The Venom had a sideways-hinged engine mounting and it was unique in having 90° deflection flaps. A battery of eight 0.303 in (7.7 mm) machineguns was mounted in the wings from the start of test flying. First flight took place at Brooklands on June 17, 1936, pilot was Mutt Summers. The Venom proved exceptionally maneuverable, with outstanding roll rate and turning radius, but it lacked the power to compete seriously with its contemporaries, and, as no sufficiently compact British air-cooled radial of adequate power was available for installation, it was scrapped in 1939.
This aircraft was 'Class B' registered. 'B' registrations were used on aircraft for tests, experiments, CofA-qualifying, CofA-renewal, demonstrations. In this case the 'O' was used by Vickers from December 1929 until December 1947, the '10' dignified the tenth aircraft used by Vickers for 'B' activities. The 'PV' was added by the manufacturer and stood for 'Private Venture'.
