I haven't had any problems at all with mine. I did add an extra hingpoint down towards the bottom of the rudder. I now have a hingpoint slightly above the control horn, which was originally the lower-most hingepoint as drilled at the factory, and I have a hingepoint, the one I added, just below the horn. I imagine it would have been fine without the additional hingpoint, but, because of my set up, I liked the idea of having a little extra strength at the horn.
