If I may, please get something like an msr to start with and learn orientation in your living room. Once you master that, move up to the mcpx or 130x and learn what collective pitch is all about. The 800 Trekker is a lethal helicopter. I have seen many first flights, and they are all over reacted. I urge you to start out with something smaller for safety sake. A 450 is the largest I would go when learning. One crash with a Trekker is going to cost somewhere at least $200 or more if it hits someone.
With that said though, we are here to help you get it setup if that is really what you want to do. I don't suggest it, but we will help. Just post up in teh helicopter section in the forum (we try to keep questions out of the introduction area since you will find more help in the tech section) and we will help you get it going.
