Great Paper Fighter Planes

This is a great book; my seven-year old son and I have been working our way through it. So far we've only made a couple of planes, but they do actually fly, just like it says. There's enough detail in the book that it's almost worth it alone just for the time he's spent trying to read it. There are a couple of things to note. The planes are built by copying plans onto a sheet of paper, gluing the paper to a blank 5x8 index card, and then building up the model with layers of cut-out pieces. This makes for durable planes, but allow an hour or more per plane for construction. Even on rough concrete the planes will survive many crash landings. 1.) Krylon spray adhesive works great for gluing the copies onto the index cards, although the copies just barely fit so make a few extra. 2.) For cutting out the planes a sharp #11 X-Acto style knife blade is really handy. 3.) Standard glue sticks work great for building up the layers, but take a while to dry ... several hours to overnight is best depending on temperature and humidity. 4.) The stabilizers aren't quite as stable as they might be, and so planes do flutter if thrown too hard or in a stiff breeze. 5.) I have the hardcover edition, which folds flat for copying; this is important, and I don't know if the soft cover does the same thing.
