The Berger 2-cycle radial aircraft engine was designed and built by Lee Berger, of CA, circa 2001. This is one of the larger radials built by Mr. Berger, and though it appears to be a four-stroke, it is actually a two-stroke engine. It is model 7455-11 and measures 11″ in diameter, 10″-long, sports K&B .61 cylinders and heads, and is designed to burn methanol on glow ignition. Lee added nonfunctional pushrods and rocker boxes so the engine would appear scale in a model airplane. The engine is equipped with a 4 vane cylindrical supercharger in back to pressurize the crankcase for operation.
