FA-120R3 20cc 4-takts 3-cyl Stjärnmotor Metanol

Saito FA-120R3 Radial Nitro/Glow Engine

• Optimum for small-size scaled airplane
• Low vibration (assured by constant-interval explosion)
• Real sound of the exhaust
• The engine is designed to equalize fuel mixture and minimize misfire due to insufficient distributing at idling by means of special port type intake manifold originally developed by SAITO
• Cylinder head: Improved semi-spherical combustion chamber assures better combustion efficiency and volumetric efficiency
• Cylinder: The aluminum cylinder is directly hard-chrome plated on its inner surface without installing liners to reduce weight and increase durability. The monolithic structure of cylinder head and cylinder prevents distortion and improves cooling efficiency.
• Piston: The piston is made of high silicon content aluminum and attached with a compression ring to heighten engine performance
• Crankshaft: Has a forged solid construction made of chrome molybdenum steel, and supported by two ball bearings
• Camshaft: Features high cam providing longer maximum lift time
• Carburetor: High-performance of slow throttling type
• Propeller nut: designed to have double nuts preventing loosening and fall-off for the safety.
