Ray's Helicopter manual - Big Problems!
I do not think there is "one" good book for rc-heli out there. I think rays manual is good for the basics and explains things well. And like with a lot of things, there is always more than one way to do things and any book or person will base it on their personal experience. Talk to 10 people how to setup and fly a heli and every one will tell you something different, except the very basics.
You just had bad luck with the pages "together" that can happen with any book.
As for the corrections, since rc-control is a small market and the publisher wants to keep the cost down, I guess they decided to add those pages instead of a complete new setup (and high cost) for some minor changes
