The Badminton was a single-seat single-engine equal-span biplane, it was made from wood and metal with fabric covering.[1] It had a conventional tailskid landing gear and the nose-mounted engine was a 510 hp (380 kW) Bristol Jupiter VI.[1]
Only one aircraft was built, registered G-EBMK, and it first flew at Filton Aerodrome on 5 May 1926.[1] It was entered into the 1926 King's Cup Race but it forced-landed with a fuel feed problem.[1] In 1927, the aircraft was rebuilt as the Type 99A with new wide-span tapered wings, a raised centre section and wide-chord interplane struts.[2] It was powered by an uncowled (525 hp) (392 kW) Bristol Jupiter VI engine.[2] It gained a certificate of airworthiness on 26 July 1927, but had a fatal crash at Filton two days later (28 July) after an engine failure on takeoff.[2]
