Saito FG-36 4-Stroke Gas Elec Ingnition

FG-36 Four-Stroke Electronic Ignition Gasoline Engine

SAITO FG-36 is a four cycle gasoline engine exclusively for model airplanes which is designed with emphasis on high performance, durability, and weight saving and whose parts are modified to adapt to the gasoline engine based on FA-220 glow engine, equipped with four cycle gasoline engine carburetor and ignition system matched to our engine.

Features of the gasoline engine

• Fuel efficient.
• Fuel cost is low.
• The airframe is not easily soiled.
• Manual start is possible for normal rotation.
• No start-up tool is needed.

Features of FG-36

• Cylinder.:  The cylinder head is integrated with the cylinder in order to prevent distortion, save weight and improve cooling effectiveness, etc. Hard chromium is plated in the cylinder without using liners for higher durability.
• Piston.:  High-silicon-containing aluminum piston equipped with compression ring for higher performance.
• Connecting rod.:  Robust with forged high-strength aluminum, As a measure for gasoline engine, phosphor bronze bushing is pressed into the pick end to improve heat resistance.
• Crankshaft.:  Robust with forged chromium molybdenum steel and supported by two ball bearings
• Cam gear.:  Placed in the front for compactification.
• Cam.: High output type, high cam specification
• Combustion chamber.:  Volumetric efficiency and combustion efficiency are improved by adoption of a vent roof type combustion chamber.
• Propeller nut.:  Double nut of drop-off preventing safety design
• Exhaust sound.:  Sound quality similar to the exhaust sound of the real machine
• Carburetor.: Carburetor exclusively for four cycle gasoline engine.(Due to diaphragm pump type, the fuel tank can be located anywhere.)
• Ignition system.: Exclusively for our four cycle gasoline engines using the battery type electronic ignition and the electronic spark advance system.
• Start method.: Normal rotation can be manually started due to automatic spark advance (Please use the starter for safety.).
• Fuel.: With the same composite fuel as two cycle, handling is easy.
• Flight pattern.: Since there are no worries about the inclination of oil, all acrobatic flights are possible.
