Hinaidi J9033 was experimentally fitted with metal structural members in the fuselage in place of the usual spruce. It was also used for trial installations of armament and radio equipment at Martlesham Heath.

The main difference between the Hinaidi and the Hyderabad was the engines. The Hyderabad, seen here, was powered with two 450 h.p. Napier Lions; note the rectangular radiators. The major production versions of the Hyderabad featured metal instead of wooden construction.

Hinaidi J7745 was one of two prototypes - J7741 was the other. Both were converted from Hyderabads and J7745 made its first flight on March 26, 1927 from Martlesham Heath. This photograph was taken at the 1927 Pageant at Hendon.
