FG-21 Four-Stroke Petrol Engine

- The FG-21 runs with any good quality forecourt petrol, mixed 20:1 with oil.

- Power comparable to that of the FA-125a.

- High quality professional finish adds scale realism.

Spurred on by the success of the FG-36, Saito have developed a smaller petrol four stroke engine, the FG-21. Supplied with an electronic ignition system, the FG-21 offers power comparable with Saito's FA-125a glow engine. The carburettor features a diaphragm pump that is very tolerant of differences in fuel levels, making it unfussy regarding fuel tank positioning. This means you can now fit the tank to give the best centre of gravity for the airframe rather than worrying about the best position to keep the engine running. The pump also allows for smooth running during advanced aerobatic manoeuvres.
