A fabric-covered all-metal single-seat shipboard fighter designed by Harold Bolas to Specification 21/26, the Pipit equi-span single-bay staggered biplane was powered by a 495hp Rolls-Royce F.XI 12-cylinder water-cooled engine and could be fitted with either wheels or floats. The first of two prototypes was flown in 1928, but crashed when a tailplane spar failed as a result of flutter. The second prototype, with a 520hp F.XIIS engine and many other changes, was also lost as a result of violent flutter which fractured the sternpost whereupon the vertical tail surfaces were carried away. Further development of the Pipit was then abandoned.
