Albatros L 75

The German trainer biplane of the 1920s, known as the Albatros L 75 Ace, was a conventional aircraft with separate, open cockpits for the pilot and instructor.

Its wings were single-bay, equal-span, and featured a slight stagger.

Even after Albatros was assimilated by Focke-Wulf, production of this aircraft continued.
