Hawker Tomtit

The type was designed in 1928, a two-­seater trainer biplane with a 130 hp Armstrong‑Siddeley Mongoose III engine with five cylinders, a top speed estimated at 120 miles an hour and a cruising speed of between 85 and 90 miles an hour. As a replacement for the Avro 504N for RAF pilot training, 25 were supplied to the RAF between 1929 and 1931. The last, K1786, was delivered in January 1931. They entered service with No.3 FTS at Grantham and the CFS at Wittering but the type were relegated to communications tasks from 1935. Six Tomtits were used for communications duties during the war and two, as G-ABII and G-AFTA survived post-war. G-ABII was written off in 1948.

A total of 36 were built for the RAF, for civil registration and for export to Canada and New Zealand. The last Tomtits left the RAF in 1938. Civil and ex-RAF Tomtits were fitted with a variety of engines, including the ADC Cirrus Hermes and Wolseley Aquarius and were used by several aero clubs up to the out-break of the war.
