One hint: the X-Plane OBJ importer does not merge vertices on import. Merged vertices are when one vertex is connected to multiple surfaces (such that dragging the vertex deforms two faces at once). Merged vertices are needed for smooth shading to work, because AC3D has to know that the two surfaces are meant to form a continous curved surface. (The technical term is probably not merged vertices....but I'm not sure what it is. :-)
So anyway, after import, select your object and pick "optimize vertices" from the Object menu, then hit the 'smooth' button and it should look good. Smooth shading is WYSIWYG from AC3D to x-plane.
One other note: crease angle is exported properly and does not create an attribute, so your best bet for framerate in an object with smooth and non-smooth shading is: set crease angle correctly, set the whole object to smoothed shading, and expor that way.
*Cheers*
