Excellent tip ddubya! I never thought of that one.

I've built lots of wings and just finished one that is not only warped, but skewed as well. It was straight when I was building it, but I think when I put on the trailing edge sheeting I skewed the wing as it was still very flexible.

Anyway, it was uncerimoniously crunched up into a little heap of balsa and disposed of. The bad part is this wing has about 36 rib/half ribs in it and I had to cut out another set.

But the important thing is that it will be right when it's done. Much better to get it right than to fly a crooked airplane.
