There are many excellent engines that will work well in Troy Built Models aircraft. Following are engines that we personally have had first hand experience. All of these engines are excellent and are recommended. They start easily, run well, have excellent power to weight, look good, and can be easily repaired by the manufacturer if necessary. Mufflers and propellers are readily obtainable and varied to suit many needs. If you fly a lot, consider a gasoline engine, as the operating costs are lower though the initial cost is higher. The initial cost premium can be made up in as little as a month or two of heavy flying.

If you are familiar with any of the engines listed below and prefer to use an engine that is similar, we would expect similar performance. We would like to hear any feedback on a setup that you have tried successfully.

We are currently investigating 3 blade props and muffler systems that will reduce the noise levels substantially. It is important to put baffles into the cowls to direct the airflow through the cooling fins. This is easily done. We will provide photos of the baffles where possible. For IMAC* type flying these planes must be grossly overpowered, which means that the engine weight is a very large part of the overall weight of the plane. For this reason, the engines are generally mounted as far back as possible, and the radio gear is mounted in the tail section for balance reasons. Troy Built Models aircraft are built around these specifications.

*IMAC is for flying competition with scaled down versions of full-scale aerobatic planes like the Staudacher, One Design, Extras, Edge, Caps, and others. There are several levels of competition. Generally the more difficult the level, the more power to overall weight is necessary to complete the maneuvers. The most difficult level is called "Unlimited".
