The Neilson NC-1 Golden Bear, aka Neilson Coach was an American, three-place, high wing cabin aircraft, flown in 1929. It did not go into production.
The Golden Bear was a high wing aircraft built around a welded steel tube structure which incorporated chrome-molybdenum alloys where stresses were high. The two spar wing was rectangular in plan and braced to the lower fuselage longerons with parallel struts from the spars. The central wing was joined to the top of the cabin. On the prototype the wing, like the rest of the aircraft, was fabric-covered, though production models would have had metal covering. [1]
The prototype was powered by a 150 hp (110 kW) Comet 7-D seven cylinder radial engine, mounted with its cylinder heads exposed for cooling, though the second example was scheduled to have a seven cylinder 300 hp (220 kW) Wright J-6-7 Whirlwind. The cabin was well-windowed for both pilot and passengers, with a windowed luggage compartment aft and doors on both sides. There were two unusual safety features. The central wing structure provided space for an aircraft rescue parachute, a concept under test at the time. Second, the cabin doors could be jettisoned together in flight with a single lever so that the two passengers could escape individually and rapidly by parachute. The tail was conventional, with a low aspect ratio, roughly rectangular plan horizontal tail mounted on top of the fuselage. It had a cropped triangular fin with a rounded, balanced rudder which reached down to the keel. [1]
The Golden Bear had conventional, fixed landing gear, with independent axles and drag struts from the lower fuselage longerons. The vertical, shock absorbing legs were mounted on the forward wing struts at points reinforced by short struts to both upper and lower fuselage longerons. Its tailwheel was also fitted with a shock absorber. [1]
The date of the Golden Bear's first flight is not known, though its test programme was flown by Ray Crayford from the then new Berkeley, California airport. By August 1929 the first production shop of a proposed factory was completed. [1] The prototype survived until August 1939 when it was destroyed by a crowd at an Oakland Speedway thrill show, disappointed at not getting their money's worth. It is not known if the second example was completed. [2]

General characteristics
Performance
The Pander E was the first indigenous Dutch training aircraft, used by clubs and also privately owned. A two-seat, single-engine biplane, 17 were built in the Netherlands from 1926 with engines of increasing power.
The Romano R.16 was a three engine, high wing monoplane designed for policing and other rôles in France's African colonies.
The Emsco B-2 Challenger was a US three-engined, six passenger aircraft flown in 1929. Only two were built and they were quite soon converted into two different Emsco types, one with one engine and the other with two.
The S.A.B.C.A. S.XII or S.A.B.C.A S.12 was a four-passenger light transport aircraft with three engines and a high wing, built in Belgium in the early 1930s.
The Albert A-10 was a four-seat French transport aircraft which could be rapidly converted into an air ambulance. Two or three examples were built between 1929 and 1932, using at least two different engines, but neither variant reached production.
The Yackey Monoplane was an American three seat parasol monoplane flown in the late 1920s. Two prototypes had some success in the 1927 New York - Spokane National Air Derby and orders were placed but a crash killed its designer and ended production.
The Stiles Dragon Fly was an American two seat monoplane aircraft of the late 1920s. It was aimed at private and club owners. Significant production was planned but few were built.
The Simplex Red Arrow was a US single-engined monoplane produced in the late 1920s and early 1930s and intended as club machine or mail transport. Most used radial engines in the 90–110 hp (67–82 kW) range. They carried one or two passengers whose seats could be open or enclosed. One variant, the Red Arrow Dual Plane, was easily converted from monoplane to biplane and was available with two versions of the much more powerful Wright Whirlwind engines. In all about 20 were built.
The Miami Maid was a US three passenger amphibian first flown in 1929. Despite ambitious production plans, only two were built.
The American Eagle Phaeton was an American three seat, single engine sports biplane produced from 1929 until American Eagle failed financially in 1932. About 34 were built.
The Inland Sport series of parasol wing, sport and training side-by-side two seaters, introduced between 1928 and 1930, differed chiefly in their engines. They used three different radial engines, more than doubling the Sport's power over two years of development. 34 examples were built and frequently re-engined.
The Wallace Touroplane was a late 1920s U.S. three seat, high wing cabin monoplane. About 20 were built.
The Hodkinson HT-1 was a U.S., eight place, three-engined sesquiplane, first flown in 1929. Despite an order for five, only one had been completed before Hodkinson Aircraft went bankrupt near the start of the Great Depression. It operated in Guatemala for several years.
The Watkins Skylark was an American low-wing, cantilever two-seater designed for private and club use. A large anticipated production run in 1930 ended early when the company collapsed in the Great Depression, with only five or six registered.
The Zenith Albatross Z-12 was a large, three-engined airliner built in the United States in 1928. It could carry up to 11 passengers. Only one was completed.
The Ireland Privateer was a 1930s American two-seat, single pusher-engined monoplane sports flying boat which could be equipped as an amphibian. About 18 were built.
The Huntington H-11 Governor was a two-seat cabin monoplane with a high, cantilever wing built in the United States and first flown around 1930. Three were completed.
The Lincoln AP was a U.S., single engine, high wing, general purpose civil cabin aircraft first flown in 1930. Only four were built.
The Zenith Z-6 is a single engine biplane U.S. airliner built in the late 1920s. Its cabin, in the fuselage immediately behind its radial engine, holds five or six passengers depending on engine power. It is flown from an open cockpit further aft. Nine were completed and one has been restored to flight.
The Nicholson Junior KN-2 was a low power, high wing, two seat, cabin monoplane intended for sport or flight training in the United States in the late 1920s. Only one was built.
