my tank stopper failed also and filled the inside with fuel. My tail feathers are now twisted about 5-10 degrees. Sure looks funny but still flies great.

If you are going to just fly in circles, you do not need to glue the wings together. Anything more and you need to glue the wing halves together.

I glued my wings and they still separated slightly during basic aerobatics. Luckily I noticed before another flight. I re-glued them and glassed the halves together. No problems since. If you don't glue the wings together and they separate during flight you will have nothing to repair.....

It really is a tough plane. It is like that old VW bug that everyone's parents had in the 70's.
