RC Engines
From 2-Stroke To Tubine
What are glow rc engines?
R/C models are powered in a variety of ways. Sailplanes, for example, need no power source other than nature. But they’re the exception. Nearly all R/C vehicles, aircraft, boats and helicopters require something to propel them into action.
Electric models use small motors, powered by battery cells. Those motors should not be confused with glow engines — which are actual internal combustion power plants that form the heart of any “gas” or “nitro” powered R/C model.
Most nitro R/C models use a 2- or 4-stroke glow rc engines, sized specifically for that model. Typically, they range in displacement from .049 cu. in. to 1.2 cu. in. (80cc to 20cc) — a variety that satisfies virtually any model’s power requirements.
Glow engines cannot be operated with the same gasoline you’d get at a filling station pump. They require a special fuel, called “glow fuel.” It contains methanol as the base, with varying amounts of nitromethane to increase the energy that the fuel can provide. Oil, pre-mixed into the fuel, lubricates and protects your tiny engine as it pounds out amazing power.
When you get your new engine, first examine it carefully for any obvious defects. Read the operating instructions closely. If the manufacturer suggests a specific procedure for breaking in the engine, by all means, use it!
Two-Stroke vs. Four-Stroke You’ll quickly notice that many R/C models give you the option of installing a 2-stroke OR a 4-stroke glow engine. How do you know which is best?
Two-Stroke simply means that the engine “fires” (ignites the fuel in its combustion chamber) with every revolution of the piston. Generally, they’re a good place for new nitro modelers to start. Two-strokes are easier to operate, less vulnerable to problems if misused, and deliver more power for their size and weight.
Four-Stroke engines fire once with every two revolutions. They consume less fuel, sound more realistic, and provide more torque — but cost more, are harder to adjust and require more maintenance.
