Design and development
The conversion commenced in December 1950 and the Sparrowjet first flew on 14 December 1953. Other modifications included a new tail section and front fuselage (in place of the Sparrowhawk's single engine), fixed, faired-in undercarriage and a large clear canopy. The wing roots were modified to take the Palas engines.
Air racing history

The aircraft was modified to the order of Fred Dunkerley and he flew the Sparrowjet in air races from 1955. He won the SBAC Challenge Cup at Yeadon, West Yorkshire in 1956 and the King's Cup Race in 1957 with a top speed of 228 mph (367 km/h). The Sparrowjet was severely damaged in a hangar fire at Upavon, Wiltshire in July 1964. In 2004 it was under rebuild in the Bristol area using discarded components from the 1950/53 conversion.
