I am assembling my first kit a Goldberg Tiger 2 and everything was going fine with the wing assembly untill now. everything was aligned perfect , i was using the provided supports to build the wing, the 2 halves were joined without incident. Actually i was just about done with the wing and had it off the table to do some sanding -when i set it back down tonight on the supports i built it on- the right trailing edge corner is about a half inch off the supports and the rest of the wing sits level. what can i do? the wing has been perfect for two days and now its twisted, what causes this, and is my wing beyond hope?
