The Arado Ar 69, a two-seat German beginner’s school and sport biplane with an open cockpit, was developed in 1933.
There were three prototypes constructed: the Ar 69 V1 and Ar 69 V2 were equipped with 78 kW (105 hp) Hirth HM 504A engines, while the V3 had a BMW Bramo Sh.14a radial engine.
The V1 and V2 were intended to be the Ar 69A production models, while the V3 was meant to be the basis for the Ar 69B production version.
However, no production aircraft were manufactured as the Focke-Wulf Fw 44 Stieglitz, a rival aircraft, proved to be more successful.
