A model engine is a small, usually gasoline-powered engine that is used in model airplanes, boats, cars, and other vehicles. Model engines are typically much smaller than full-size engines, and they are designed to be lightweight and easy to operate.

Model engines have been around for over a century, and they have become increasingly popular in recent years. This is due in part to the fact that model engines have become more affordable and easier to use. Additionally, there are many different types of model engines available, so there is a model engine for everyone.

Types of Model Engines

There are two main types of model engines: two-stroke and four-stroke. Two-stroke engines are simpler and less expensive than four-stroke engines, but they are also less fuel-efficient and produce more pollution. Four-stroke engines are more complex and expensive than two-stroke engines, but they are also more fuel-efficient and produce less pollution.

In addition to two-stroke and four-stroke engines, there are also a number of other types of model engines, including:

  • Electric engines: Electric engines are becoming increasingly popular in model airplanes and boats. They are quiet, lightweight, and easy to operate. However, they are also less powerful than gasoline engines.
  • Compressed air engines: Compressed air engines are powered by compressed air, and they are a good option for model airplanes and boats that need to be quiet. However, they are also less powerful than gasoline engines.
  • Steam engines: Steam engines are powered by steam, and they are a good option for model trains and boats. However, they are also more complex and expensive than gasoline engines.

Choosing a Model Engine

When choosing a model engine, there are a number of factors to consider, such as:

  • The type of model you will be using Different types of models require different types of engines. For example, model airplanes require powerful engines, while model boats require quiet engines.
  • The power requirements: The power requirements of your model will depend on its size and weight. For example, a large model airplane will require a more powerful engine than a small model airplane.
  • Your budget: Model engines can range in price from a few dollars to hundreds of dollars. It is important to set a budget before you start shopping for a model engine.

Where to Buy a Model Engine

There are a number of places where you can buy model engines, including:

  • Model Engine Online retailers: Online retailers offer a wide variety of model engines at competitive prices.
  • Local hobby shops: Local hobby shops often have a limited selection of model engines, but they can be a good source of information and advice.
  • Manufacturers: Manufacturers of model engines often sell their products directly to consumers. This can be a good option if you are looking for a specific model engine.


Model engines are a great way to learn about engines and how they work. They are also a lot of fun to use. If you are interested in getting into model engines, there are many resources available to help you get started.
