O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

Kondor B I
   Built for training duties with a large communal cockpit, the Kondor B I was type tested in January 1918. It was a conventional two-bay biplane of wooden construction with a ply-covered fuselage. Large "ear"-type radiators were accommodated on the fuselage sides, and ailerons were fitted at all four wingtips to afford sensitive lateral control. This aircraft pioneered the principles of simple construction: minimum number of parts needed, interchangeability of components and some pre-fabrication. Engine, 120 h.p. Mercedes D II. Weights: Empty, 806 kg. (1,773 lb.). Loaded, 1,150 kg. (2,530 lb.).
