Handley Page Hinaidi#Variants

In 1923, Handley Page designed and built a new heavy bomber based on its W.8 airliner, the Hyderabad. The Hyderabad was an all-wooden biplane powered by two Napier Lion engines.Jarrett 1993, pp. 19–20. Forty-five were built, entering service from 1925.Thetford 1993, pp. 19, 23.

The Hinaidi was an improved version of the Hyderabad built to meet Air Ministry Specification 13/29. The first machine, the HP33 Hinaidi I -in fact an early production Hyderabad, J7745, with another engine and a change of fin and rudderClayton 1969, pp. 52–53.- first flew on 26 March 1927.Mason 1994, p.199. At least four Hyderabads were converted to Hinaidi Is, while six late-production Hyderabads were completed as Hinaidi Is, retaining the wooden airframe of the Hyderabads. The first true Hinaidi, the HP36 Hinaidi II, went into production after major structural modifications were implemented, the structure being changed from wooden to metal.

A re-engined version with two 480 hp Siddeley Jaguars was proposed, the HP44 Hinaidi III, but not built.

The first 33 aircraft came into service in 1929, and were issued to No. 99, No. 10 and No. 503 squadrons. Total production ended with 36 aircraft, with some being converted to transport aircraft on the North-West Frontier in India. The Clive II transport version operated out of Lahore.
