Nitro Engine Brands

Model airplane or glow plug airplane engines

The most common type of model airplane engine is the glow pug engine.  These engines are also called nitro engines because a key ingredient of the fuel is nitro methane. 

Two types of Model airplane engines
2 and  4 stroke engines

Model airplane engines come in  two different types of engines.  You can either get the 2 stroke version or the 4 stroke version for model airplane engines.  The main difference between 2 stroke and 4 stroke model airplane engines is firing cycle.  The 2 stroke fires every revolution and the 4 stroke engine fires once per two revolutions.   Also the two stroke and 4 stroke engines look very different.

Advantages of each type of Model Airplane Engine

The main difference in 2 stroke model airplane engines is that they produce more power for their tiny size and in some cases are easier to use. Typically they are less expensive and easy to run.  The beginning model airplane or RC training planes will feature a 2 stroke engine. 

On the other hand the 4 stroke model airplane engine will generally produce more torque at lower RPMs and is much quieter at low RPM and produces an engine sound that is closer to that real sound.  These engines are used more often by experienced model airplane flyers.

Different Model airplane engine sizes

Model airplane engines displacement is generally expressed in cubic inches.   The model airplane engine manufacturers refer to the size  in terms of 1/100th of one cubic inch, however it is usually just expressed as a number like .40cu.in. So for example a .40 cubic inch airplane engine would be referred to as a 40, and a .60cu.in. airplane engine would be called a 60 an so on. 

Glow plugs for Model Airplane Engines

A normal gasoline car engine uses a typical spark plug to ignite the fuel/air mixture within the engine compression chamber, in the case of a model airplane engine a  glow plug or nitro model airplane engine uses a small glow plug.

At the start the model airplane engines glow plug will need to be heated up using a glow plug igniter, however once the model airplane engine is running the heat generated within the model airplane engine's combustion chamber keeps the plug glowing and is able to ignite the fuel/air mixture on each revolution of the engine.

Unfortunately glow plugs can fail at anytime, so it's always a good idea to have a selection of spare glow plugs available whenever you fly. Looking back when I was a kid I never had spare glow plugs and as a result I did not have much luck getting my model airplane engine or Testors car started.  They were fun to look at but not much else.   Tip have good glow plugs and just like most engines fresh gas is a must.

Model Airplane Carburetors

Most model airplane engines have a very simplistic engine carburetors. the model airplanes carburetor is located on the front of the model airplanes engine body and has a venturi where the fuel and air is mix, and adjustable idle screw that controls the idle speed of the model airplane engine, a gas/air mixture screw, or 'needle valve', to allow you to adjust the fuel/air mixture and a rotating barrel.

The throttle barrel is electronically linked to the airplanes throttle control servo, and rotates in response to the flyers input at the radio transmitter.

Other model airplane engines

Of course the glow plug model airplane engines are by far the most common type found on the flying field, there are other types.  The gasoline, fuelie or petrol engines can be found in larger remote control or rc model airplanes, and these differ to glow engines greatly in terms of physical appearance, design, size and power output.

Gasoline model airplane engines are more expensive and even a smaller displacement gasoline model airplane can run up to a  few hundred dollars, and the larger ones can run into into the hundreds or even thousands of dollars.
