“Little Dominator” Model Aircraft Engine

When Noel Jensen of Montana needed an engine for his model airplane he drew a couple sketches, went into his workshop and produced a rotary valve, twin cylinder, air-cooled engine that he called the “Little Dominator.” His engineering and machining skills led him to a simple design and efficient powerplant finished in 1993. The engine’s one-inch bore and 1.1-inch stroke turns a 16/6 propeller at 6000 revolutions per minute. The engine burns methanol on glow ignition and utilizes belt driven rotary (cylindrical) valves for induction and exhaust. The Little Dominator is 8″-long, 8″-wide, and 9″-high.
