In 1925 he designed an all-metal plane, the single-seater fighter Avro Avenger and in 1926, the Avro Avian in which Bert Hinkler flew the first solo flight from England to Australia in 1928. In 1928, he moved back to the Avro factory in Woodford, Greater Manchester, used by BAE Systems until its closure in 2012. That year, he designed an eight-passenger high wing plane, the Avro 10 and a four-passenger version, the Avro 4. In 1929, he designed the RAF trainer, the Avro Tutor, a smaller version, the Avro Cadet and an enclosed version, the Avro Commodore. This was followed by the Avro Anson, used in World War II for training crews and as transport aircraft.
