In the early 1990s, Mike Goldowsky designed this 6-cylinder 2-cycle engine in an attempt to make a powerful radial engine that would be economically attractive to the average modeler. His goal was to retail it for less than $1000, so he purchased 6 K&B (Lake Havasu, Arizona) single-cylinder airplane engines and mounted them into a machined housing to produce the radial appearance. Each engine has a gear that engages the drive-gear for the propeller shaft. Goldowsky developed a unique linkage that synchronizes the carburetors to operate from one location. The engine is 7”-long, 8”-wide, 9”-high, and weighs 6 lbs. 6 oz.
