the mid-1920s, Harold Caminez designed a radial engine that was
lighter and used about half the parts needed for a conventional
radial while producing the same power. Instead of a crank
shaft, his engine used a large camshaft. There was no need for
connecting rods, crankshaft throws or counterweights, or valve
timing gears. The engine produced its rating at only 1,000
The Caminez 447 first flew in 1926.
Because of its light weight and low rpm, it vibrated excessively and
plans to market the engine were abandoned in 1929.
