Wayne, it sounds like you are thinking of hinging the Stuka like any other plane. This is not scale for the Stuka, they had their ailerons and flaps suspended beneath the trailing edge. Look at your plans more carefully, specifically the sheet with the wing center section. There are some profile shots of the dive brakes and the ailerons. I suggest you study your plans more Wayne. Thats the one thing that I hear the most from the more experienced builders, is study study study your plans. When you see the diagram youll say to yourself "Ah I see how it works now". You'll get it Wayne, no problem!!
