If you have the kit the instructions say to lay the wing upside down on a flat surface and join the wing halves pg#3 para#11! I have built a number of the bridi xlt/escape aircraft so if you cannot lay a straight edge acrossn the top of the wing me thinks that you may missed that page in the instructions!


maybe flat is the wrong term you can lay a straight edge across the top off the wing and there should be no gaps
