Well there you go. Coolest book I've read all year, this is the book I've been searching for (kinda of). I love space, I love rockets, and I really like model rockets because I didn't go to college. This lil' bible here is easy to read and fallow and filled with answers to so many questions, many that I hadn't even been asking. I almost put the thing down after the first two chapters, I was all "I know this shit, ugh", yep I thought I had wasted my 18 bucks, but no, oh no. This book is filled with the equations that I have been dying for and they're explained it about as straight forward as you can get. So, ya know, if you fly model rockets and haven't read this book you're doing yourself wrong.
