Spending lots of money for molded planes is no assurance that they are absolutely straight, flat or square. In any manufactured item there are "production tolerances". I have no idea what the tolerances or acceptable deviations are, or should be, for molded models, but I've certainly never seen any published by the manufacturers, who are so small they are unlikely to have a QC manual. To be honest, I have no experience whatsoever with molded wings, but I have some experience with fiberglass fuselages which commonly have bends, twists or corkscrews built in - at no extra cost. What you did with your Eclipse makes sense and yes, the "experts" do it as a matter of course. I do wonder if the "wash-in" along the entire trailing edge isn't actually reflex on the airfoil that's supposed to be there? Comments from other Eclipse owners?
