Serius,
I'm not sure I can answer your question correctly. I believe there are probably many YT videos out there explaining the process but I'll try to give you my experience. I would start with rolls, they seemed to be easier to me than flips. I would start out getting the quad to go in a slow, forward, just past hover motion. Pretty much leave the throttle where it is and quickly start a roll motion, you have to almost snap it to the right or left. As soon as you start to see yourself upright again let the stick go. In Horizon mode if you're off a little bit it will attempt to self level and you should be good to go. (Not the case in Acro mode). The same applies to flips but I found it more difficult to do. Hope that helps a little.
