The advice I haven't seen given here yet, which is key to improving your flying skill - When you fly, don't just throw the sticks around and see what happens and then try to recover - thats what we call "flying behind the plane". Instead, "get in front of the plane". In other words, fly with a purpose. Work on one maneuver at a time. If you want to learn to enter and recover from spins, just do that for an entire flight. Slow rolls - same thing. Snaps? Same thing. Repetition is the key to muscle memory. Think about when you're going to start the maneuver, what stick movements you'll use to enter, and what movements you'll use to exit. As you practice these skills, it will become more natural. Then you'll be flying the plane, not just keeping it from crashing.

You mentioned 1.8 cm as your throw, but didn't really tell us which Edge 540 you're flying. You did say it has a .61 on the nose. Those throws will probably be a little tame, which may encourage you to use larger stick movements than you should be using. I generally look for 15-20 degrees on low rates, with 30 or more for high rates. Then I use some exponential to calm it down near the center of the stick.

I have the Fliton Edge 540 Freestyle with a 91 four stroke, and its a great flyer. Very predictable. If you can fly the snot out of the Stik, you shouldn't have any problems with the Edge. My recommendation would be to fly the covering off the Stik before moving on the the Edge.
