Wing sweep, yes. Flying RC models years ago I found that I could roll an aerobatic plane having no dihedral at all, but about 5 degrees of sweep, using rudder alone. I once launched the thing with the aileron servos disconnected, but recovered it that way. Wasn’t pretty, but I got it on the ground in one piece.
As a flight instructor on the B-727, I taught the “Dutch Roll” recovery procedure.
Dutch roll is caused by wing sweep and instability of the Yaw axis.
It is not comfortable because the nose of the airplane moves in a way to trace a figure 8, lying on the horizon. If the recovery procedure is not done properly the result could be loss of control of the airplane. The recovery is done with the pilot’s feet on the floor, (no rudder inputs, at all) and the forward movement of each wing dampened by small inputs of the spoilers on that wing.
I taught the recovery in simulators and also in the airplane.
The B-727 had two yaw dampers, on the rudder, powered by separate hydraulic systems. If one hydraulic system failed, the airplane had to descend to an altitude below 26,000 feet, to fly in more dense air where the Dutch Roll was unlikely.
