I am building the ultrasport 40+ and have run into a snag on the left wing. After I got all the ribs, spars, shear web, and trailing edge together, I lined the wing up on the plans as per instructions and weighted it down to hold the wing flat. After I got all the joints glued and dry, I took the weight off and knoticed that the trailing edge would not lay flat. After inspection I found that the die cut trailing edge had a bow in it. In other words, the triling edge has a crown in it in the same way you would look down the edge of a piece of 2x6 lumber. Do you think I will be able to build that bow out with the sheeting etc.

I made several kerf cuts in that area from the bottom up (the part of the trailing edge that was to be cut off any way after sheeting was done). That allowed the wing to stay flay after the 3/4 by 1/16 trailing edge sheets were glued in place. I was afraid that I was going to have to get all the parts for that half of the wing and build another.

Thanks Bax
