Small, light AND SIMPLE. No liquid cooling, no knock sensor, no computer controlled fuel injection, no O2 monitoring or exhaust gas recirculation, no transmission. Often the pilot controls the air/fuel mixture manually watching rpm and exhaust temp. Very primitive, but not a lot can go wrong as long as you don't have detonation which tear up an engine pretty quickly.
