Many moulded kits including Fiber Classics, Airworld and Skymaster that I have built have extended trailing edge surfaces on wings, tail plane and rudder its simply a matter of trimming a couple of millimeters from T.E. overhang to allow control surfaces to butt up against rear edge of wing etc. Its normal and common place and is part of building many composite kits now days.... Even on some older kits going back to Byron days this was the case ie Byron Mig 15
