They were thick in section and strongly cambered at the root, thinning steadily outboard, and had 8° of dihedral.
[1] In 1922-3 the Phönix was flight tested at Stralsund and at Rossiten, one base of the RRG and a home of German gliding in the 1920s.
[1] Some of these take-offs were made under wind power alone, with the Phönix moored to a buoy on a long, down-wind cable and rising like a kite.
[2] In 1923 Flight referred to it as the Phönix 3[3] but nothing is known specifically about earlier models, though there are some differences between the g/a diagram and images, particularly for the rudder profile.
