The Warner Scarab is an American seven-cylinder radial aircraft engine , that was manufactured by the Warner Aircraft Corporation of Detroit , Michigan in 1928 through to the early 1940s. In military service the engine was designated R-420 .
8-656: Among the many uses for the Scarab, the engine was fitted to the Cessna Airmaster and the Fairchild 24 (UC-61 or Argus). Notably, in 1942, it was put into use powering the Sikorsky R-4 , the first helicopter to be put into production. Many of these reliable engines soldier on today, still powering the aircraft to which they were originally mounted. The Warner 145 and 165 hp engines are the most commonly seen of
16-542: The C-145 and C-165 was the engine horsepower, with the latter having an upgraded 165 hp (123 kW) Warner engine. It was with the beginning of World War II that the Airmaster line came to an end. The welded tubular fuselage, fabric-covered body, extensive woodwork, wooden wings and radial engines, all characteristic of 1930s-era aircraft technology, became too expensive and slow to produce. The old-style aircraft
24-504: The C-34 model was in June 1935. Not long after introduction of the C-34, Clyde Cessna retired from the aircraft industry, leaving the company to his nephew. The original Airmaster, the C-34, evolved into more advanced versions of the Airmaster. The C-37 had a wider cabin, improved landing gear and electric flaps. The C-38 had a taller vertical tail, curved main gear legs and a landing flap under

The Airmaster played an important role in the revitalization of Cessna in the 1930s after the crash of the aviation industry during the Great Depression . In the mid-1930s, nearing
40-524: The end of the Great Depression, the American economy began to slowly strengthen. Dwane Wallace (founder Clyde Cessna 's nephew who was a recent college graduate in aeronautical engineering) decided to assist his uncle and cousin, Eldon Cessna (Clyde's son), in building more modern airplanes for Cessna Aircraft. The design of the first Airmaster is credited to Wallace, and the first flight of
48-587: The fuselage. Changes common to both the C-37 and C-38 included wider fuselages and landing gear along with rubber engine mounts to hold the 145 hp (108 kW) Warner Super Scarab engine. The final revisions of the C-34 were the C-145 and the C-165, of which 80 were built. On these models, the belly flaps added on the C-38 were removed and the overall length of the fuselage was increased. The only difference between
56-481: The small radials for US-built pre-World War II era aircraft, in large part because of good parts availability due to the engines having been used on World War II Fairchild UC-61s and Meyers OTWs. Warner engines are also in demand as realistically sized, though far more powerful, replacement powerplants for many replica or restored World War I era airplanes which were originally fitted with rotary engines .

64-455: Was quickly replaced with aircraft constructed from aluminium with strut braced wings first seen in the Cessna 120 . The design of the C-34 incorporates characteristics that were borrowed from previous models of Cessna Aircraft. These similarities include the high mounted cantilever wing and the narrow design of the cabin windows. The wings and tail surfaces were composed entirely of wood while
