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?
