I have hear two other cases with the same problem and result...
the problem, as they told me, was that the two Anti Rotation Pins werent secured into the wood work, which was light balsa (not adequate enough for the elevator), very little glue on any joint has results in the 8mm Shaft twisitng out of the stab structure.
hope this help you understand what went wrong...

This is exactly what was meant by my post
So to prevent this from happening you ("you" meaning anyone who purchases a model) need to cut open the stab to inspect/repair, now I realize that this shouldn't be required by the modeler and the manufacture "Should do it right the first time", but it has been proven in the past to be a week spot.
With that being said, IMHO due diligence as a pilot of "YOUR" model requires you to verify this potential weak spot before flying said model.
