Konstantin A. Kalinin began work on the K-1 in 1925 at the Kharkov aviation institute. Kalinin's closest collaborators included Dmitri Tomashevich, Alexey Nikolaevich Grazianski and AT Rudenko. The first designs had been drawn by Kalinin as early as 1923, when the Ukrainian airline Ukrvozdukhput had demanded a cheap, robust and easy to maintain aircraft, after the opening of the first regular flight from Moscow to Nizhny Novgorod. The K-1 was a high-wing strutted monoplane with elliptical wooden wing covered with fabric. The fuselage consisted of a tubular steel frame with aluminium sheet covering to the rear of the cabin and fabric covering the rear fuselage, constructed was carried out by RVZ-6 (RVZ - Remvozdhukozavod - factory) at Kiev. After the first flight, on 20 April 1925,[1] factory testing took place over the Summer, and in September 1925 the K-1 carried out state acceptance trials at Moscow, reaching a speed of 191 km/h (119 mph; 103 kn) with full load at 3,000 m (9,800 ft).[2]
After the K-1 was put into use, the designers came very quickly to the decision, to replace the 170 hp (130 kW) Salmson RB-9 engine with a more powerful and modern engine. Several engines were considered, but Kalinin and his group ultimately opted for a 240 hp (180 kW) BMW IV engine.
