust connecting rod forged from heavy-duty aluminium, with phosphor-bronze big-end bush for running on petrol.

oHigh-strength crankshaft forged from chrome-molybdenum steel, supported in twin ballraces.

oSpace-saving front-mounted camshaft and cam gears, with steep-rise cam for efficient fuel induction.

oHighly efficient cylinder with pent-roof combustion chamber.

oSimilar exhaust note to that of a typical single-cylinder four-stroke engine.

oCarburettor with membrane pump, specifically designed for four-stroke petrol engines.

oElectronic battery ignition system expressly developed for sparkplug operation..

oRuns on standard two-stroke fuel mixture (e.g. moped or lawnmower mix)
