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.
The Junior KN-2 (KN came from the initials of builder Kenny and designer Nicholson) was a high wing monoplane with 5° of sweep and 1.5° of dihedral. The fabric-covered wings used the popular, flat-bottomed Clark Y profile and were built around laminated spars, aluminium alloy (Hyblum) ribs and steel tube drag struts. The ailerons were of the Frise type and had dural structures. The wings could be folded for transport or storage. [1]
The fuselage was a Chromium-Molybdenum steel tube structure of Warren truss form and was fabric-covered. [1] The engine was nose-mounted, with a choice between the Continental A40 flat four and the Szekely SR-3 three cylinder radial engines. Both provided about 40 hp (30 kW). [1] [2] The Junior's two seat cabin was under the wing and provided two side-by-side seats with dual control. Behind the wing the fuselage tapered to the tail with the tailplane mounted on top, wire-braced from a triangular fin which carried a broad and largely straight-edged rudder. [1]
The Junior's landing gear was fixed and conventional, with a long tailskid. It had Goodyear Airwheel mainwheels, with large, low pressure tyres on split axles with semi-oleo landing struts from the upper fuselage longerons and drag struts from the lower longerons. The wheeled undercarriage was designed so it could be easily replaced by floats. [1]
Its benign flight characteristics had been established by June 1931 [1] but with the Great Depression deepening, only one was completed. [2]

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 Pacer Monoplane was a parasol wing, four seat, light aircraft, flown and produced in the US in the late 1920s.
The Moreland M-1 was a 1929 U.S. three seat civil aircraft. Only four were built.
The Wallace Touroplane was a late 1920s U.S. three seat, high wing cabin monoplane. About 20 were built.
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 Franklin Sport is a two seat sport and training biplane built in the U.S. in 1930. Several different engines, in the power range 55–90 hp (41–67 kW), were fitted. Two remained airworthy in 2011.
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 Ogden Osprey was a three engine, high wing monoplane airliner which seated six. Designed in the United States and first flown in the spring of 1930 or earlier, six were built and some used commercially before Ogden Aeronautical ceased trading in the Great Depression.
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.
