The
Kadett was designed in 1933 to meet an official requirement for a basic trainer. It was a single-bay biplane of fabric-covered, metal construction with open
cockpits, a
staggered wing, a strut-braced
tail unit, and fixed
tailskid undercarriage. The
prototype was powered by a 104 kW (139 hp)
Argus As 8B air-cooled
inline engine. The first production model, the
He 72A retained the As 8B engine in early batches, but later production aircraft had a 112 kW (150 hp)
As 8R. The
He 72A was superseded by the
He 72B, which was the major production version. This was powered by a 120 kW (160 bhp)
Siemens-Halske Sh 14A radial. The
He 72B was produced as the
He 72B-1 landplane and '
He 72BW Seekadett
("Sea Cadet") twin-float seaplane. The civil development was the He 72B-3 Edelkadett''''' ("Noble Cadet"). ==Operational history==
