One reviewer claims, "This book saved me $200" and goes on to say, "What a great book for learning about Quad Copters. Before reading this book I had researched Quad Copters online and had made a decision of which one I would purchase. I decided to order ths book to ensure I was making the right decision. After reading the book I discovered that the Quad I decided on would have been difficult for me to start with ( I have no prior Quad expense). The book helped me choose the correct Quad for my experience level, for what I plan to use it for, and for the pros and cons of Quads built in countries like China. I purchased my first Quad and am very happy with my choice. This book saved me over $200 that I would have spent purchasing the wrong Quad Copter. I highly recommend this book for anyone considering their first experience with Quads".
At under eight bucks and with a decent glossary, it may be worth picking up.
