Why cut up the wings if they don't need replacing, just send them the fuz and they can send you back just a fuz if it was a material defect. As far as the last post goes the tail just bolts on and no removing of covering is required, did you bolt yours on or glue it. I am in the middle of putting mine together and when I was bolting on the stab I was thinking it would be easy to over tighten the screws and crush the stab possibly causing a weak point right at the fuz. Good luck and I hope it works out and I hope I don't have the same out come with mine. Brian Billings
