Are the measurments the same for both sides? It may be due to the perspective of the photo, but I wonder... Check the dimensions for both sides. They should be equal, and the struts are to maintain dimension, not alter the dimension and cause the wing panel to move. Hope this helps.
No they are not the same, that's what make it difficult to measure, This bi plane is 25 + years old, but in exellent shape. and wings are made of foam. but I think with all the info I got so far I should be able to solve this now.
I can see this thread, solving many problems, if one thinking head is good, many is got to be better.
Thanks To all of you.
