Mattnew.....You can find the exact center of the tube and (lightly tap) the center with either a screw driver or chisel. The indent will cause the tube to take on a degree of dihedrel when the wings come together. You will have to adjust the wing strutts as the wings with the new dihedrel will pull away slightly from the fuse. I did this to my plane and the strutts just needed a slight amount of adjustment. It looks much better(IMHO)! The full scale does have some dihedrel while it may be also possible some full scale planes (by adjustment) may have none.[ATTACH]2001826[/IMG]
