Flight, November 1928

BERLIN AERO SHOW 1928

Two Russian Machines

<...>
   The Russian ambulance 'plane, type K.4, was a high-wing, strut-braced monoplane, apparently of mixed construction, as although the fuselage was a tubular structure, the wing was fabric covered and apparently of wood construction as regards its main structure.
   The internal arrangement of the fuselage was such as to permit of a stretcher case being accommodated, with a doctor or nurse in attendance. The engine fitted was described as a 300 h.p. M.6, but had all the appearances of being a Hispano.
   The particulars of the K.4 given on a placard were: Tare weight, 1,420 kg. (3,125 lbs.); ambulance load, 640 kg. (1,410 lbs.); Maximum permissible load, 1,000 kg. (2,200 lbs.); gross weight (maximum), 2,420 kg. (5,325 lbs.); maximum speed, 185 km./h. (115 m.p.h.); cruising speed, 160 km/h. (100 m.p.h.); landing speed, 70-75 km./h (44-51 m.p.h.); climb to 1,000 m. (3,280 ft.), in 5-5 mins.; to 3,000 m. (9,840 ft.) in 21 mins.
