The book.
No I dont believe anyone, in this forum at least, will require the book. That said it is a nice book as i like any book, except romance novels, that has airplanes in it. I am always in search of tips though, so I guess like any other modeler , maybe, if I can find one tip that makes my builds nicer and possibly easier then I find it worth it as I have A LOT to learn!
Hoping to buy my LARGE TYPHOON soon. Hey that rhymed.
