Two similar flying views of the tiny 20ft span Hillson Bi-mono, showing it with and without the disposable top wing. It is seen here with the later short-span slip-wing. The Bi-mono was powered by a 200 h.p. D. H. Gipsy Six engine which added to its “sawn-off Percival Proctor" appearance - Hillson licence-built hundreds of Proctors during the war.
