VStab was not symmetrical; i.e., if you cut a cross-section in a plane
parallel to the floor and looked at it from above, you'd see that one side
was considerably less convex that the other.

Jim, Lack of a symmetrical profile could be  a problem.  The more convex surface probably may lift sideways more than the other side, causing a yaw that needs to be compensated for.

The Vertical Stab on the IV was fairly symmetrical, as I remember it.

On the other hand, the P-forces of the prop sweeping in a spiral motion around the tail probably do the same thing....Bottom Line:  What does the factory support say?
