I'm a newb, starting with the G2 simulator, and currently building a Raptor 50 V2. The sim will give you some serious respect for an RC heli! When you see how difficult it is just to hover, you'll want to put many, many hours into the sim before risking your expensive heli hovering for real! I decided that I needed to at least be able to hover, tail-in, on the sim before I shelled out $$$$ to buy my heli and radio gear. My goal, now, is to be able to hover well in just about any other position (nose-in, left/right side, and at angles) in the sim before trying to hover for real with my heli. I figure, even if I'm just trying to do tail-in hover and it swings around, I want to be confident that I can still control it.
