Best O.S. Engines products in the RC motors category
On this page you'll find a ranking of the best O.S. Engines products in this category. To give you a quick overview, we've already ranked the most important information about the products for you.
1. O.S. Engines Os A5
Which glow plugs for which engines and applications?
A cold plug should be installed in engines with high displacement, during full throttle operation, when using fuels with a high nitromethane content, in high ambient temperatures, or with poor cooling.
Medium "standard" plugs are recommended for low fuel nitration, in engines with low compression and power, etc. The medium glow plug type is usually the most cost-effective all-round plug and should be the first choice when tuning for the specific engine type.
Hot glow plugs are advisable if the engine has poor idle characteristics, when little nitromethane is used, in engines with low displacement, in very low ambient temperatures, or when the engine is predominantly operated in partial load conditions.
2. O.S. Engines O.S. FS-64V w/F-4050 Silencer
The O.S. FS-64V engine with F-4050 silencer is a highly developed combustion engine specifically designed for use in RC airplanes. With a nostalgic design reminiscent of engines from the 1930s, this motor combines classic aesthetics with modern technology. The FS-64V offers impressive performance and allows the use of propellers in various sizes without any loss of power. The newly designed cylinder head and increased combustion chamber volume provide an authentic 4-stroke exhaust sound and improved performance. The F-4050 silencer is designed to optimize exhaust performance while maintaining the characteristic sound of a 4-stroke engine. This motor is ideal for model builders who value performance and a realistic flying experience.

6. O.S. Engines Candles Os 3a
Designation before A3
Which glow plugs for which engines and applications?
A cold plug should be installed in engines with high displacement, during full throttle runs, when using fuels with a high nitromethane content, at high ambient temperatures, or when cooling is poor.
Medium "standard" plugs are recommended for low fuel nitration, in engines with low compression and power, etc. The medium glow plug type is usually the most affordable all-round plug and should be the first choice when tuning for the specific engine type.
Hot glow plugs are advisable when the engine has poor idle characteristics, when little nitromethane is used, in engines with low displacement, at very low ambient temperatures, or when the engine is predominantly operated in partial load conditions.

9. O.S. Engines Glow Gasoline Engine Plug G5 (71655001)
Glow plugs serve the same function in model engines as spark plugs do in automotive engines. Like their larger counterparts, they differ in heat values. Glow plugs are categorized into cold, warm, and hot plugs, which vary in the length and thickness of the heating coil as well as the size of the coil space. Additionally, the choice of metal alloys (platinum-iridium-nickel) significantly affects the heat value and durability of the plug. Plug type: G5, application area: gasoline engines.
