Fairchild-Caminez 447

The Engine Specifications
In 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 rpm.

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.
