Flight tests were conducted at the Flight Test Station of the Pilotless Aircraft Research Division at Wallops Island, Va., to determine the longitudinal stability and control characteristics of 0.5-scale models of the Lark pilotless aircraft. The investigation included tests of the standard configuration (tail surfaces interdigitated with respect to the wings) having the horizontal wing flaps deflected 0, 15, and 60 degrees and a test with the tail surfaces in line with the wings with wing flaps not deflected.
