Find F = [F1 F2 F3 F4] such that the damping of yaw oscillation is increased and the plane still responds decently to pilot commands. More specifically: we want the complex eigenvalues to have real part less than -0.2, and we want there to be a real eigenvalue within 0.02 of zero. [Hint: There is a solution with F1 = 0 = F3 and F4 = -0.09, so you only need to fiddle with F2 to find an appropriate value.]
