Stability and Control Data Obtained from First Flight of X-4 Airplane

Memorandum presenting stability and control data from the X-4 airplane during the Northrop conducted acceptance tests. The data were obtained for a center-of-gravity position of about 22 percent of the mean aerodynamic chord. Results of the flight indicated that the airplane is slightly unstable, stick fixed, in gear-up, flaps-up configuration for a center-of-gravity position at 21.4 percent of the mean aerodynamic chord.
