I have set up countless planes with my radio over the years but I still have my instruction book on my lap every time I do it. Once I somehow tossed it out and have never figured out where or when so I downloaded one from the net and printed it out. Things like expo is something you will just have to do as trial and error from plane to plane. My radio has expo on the throttle servo too so I use it there but make it more sensitive. I like the throttle to move faster. Keep playing with it and you will find a lot of things you like and don't like to use.
