Not sure if this is what you are talking about but I have seen the ele and stab droop downward or upward when the ele is deflected. Either the stab TE or the ele LE isnt straight. Cut it off and sand everything true and rehinge. When hinging just slip hinges in both surfaces and deflect surface both ways to ensure the right amount of gap between the two then ZAP em!(pink Zap that is) Hope this helps. If I am totally out of the ball park on what the problem is I'm sorry.......John
