This is my first model and I have made a few small mistakes. It's a Fiddlersgreen Fokker DVII. One big success I had was the lower wing. I put it together and it turned out very nice. I'm having some trouble with the upper wing however. Any tips or problems in the design I should watch out for? It seems when I bring the trailing edges together it's in the wrong place. It seems like the trailing edges are in the wrong spot. Unless I am missing something.
