During the year before the start of the 1918 conflict, the idea of a specialized type for use as a fast scout in war had taken firm root in the minds of several designers; among them, A.V. Roe, who had by this time given up most of his active flying to concentrate upon design. His thoughts up- on the subject appeared in the form of the "Arrowscout," the new machine being shown on the Avro stand at the 1914 Olympia Aero Show, where it was seen to embody a number of original and advanced ideas. A single bay biplane layout was adopted, with considerable sweep back being used on the wings, the lower surfaces of which were flat. Slight dihedral was incorporated and the upper and lower wings were connected by single close-set pairs of light-weight interplane struts which were faired between with fabric to form "I" struts. "N" center-section struts formed the rest of the wing supporting structure. Another unusual feature was the fitting of air brakes at the lower rear wing roots,

consisting of rectangular trailing edge sur- faces which were hinged at their centerlines to stand vertically across the airflow.
