I'm building a Twist and was putting the stab in the slot to mark it and get ready to glue it. Well, I centered it in the slot perfectly. I went to measure from the stab tip to wing tip and it's off by 1/2 inch. Puzzled I was. Well measured from the wing tip to the front of the fuselage and pretty much dead on. HMMMM.... Then looked down the fuselage and bingo. The tail is off. The whole ass of the plane is crooked, to the right by 1/2 inch. Damn!!!! What should I do? Is this a major flaw to try and get it replaced or will it be ok? It's excactly 1/2 inch. Won't that throw the rudder off too? What should I do!!!!!!
