| 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.
