The SAITO FG engines are gasoline four-stroke engines carefully manufactured especially for model airplanes, which combine high performance and stability with low weight.

The engine is based on the glow igniter engines with some detail changes, with a gasoline-compatible carburetor, as well as an electronic ignition system.

This enables high fuel yield at lower fuel costs, plus less model contamination.

Special features:

Cylinder and cylinder head are one component, this design saves weight, prevents warping and improves cooling.

The cylinder running surface is hard chrome-plated and designed without a liner

Highly silicated aluminum piston with piston ring

Robust connecting rod forged from high-strength aluminium

High-strength crankshaft made of forged chrome-molybdenum steel, 2-fold ball bearings

Camshaft, space-saving gearbox at the front and steep cam flanks for optimum filling

High cylinder efficiency due to hipped roof-shaped combustion chamber

The exhaust noise corresponds to that of a typical four-stroke engine.

The carburetor was specially designed for four-stroke gasoline engines

Electronic battery ignition system for spark plug operation especially for this engine

Operation with normal two-stroke fuel mixture (e.g. moped or lawnmower)

Since the motor can kick back when starting by hand, an electric starter is strongly recommended to start the engine to prevent damage to the engine.
