Images of the Bi-Mono under test at A&AEE Boscombe Down, November 1941. Note guard rails on the tailplane. Could the small fairing behind the pilot on the rear of the cockpit fairing be a parachute for spin recovery?
A view of the Bi-Mono in biplane configuration. Note the differences in the shape of the upper and the lower wing. Also, it would seem that just like the full-scale Hurricane that followed, the ailerons on the Bi-Mono needed enlarging.
