Check to see if there is a warp in the wing.

If you hold the wing out at arms length parallel to a line between your two shoulders, you can sight down the trailing edge and see if there is a warp. Follow the trailing edge line and the spar line. If there is a warp you will see more of one side of the wing than the other. Keep your head still and move just your eyes.

If you're not sure, go by the local field or seek the advice of a good builder. Take the fuselage with you as well.

A good builder can fix just about anything. So don't worry, all is not lost.

I bought a 1/4 scale Giles Where the original owner built the wing upside down. The person I bought it from did a beautiful job of repair, Then he glassed the center section. This plane has been through some of the most violent maneuvers you've ever seen

This thing flys so sweet. He took the time to make sure everything was perfect, and it shows! Pattern maneuvers are just awesome.

I'm sure yours will come out great too. Just be patient.

Best of luck,

Scott
