I would never recommend actually learning on a CP heli. I would start out with a quad or a CX heli. You're best way to learn is to get a simulator like Real Flight. The one thing you got going for you is the bigger the heli the more stable it is. I did a bit of learning on a 450 and I wish I hadn't. I had to rebuild the head on it almost every time I flew it. And CopperCanyon is right, even the little ones can be dangerous. The 450 can put someone in a hospital real quick so fly it alone in a large area. You're gonna wanna stock up on head parts. Mainshaft, grips, links, pretty much everything but the swash. And another real common thing that breaks when learning is tail pieces. You'll get a lot of tail strikes when trying to land. Is it a belt drive heli or torque tube? Belt drive helis are slightly easier to fly cause the tail isn't as responsive as a torque tube is. I know a busted a few tail booms and tail gears on my Blade 450 when I had it.
