Each one is just a bit off until at the outboard rib, the error is about 1/4". I can build it with the notches as a guide. I am sure the cut wood is accurate as all of the spars, trailing edges and leading edges all line up. I was just curious if anyone had seen plan shrinkage with old kits. This one must be about 15 to 18 years old. I personally would not have built it, rather collect it, but my kid bought the kit and asked me to build it for him for Christmas. Why not, the one I originally built is just about restored, so we can have two "old" maiden flights the same day
