RE: warped spitfire wing

ORIGINAL: ablais007

I have built a TF 60 size spitfire... Somehow the main wing is twisted on one side...This is a fully sheeted 1/16 balsa wing.
I am wondering if anyone has some tips on how to straighten the wing... I was thinking of using alcahol and water to soak the wing skin and use wieghts.

Any other techniques out there?

Thanks.

Determine HOW MUCH twist you need to remove. Then wet the wing half you need to straighten.

Cut some thin slots in the sheeting (about 1/16" wide - 2 or 3 on each side will be fine ) to allow the sheeting to shift without buckling and cracking (hopefully ).

Next, weight the wing down with zip lock bags filled with sand. Slide shims under the side/area you need to straighten. Let dry for a couple of days.

Remember to shim it a little more that what you actually want since the wing is going to "rebound" a little when all the weight is removed.

Fill the slots with light weight filler and sand flush/smooth.
