The AM10 engine is a 1.0 liter 3 cylider automotive engine of 75 hp converted to aircraft use. This engine is comparable in power and/or weight to the Rotax 582. Built in upright version. They are mostly used in trikes, light twins and replica aircraft that require a narrow engine package. All of our engines are assemble by us from all new parts. We never use any unknown JDM, used, "rebuilt", "on condition" or other junk yard parts by any name. Why buy a used engine when you can buy all new for less.
