Boompa, Hears an idea on how to straighten the wing. Get two straight 1/4 round dowels. Tape one on each wing tip to the bottom of the wing where they stick out the front of the wing like gun sights. On a big stick, the bottom of the wing from the spar to the trailing edge is flat.

Hold the wing up to your shoulder like a rifle and sight down the sticks like you are aiming a rifle. You should see how far off the alignment is.

Now, get someone to help you. Let them hold one wing tip firm while you twist the wing to line up the gun sight sticks. You will see wrinkles form in the covering.

Take a heat gun used for shrinking monokote and shrink the wrinkles out of the covering. Keep doing this until the gun sight sticks line up together.
