Force and tuft tests were made on a model in original condition with wing tips rotated for washout, with rectangular and swept-forward tips, and with various slat arrangements. Most promising modification were flight tested. Results indicated that changes in tip plan form or rotation of wing tips did not reduce instability at high lift coefficients. Addition of wing slats improved the longitudinal stability at the stall when slat extended far enough into area that stalled first.
