Avro 566 Avenger

Aerodynamically one of the cleanest fighter biplanes of its era, the Avenger, designed as a private venture by Roy Chadwick, was first flown on 26 June 1926. Of wooden construction with fabric skinning, the Avenger was initially flown with a 525hp Napier Lion VIII engine, but no order was obtained, and, in May 1928, the aircraft was modified for racing purposes. It was fitted with equi-span wings of 8.53m, streamlined I-type interplane struts, ailerons on both upper and lower wings, and a 553hp Lion IX engine. In this form it was redesignated Avro 567 Avenger II. Various progressive developments were proposed, but none saw fruition, and the Avenger was dismantled for use as an instructional airframe in 1931.
