Duco, Funny story about that Tail decal; I had an ooops moment when covering the tail and split the ultra-cote open with the heat gun. I cut out my mistake and laid a "carefully" planned patch over. well careful as I was, it stood out bad so I decided I need a Navy style tail emblem. The best place I could think of for a quick "cool" sticker was the automotive section of walmart. After hem-hawing over a few others I saw that one. had 2 big stickers on one sheet for the same price as one of the others. I was sold! When you get to build yours, the only real mistakes I had in the instructions or plans was drilling for the wing bolts. The plans are off about 3". The rest you can probably do without the book. (as long as you look at the pictures)
