Three Avro IV Triplane (one static) were built in 1964 by the Hampshire Aero Club for the film “Those Magnificent Men in Their Flying machines”. Of all-wood construction and powered by a Cirrus II engine, they were designed by R.Hilbourne. The construction of the triplane followed A.V. Roe’s specifications and was the only replica that utilised wing-warping successfully. With a more powerful 90 hp Cirrus II replacing the 35 hp Green engine that was in the original design.
The first was flown on 9 May 1964. One passed to the Shuttleworth Trust after the film, who kept it airworthy at Old Warden as BAPC.1.
