The best thing you can do is read this:

from first to last page. It will answer most if not all of your questions. Setup on these beasts is very important and you'll never get in the air or have any fun 'till you learn at least the basics. I tried to do it all on my own without reading and researching and had no luck and spent alot of money in parts.
