The first prototype He 72A ( registration D-2574) (also He 72 V1 ) took off in the summer of 1933. It was powered by a 103 kW Argus As 8B air-cooled inverted four -cylinder with a two-blade wooden propeller . The successful tests were followed by the production of 20 He 72A-1s intended for the German air clubs of the Deutsches Luftsportverband.

The unreliable Argus engine was replaced in the next version of the He 72B by the proven seven -cylinder Siemens Sh 14A with 118 kW. It saw the greatest expansion in the He 72B-1 subvariant , which began to appear at Luftwaffe pilot schools from 1935.

Since the flight of the He 72 prototype, a float variant was considered for training flying from the water surface. The seaplane was realized in the form of He 72BW (D-2589) with two duralumin floats. Although it did not see serial production , it became famous for participating in the expedition of travelers Schulz and Kamphenkel to the Amazon .

Development continued with an improved variant of the He 72B-2 and a purely civilian derivative from it in 1936, the He 72B-3 Edelkadett for the NSFK National Socialist Air Corps with hooded undercarriage wheels.

The He 72C version with improved chassis suspension and the He 72D with an expanded set of navigation instruments were created as prototypes or smaller series . Modifications of variants C and D were continuously applied in mass production of the B-1, and new versions were not introduced.

Before the war, the Kadettas flew mainly with the NSFK, from where they transferred to the Luftwaffe after 1940. The He 72 B-1 operated with at least twenty-five schools and training units, for example A/B 6 in Gdańsk , Ausbildungsregiment 5 Seerappen, A/B 11 in Schönwald, A/B 24 Olomouc , A/B 32 Pardubice , A/B 43 Metz -Diedenhofen, A/B 62 Vöslau, A/B 72 in Detmold , etc.

The Slovak Air Force took over 30 generalized He 72B-1s, which were then designated as D. Another six B-1s were already taken over by the Bulgarian Air Force in 1936, where they received the name Kanarče and served here until 1944 for basic training.

After the war , two He 72s were preserved in the territory of the restored Czechoslovakia , which were designated C-12 by the air force . Later they flew as civilian aero clubs.
