The Rearwin Cloudster was a two or three-seat civil utility aircraft produced by the Rearwin Aircraft & Engines Company of Kansas City, Missouri beginning in 1939. [1] It was a strut-braced, high-wing monoplane of conventional design with an enclosed cabin and fixed, taildragger undercarriage. [2] One specialized version was produced as a trainer for Pan American Airways. [1]
Rearwin Aircraft began developing the Cloudster in 1938, while still selling the older Speedster and Sportster. The goal was to develop an aircraft with side-by-side seating, using as much tooling and existing equipment as possible. [3] : 162–163 Widening either the Speedster or Sportster was considered, [4] but by the time the design was completed, the strut geometry, landing gear, fuselage structure, engine installation, and cabin had to be changed. [3] : 162–163 Development of the prototype took 6 months. [3] : 164
Originally the plane was dubbed the "Rearwin Coupe," a name which changed to "Cloudster" after a month. The 90hp prototype (Model 8090) was never developed for production, instead the basic Model 8125 used a 120hp Ken-Royce 7F engine also made by Rearwin. In 1940, the Model 8135 added a third, sideways-facing, seat to the Model 8125. [3] : 164–165
Pan American Airways founder Juan Trippe, who personally owned a Rearwin Sportster, approached the company in 1941 to develop an instrument trainer. The existing Model 8135 was redesigned and certified in four months as the 8135T. Pan Am bought 5 of the design, while another 20 went to various operators. [3] : 173–175
The Cloudster was a two- or three-seat aircraft of high-wing design and conventional landing gear arrangement. [1] [2] Designed to seat two side-by-side, the Model 8135 introduced a third seat behind the front row which could be accessed by folding the right-hand seat forward. The last model, Model 8135T, sat two in tandem. [3]
All versions used Ken-Royce radial engines of 90-120hp, as the engines were produced by a division of the Rearwin Aircraft & Engines Company and the company was experienced building airplanes with small radial engines. Beginning in late 1941, the Cloudster used a NACA cowling hinged along the top for engine access. [3]
The interior of the Cloudster (or at least the prototype) used surplus cloth from Cadillac and a simulated woodgrain panel. A baggage compartment held 50lbs. [3]
The tandem seating Model 8135T introduced jettisonable doors for both the instructor and student pilot, dual controls, and seats with removable cushions to accommodate backpack or seat parachutes. The student sat in the rear seat with their own controls and a removable instrument panel. The 8135T included fittings for a blackout curtain surrounding the student for instrument training, while allowing the instructor to maintain normal visibility. [3] : 173–175
In 1941, 25 Model 8125 Cloudsters were exported to the Aero Club of Iran. The aircraft remained in service as of 1945, with a .30 caliber machine gun mounted on the left wing strut outside the propeller arc. [3] : 169–170
From August 1941 to July 1942, 25 Model 8135T trainers were sold to various operators. How long they served is unknown. [3]

Rearwin Airplanes was a series of US airplane-manufacturing businesses founded by Andrew ("Rae") Rearwin in 1928. Rae Rearwin was an American businessman who had developed several successful business ventures in the Salina, Kansas area in the early 20th century. Although he had no experience with aircraft manufacturing, he felt that he could succeed with his solid business acumen. With his two sons, Ken and Royce, he hired some engineers and built the Ken-Royce in a garage in Salina. The business moved to the Fairfax Airport in Kansas City, Kansas, and went through several variations before it was sold to Commonwealth Aircraft in 1942, which went bankrupt in 1946.
The Aeronca L was a 1930s American cabin monoplane designed and built, in small numbers, by Aeronca Aircraft. It differed significantly from other Aeronca planes by the use of radial engines, streamlining, and a cantilever low wing.
The LeBlond radial engines, later produced under the name Ken-Royce, were a family of 3-cylinder, 5-cylinder and 7-cylinder, air-cooled radial engines for aircraft, built in the 1930s by the LeBlond Aircraft Engine Corporation until the operation was sold to Rearwin Airplanes in 1937 and renamed Ken-Royce Engines.
The Kinner Sportster was a 1930s American light monoplane built by Kinner Airplane & Motor Corporation.
The Commonwealth Skyranger, first produced as the Rearwin Skyranger, was the last design of Rearwin Aircraft before the company was purchased by a new owner and renamed Commonwealth Aircraft. It was a side-by-side, two-seat, high-wing taildragger.
The Meyers OTW was a 1930s United States training biplane designed by Allen Meyers and built by his Meyers Aircraft Company from 1936 to 1944.
The Gee Bee Model Y Senior Sportster was a sport aircraft built in the United States in the early 1930s by the Granville Brothers. Essentially an enlarged two-seat version of the single-seat Sportster, it was a low-wing strut-and-wire-braced monoplane of conventional design with open cockpits and fixed tailskid undercarriage. The first of the two examples constructed remained with the Granville Brothers company and competed in many races, piloted by Maude Tait and Russell Boardman, among others. Later it also served as a support aircraft for the R-1 and R-2 racers. The second Model Y was built to order for the Cord Auto Company to be used as an engine testbed for the Lycoming R-680 engine they produced. This aircraft was later refitted with a Wright Whirlwind of nearly double the power of its original powerplant. In this form, it was flown by Florence Klingensmith at the 1933 Chicago International Races, where she won second place in the Women's Free-For-All, then perished in the aircraft after fabric became detached from the upper right wing while contesting the Phillips Trophy.
