I bought this specifically to learn to fly collective pitch helis and am very satisfied with it. Graphics and physics are excellent. The reason it doesn't get five stars is that it has limited plane models. I would suggest that you review the videos on YT from AccuRC on how to set the sim up. Jonas from AccuRC has excellent tips on how to slow down the simulation to give a beginner a chance to develop a feel for flying a heli.
So, yeah, if you want a heli sim, this is a great choice. If you are looking primarily for planes, their are other choices. But the price makes this one worth a look, in any case.
