Avro 566 Avenger

Avro 567 Avenger II

Designed as a private venture by Roy Chadwick, the Avenger fighter was first flown on 26 June 1926. Built of wood with fabric skinning, The Avenger was initially flown with a 525hp Napier Lion VIII engine, but no order was received.

In May 1928, the aircraft was modified for racing and redesignated the Avro 567 Avenger II. 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. Various progressive developments were proposed but the Avenger was dismantled for use as an instructional airframe in 1931.
