An N.A.C.A. 23012 rectangular wing with rounded tips was tested in combination with a fuselage of circular cross section at several angles of yaw in the N.A.C.A. 7- by 10-foot wind tunnel. The model was tested as a high-wing, a midwing, and a low-wing monoplane; for each wing location, tests were made with two amounts of dihedral and with partial-span split flaps. For each combination of wing and fuselage, tests were made with and without a fin. Sample charts of the coefficients of rolling moment, yawing moment, and lateral force are given for some of the combinations tested. THe rate of change in the coefficients with angle of yaw is given for stability calculation.
