The Fieseler Fi 5 was a single-engined two-seat sportplane of the 1930s. It was produced by the German aircraft manufacturer Fieseler Flugzeugbau, which was started by the World War I fighter ace and German aerobatic star, Gerhard Fieseler.
The Aero A.14 was a Czechoslovakian biplane military reconnaissance aircraft built in the 1920s. It was essentially a slightly modified version of the Hansa-Brandenburg C.I aircraft, widely-used by Austria-Hungary during the First World War, and for this reason, the aircraft is sometimes referred to as the A.14 Brandenburg. When equipped with a slightly different engine, the aircraft was designated A.15 instead. The two versions were otherwise almost identical.
The Aero A.101 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s.
The Aero A.300 was a Czechoslovak bomber aircraft that first flew in 1938 as a much refined development of the A.304. It was designed by Aero to meet a requirement for a bomber-reconnaissance aircraft for the Czechoslovak Air Force, the Aero A-304 transport/bomber formed the basis for its design. It was a four-seat aircraft powered by two Bristol Mercury IX radial engines. The A-300 was faster than any other Czechoslovak aircraft in the inventory except for the Avia B-35 fighter. Despite showing much promise, development and production of the aircraft was stopped by the German occupation of Czechoslovakia.
The Aero Ae 50 was a prototype propeller-driven military reconnaissance aircraft built in Czechoslovakia.
The Aero L-60 Brigadýr was a small, high-wing propeller-driven Czechoslovakian STOL utility aircraft developed for both civil and military use. A prototype, designated XL-60, with Argus As 10C engine, first flew on December 24, 1953, but it was not successful. The plane was thoroughly redesigned and the second improved prototype, with M-208B flat-six engine, flew on June 8, 1954. The aircraft's configuration bears a strong resemblance to the Fieseler Fi 156 "Storch" licence-produced in Czechoslovakia during and after World War II, and which this aircraft was intended to replace. By the end of production in 1960, 273 had been built by Aero, including an improved version, the L-160 with an all-metal tail.
The RWD 9 was a Polish sports plane of 1934, constructed by the RWD team.

The Mráz M-3 Bonzo was a light aircraft built in Czechoslovakia in 1948 as a further development in the family of light aircraft that had commenced with the M-1 Sokol.
The Letov Š-32 was an airliner produced in small numbers in Czechoslovakia during the 1930s. It was a trimotor monoplane with a high, cantilever wing, and was designed to meet a requirement by ČSA for a machine to service a night route between Prague, Bratislava, Uzhorod, and Bucharest. It could carry up to six passengers in a fully enclosed cabin which was praised at the time as being "particularly roomy and lofty". The wings were of all-metal construction, and the fuselage was built up from steel tube and was mostly skinned in metal, other than its very rear part, which, like the empennage, was fabric-covered.
The Pazmany PL-9 Stork is an American single-engined high-wing monoplane designed by Ladislao Pazmany as a ¾ scale variant of the Second World War Fieseler Storch for the home builder market.
The Bernard H.52 was a French floatplane fighter aircraft of the 1930s. It was a single engine, single-seat monoplane built in the hope of being selected by the French Navy. Two prototypes were built, but no production followed.
The Cunningham-Hall GA-21 was an American two-seat monoplane design to compete for the Guggenheim Safe Aircraft Competition in 1934. Its distinguishing feature was full span flaps which could be manually or automatically adjusted. The GA-36 was a military version of it with tandem, rather than side-by-side seating.
The Fieseler F 4 was developed, built and flown as a two-seat sports and travel aircraft at the Fieseler Flugzeugbau.
The Caproni Ca.120 was a three-engine monoplane bomber built by Caproni in the 1930s.
The Praga E-51 is a Czechoslovakian reconnaissance aircraft and light bomber built by Praga in the 1930s. Development was halted by the annexation of Czechoslovakia by Germany, after only one prototype had been built. The appearance of the construction is very reminiscent of the contemporary twin engined fighter, the Fokker G.I from Holland.
