After I test fitted the rudder, I had troubles installing the washers above and below the hinges. The rudder appeared not to be sitting straight on the hinges. I ran a string line down the three hinges on the rudder and they seemed to be aligned very well. ( Photos below ) The three hinges on the vertical stab. were not aligned very well. It took a little time to decide the number two hinge was not correct causing the alignment issue. Des was in JNB and picked up a new hinge last week. I removed the old hinge and replaced it with the new one and the issue was solved. The rudder now self centers beautifully, its a shame I will have to remove them for painting.
