What Type Of Oil Powered Engine Is Suitable For Aircraft Models?

There are generally two types of aircraft model engines, one is a methanol engine (also known as an electric methanol engine), and the other is a gasoline engine. Small aircraft models (with a wingspan of less than 1.6 meters) generally use methanol engines, because the engine requirements for small aircraft models are small and light, methanol engines are easier to miniaturize, and gasoline engines that are too small are unstable and difficult to adjust, so gasoline engines are not needed.
Aircraft models with a wingspan of more than 1.6 meters generally use gasoline engines. The first reason is that the aircraft is relatively large and can carry larger gasoline engines. The second reason is that gasoline engines are very fuel-efficient, making the aircraft's range longer.
