If you want your model jet to travel at a high rate of speed, you will need an internal combustion engine.
This type of engine is one of the fastest engines for any RC craft, and some even have the ability to propel model jets over two hundred miles-per-hour.
A downside to combustion engines is that they are very noisy and difficult to maintain.
Some areas have even banned the use of this type of plane because of the noise and danger factor.
For heavy and large RC aircraft, the most popular engine type is the glow engine.
A glow engine uses a special fuel source that can be difficult to obtain or make.
This mixture consists of a lubricant (synthetic oil or castor oil), nitro-methane, and methanol.
If you are creating the mixture yourself, it is very important to get the mixture right or your airplane may quickly break down.
Just like with a car, a RC combustion engine requires a starting mechanism, or spark plug, to start the ignition.
This glow plug is heated electrically until it reaches a high enough temperature to create ignition.
Once there is ignition, the engine is fairly self-sustaining.
The starting process only takes a few seconds, thanks to a powerful battery unit.
The simplest combustion model jet planes use a two-stroke cycle.
This kind of engine is fairly cheap compared to the other models, but it offers the best ratio of power to weight for all combustion engines.
An engine that uses a six stroke or four stroke cycle will have better fuel efficiency, but it will deliver less power for the weight of the plane.
Even though the larger engines have better fuel efficiency, they will still burn more fuel than the small engines.
A better fuel efficiency just means that they burn less fuel compared to the power of the engine.
Internal combustion model jets are available in a variety of engine configurations.
Some models can use diesel as a fuel source, while others may work like a semi-hybrid.
A diesel engine does not require a spark plug because it receives ignition from compression.
The compression ratio on this engine can be controlled via a T screw on the head of the cylinder.
Diesel powered jets are optimal for long flights since the fuel can last longer.
Diesel planes may have a mixture of kerosene and ether in the fuel to give it a higher energy content.
