The model contains two patterns as shown on the picture.
The Imperial Japanese Army (IJA) developed the Ka-1 autogyro for reconnaissance, artillery-spotting, and anti-submarine uses. The Ka-1 was based on an American design, the Kellett KD-1A, which had been imported to Japan in 1939, but which was damaged beyond repair shortly after arrival. Kayaba Industry was tasked by the IJA to develop a similar machine, and the first prototype was flying on 26 May 1941. The craft was initially developed for use as an observation platform and for artillery spotting duties. The IJA liked the craft’s short, (30 m (98 ft)) take-off run, and its low maintenance requirements. Production began in 1941 and the first autogyros were assigned to artillery units for artillery spotting, crewed by pilot and spotter.

Production began in 1941 and the first autogyros were assigned to artillery units for artillery spotting, crewed by pilot and spotter.
The prototype Ka-1, essentially a repaired KD-1A powered by a 240 hp (180 kW) Argus As 10c, shared similar aspects to the Focke-Wulf Fw 61, which was first flown in 1936, but only about 20 were produced.
Production continued as the Ka-2, powered by Jacobs L-4MA-7 engines, similar to the Kellett KD-1. During production, a shortage of critical components for rotors and engines resulted in severe delivery delays.
A total of 98 Ka-1 and Ka-2 airframes were produced by the end of war, of them 12 were destroyed before being delivered to the IJA, around 30 never had engines installed. About 50 were delivered to the IJA, but only 30 were actually deployed. Some sources have stated that 240 were built, but this cannot be verified. |
