Design and development
The Scout was a decidedly unconventional aircraft - a biplane with a fuselage pod mounted on the upper wing. A twin-rudder tail was attached by four booms, and it was provided with an extremely narrow-track undercarriage. The primary armament was intended to be a 2-pounder recoilless Davis Gun, but this was never fitted. Four prototypes were ordered in 1915 and two each were built by Hewlett & Blondeau and the Blackburn Aeroplane & Motor Company.
Trials flown by pilots of the Royal Naval Air Service at Chingford proved the aircraft to be seriously overweight, fragile, sluggish, and difficult to handle, even on the ground. The project was abandoned and all four prototypes scrapped.
