Searchlights and other night-flying equipment were added, but the Czechoslovak Air Force were not interested in the project and no sale resulted.

T-28 The T-28 was a Soviet multi-turreted medium tank. The prototype was completed in 1931, and production began in late 1932. It was an infantry support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35 (also multi-turreted), with which it shared turret designs. The type did not have great success in combat, but it played an important role as a development project for Soviet tank designers. A series of new ideas and solutions that were tried out on the T-28 were later incorporated in future models.

Avia BH-9 The Avia BH-9 was a single-seat sports plane built in Czechoslovakia in 1923, based on the BH-5. As with other developments in the BH-1 lineage, the BH-9 was a low-wing braced monoplane that accommodated the pilot and passenger in tandem, open cockpits. The BH-9's structure was strengthened to allow the use of a higher-power engine than in its predecessors, and for the first time, this was a domestically-produced powerplant.

Antonov An-14 The Antonov An-14 Pchelka (Russian: «Пчелка» , "Little Bee", (NATO reporting name Clod) is a Soviet utility aircraft which was first flown on 15 March 1958. It was a twin-engined light STOL utility transport, with two 300 hp Ivchenko AI-14RF radial piston engines. Serial production started in 1966, and about 300 examples were built by the time production ended in 1972. The An-14 failed to replace the more successful An-2 biplane, which was manufactured until 1990, (the An-2 is still manufactured on special order). The An-14's successor, the An-28 with turboprop engines, is still manufactured at PZL Mielec factories in Poland, under the names PZL M28 Skytruck and PZL M28B Bryza.

Aero L-60 Brigadýr The Aero L-60 Brigadýr (Czech: "Brigadier" ) 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 (as K-65 Čáp), 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.

Kh (tramcar) Kh (Russian: Х ) was the class of double axled high-floor tramcars, which were built in Soviet Union in interbellum period. First vehicles were built in 1927 and delivered to Kharkov, Ukraine. First letter of city name, Cyrillic "Х" (usually transliterated as "Kh"), was selected as a designation of whole series. After Kharkiv, tramcars of this type were supplied to many Soviet cities and became most numerous in the fleets of many municipalities. In 1941, after the onset of Operation Barbarossa, their production was stopped for maximizing war efforts. The Kh-class tramcars were finally withdrawn from the city service in the mid-1960s as morally obsolete vehicles, their sturdy construction allowed them to be used much more. The small number of survived cars are preserved for museum purposes in Moscow, Nizhniy Novgorod, Saratov and few other cities.

Avia BH-4 The Avia BH-4 was a prototype fighter aircraft built in Czechoslovakia in 1922. It was a development of the BH-3 fitted with a Hispano-Suiza 8 engine in an attempt to improve the aircraft's performance. To accommodate the new powerplant, the forward fuselage was considerably redesigned, and the structure in general and undercarriage in particular were strengthened. Performance was found to be only marginally better than the BH-3, and development was quickly abandoned.

Development did not advance past the stage of construction drawings and scale models. The design was passed over in favour of the T-35 project which was already at the prototype stage.
