This article is aimed at the modeler who is comfortable starting, running, and flying with glowplug-ignited engines - the standard type used in the United States. My intent is to familiarize you with the uses, running and care of model diesel engines. Although the vast majority of modelers in the United States fly "glow" engines, there are some interesting alternatives. The most-advertised alternative engine technology is the four-stroke engine, followed by the diesel, and finally now, the turbine. The technology you choose depends on what you are planning to do. Turbines speak for themselves. If you are into jets and have the money, expertise, and desire, is there an alternative? Four-stroke engines are well documented, are available everywhere, and are very "in." They are quiet, economical of fuel, and swing very large props.
