When talking about model airplane engines for radio control use, by far the most common type is the glow plug engine, often also called a nitro or even gas engine.
The term gas has widely been used to describe all types of Internal Combustion (IC) powered rc engine, whereas many people - especially in North America - know gas just to mean gasoline, or petrol.
Nitro is a name that's really been adopted from the radio control car world, but is commonly used to describe all glow plug powered RC models. The word nitro comes from nitromethane, an ingredient of glow fuel.
