In 1916 he was part of the project team as chief draughtsman who designed the 150 hp S.E.5, and its follow up, the S.E.5a which arrived several months later with the same basic designs, but a more powerful 200 hp engine. In 1917 he left the Royal Aircraft Factory and joined the aircraft division of Austin Motors as chief engineer and designer in 1918. He specialised in small light aircraft, designing the prototypes of the Austin Greyhound, the Austin Whippet and the Austin Kestrel, but were not developed further by Austin Motors. In 1922 he joined Westland Aircraft Works and was chief designer at the Aircraft Disposal Co. in 1923. By 1930 he had designed the Robinson Redwing, which was built at the Robinson Aircraft Company in Croydon and was designed for flying clubs and private use.

The aerodrome was also purchased and used as the new flying base. In 1934 the Redwing Aircraft Co., moved back to Croydon aerodrome.
