THE ROUND-GERMANY FLIGHT

THE MACHINES

Udet-Flugzeugbau G.M.B.H.

   Although one of the younger German firms, the Udet works of Munich have shown quite surprising energy since the foundation of the firm a few years ago. In the Round-Germany flight a considerable number of machines are entered, most of which have been described in FLIGHT from time to time. At least one new type has been produced for the competition, and curiously enough this is a biplane, the U.12 - so far as we are aware, the first biplane to be produced by this firm.
   To deal with the Udet machines in the order of their series numbers, the U.7 is a light monoplane with British Douglas engine. The machine has previously been described and illustrated in FLIGHT, and is shown again this week in a photograph and a set of general arrangement drawings. The fuselage is of the ply-wood covered type, and the cantilever monoplane wing is mounted parasol fashion above the fuselage, on pyramids formed by streamline steel tubes, so that the pilot sits under the wing, where, consequently, he has an excellent view in all directions except straight upwards.
   Already the U.7 ("Kolibri") has several excellent performances to its credit, and it may be expected to do well in the competition. Its main dimensions are: Length o.a., 5.47 m. (17 ft. 11 ins.); span, 10 m. (32 ft. 10 ins.); wing area, 12-5 sq. m. (134 sq. ft.). The weight empty is 150 kg. (330 lbs.); useful load 100 kg. (220 lbs.); total loaded weight 250 kg. (550 lbs). The top speed is 120 km./h. (75 m.p.h.) and landing speed 50 km./h. (31 m.p.h.).
