I found this forum about a week ago and this is my first post. Lot's of great info here. I am building an Sig LT-40. My wings are now joined and I realize that I made a mistake by not checking for wing twist before I finished joining everything. The left wing is good, both spars lay flat as does the trailing edge. The right wing is not as good. On the last 3 rib bays, the trailing edge starts to pick up. At the tip, the trailing edge is up about an 1/8" and the rear spar is up about 1/16". I would hate to tear this area apart because it does look good, but if the flight characteristics are going to be compromised, then I have no choice. Any thoughts?
