I've been lucky and haven't run into any major snags. There is some small gaps in places, but nothing a little putty and sanding won't take care of. I've got the wing landing gear done on one plane so far today. I'll get back to the other one after dinner.
What was for dinner in your parts of upper state New York. You did say you're from Buffullo, New York? We had five hour roast pork that gets shredded and pan fried with rendered fat and cabbage. And some California hand rolls. Dessert was my world famous Chef Toshi's cheesecake.
Don't worry too much about the PE as oppose to things like sanding the seam down and aligning the wings and tail. Those are much more visible than PE. PE is to car wax as to building the engine block properly is to assembling the model without any seams. You know what I mean! LOL! Everything is looking fantastic!

P.S. I wish my stuff looks as good as yours, you make me want to quit!
