The General Aircraft G1-80 Skyfarer was a 1940s American two-seat cabin monoplane aircraft built by the General Aircraft Corporation of Lowell, Massachusetts.
The General Aircraft Corporation was established to build an aircraft designed by Doctor Otto C. Koppen from the Massachusetts Institute of Technology. [1] The aircraft was the G1-80 Skyfarer, a two-seat cabin high-wing braced monoplane with a light alloy basic structure and a mixed steel tube and fabric covering. It had an unusual tail unit, a cantilever tailplane with the elevator mounted on the upper surface of the tail with aluminum endplate fins and no movable rudders. It was powered by a 75 hp (56 kW) Avco Lycoming GO-145-C2 geared air-cooled four-cylinder engine. [2]
The aircraft incorporated aerodynamic control principles covered by patents issued to Fred Weick, an early aeronautical engineer who went on to design and market the Ercoupe. Since it had no rudders (or rudder pedals), it was simpler to fly (it had a single control wheel, which controlled the ailerons and elevator), and was considered spin-proof. The aircraft was certified in 1941 with a placard that stated that the aircraft was characteristically incapable of spinning. [3] It was claimed that an average person could learn to fly the Skyfarer in about an hour. [4]
It was anticipated that many aircraft would be ordered and built, but the United States became involved in the Second World War and the Skyfarer program was abandoned after either 17 or 18 examples had been built. [5] At one point, a company called Tennessee Aircraft planned on manufacturing the airplane. [6] However, the rights and tooling passed to Grand Rapids Industries, who built two aircraft before stopping production. [7] The company became a manufacturer of the Waco CG-4A troop glider.
The prototype was built in 1937 in a stable behind the General Aircraft Company president's house. [8]
In October 1944, a Skyfarer was used by Alverna Babbs, the first legless pilot to be granted a student pilot's permit, to complete her first solo flight at Lunken Airport. [9] [10]
L.W. DuVon and Dr. David O. Kime of Western Union College convinced the type holder Grand Rapids Industries, to give the equipment, tools and one of the finished planes to the college. They then found local investors who formed Mars Corporation in 1945. The aircraft was later licensed as the Mars M1-80 Skycoupe with a 100 hp engine. One example was built and production plans were estimated to be as high as 75 planes in its first year. The glut of aircraft produced after the war left little market for the aircraft. The facility to manufacture the aircraft was sold by 1946. [11] [12]
The aircraft, NC29030, resides in the Plymouth County, Iowa Historical Museum. [13] [14]
General characteristics
Performance
The ERCO Ercoupe is an American low-wing monoplane aircraft that was first flown in 1937. It was originally manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war. The final model, the Mooney M-10, first flew in 1968 and the last model year was 1970. It was designed to be the safest fixed-wing aircraft that aerospace engineering could provide at the time, and the type continues to enjoy a faithful following.
The PA-20 Pacer and PA-22 Tri-Pacer, Caribbean, and Colt are an American family of light strut-braced high-wing monoplane aircraft built by Piper Aircraft from 1949 to 1964.
The Taylorcraft B is an American light, single-engine, high-wing general aviation monoplane, with two seats in side-by-side configuration, that was built by the Taylorcraft Aviation Corporation of Alliance, Ohio.
The Piper J-4 Cub Coupe is a two place side-by-side version of the Piper J-3 that was built between 1938 and 1942 by Piper Aircraft. It was Piper's first model with side-by-side seating; combined with docile low-speed handling, this made it a good trainer.
The Oberlerchner JOB 15 was an Austrian two-seat light aircraft produced by Josef Oberlerchner Holzindustrie, which had previously designed and built gliders.
The Call-Air Model A is an American two- to three-seat utility aircraft designed by the Call brothers and built by the Call Aircraft Company, later developed into a successful line of agricultural aircraft.
The MBB 223 Flamingo was a light aircraft developed in West Germany in the 1960s in response to a competition for a standard trainer for the country's aeroclubs. Designed by SIAT, it was a conventional low-wing monoplane with fixed tricycle undercarriage. The cockpit was enclosed by a large bubble canopy. SIAT had not undertaken much production of the type before the firm was acquired by MBB in 1970. Eventually, the new owners transferred production to CASA in Spain.
The DINFIA IA 45 Querandi was a 1950s Argentine twin-engined light transport aircraft built by the DINFIA.
The Funk Model B was a 1930s American two-seat cabin monoplane designed by Howard and Joe Funk. Originally built by the Akron Aircraft Company later renamed Funk Aircraft Company.
The Hindustan Aeronautics HA-31 Basant is a 1970s Indian agricultural monoplane built by Hindustan Aeronautics.
The Piper Aerostar is an American twin-engined propeller-driven executive or light transport aircraft, designed by Ted R. Smith. It was originally built by Ted Smith Aircraft Company, which after 1978 became part of the Piper Aircraft Corporation.
The Max Holste MH.52 was a 1940s French-built two-seat touring or training monoplane designed and constructed by Avions Max Holste.
The Lake Buccaneer is an American four-seat, light amphibious aircraft derived from the Colonial C-2 Skimmer, itself a development of the three-seat Colonial C-1 Skimmer.
The SIAI-Marchetti S.210 was a 1970s Italian twin-engined cabin-monoplane designed and built by SIAI-Marchetti as a development of the single-engined SIAI-Marchetti S.205.
The Neiva Campeiro is a Brazilian two-seat utility monoplane built by Indústria Aeronáutica Neiva for the Brazilian Air Force. The Campeiro was based on the earlier Neiva Paulistinha 56 with a re-designed structure and powered by a 150 hp (112 kW) Avco Lycoming O-320-A piston engine. The Camperiro was a braced high-wing monoplane with a fixed tailwheel landing gear. Twenty aircraft were built for the Brazilian Air Force as the L-7 Campeiro and were used for liaison, observation, rescue and training.
The Stout Skycar was a series of four one-off American light aircraft of the 1930s.
The Eshelman FW-5 was a 1940s American experimental cabin monoplane designed and built at Dundalk, Maryland by the Cheston L. Eshelman Company.
The FLUGWAG Bremen ESS 641 was a 1970s German glider-towing monoplane designed and built by the Flugwissenschaftliche Arbeitsgemeinschaft Bremen research organisation.
The Speedtwin E2E Comet 1, originally named the Phillips ST1 Speedtwin, is a two-seat, twin engined aircraft designed in the UK to be capable of aerobatics and the only civil twin certified for intentional spinning. After a long development time, just two have been built.
Alverna Babbs Williams was the first American pilot with disabilities to earn a pilot's license.
