Low-speed tests of a wing swept back 35 degrees at the 0.33-chord line and a horizontal tail located well above the extended wing-chord plane indicated static longitudinal instability at moderate angles of attack for all configurations tested. The present investigation was made to determine whether the longitudinal stability could be improved by use of chordwise fences, by lowering the horizontal tail, or by a combination of both.
