You really shouldn't need a book. If this thing builds anything like I've heard, you shouldn't have any problem. Just do yourself a favor.... READ the instructions! And I don't mean just as you go along, I mean read them in bed, read them in the bathroom, read them any chance you get. Understand the steps before you glue anything. If there's something you don't understand, look through the parts and see if that helps. If you're really stuck, call up a buddy and get him to come over and show you what they mean.
And don't get too upset if you make a mistake. We all do. That's why God invented balsa filler!
