one of the guys here- new zealand- was forseeing all sorts of troubles aligning veetails . decided to solve the problem by making the joints in the tailplane directly above the fuselage sides in plan view.....otherwords the joints (2) were directly above the exterior faces of the fuselage sides. this enabled the centre section of the t/plane to be parallel with the wing/ engine. simple system and worked very well. regards trevor h[8D]
