RE: WHAT HELI I SHOULD BUY??
If you don't want to waste a lot of money, stay away from those cheap garbage helis. Get yourself a sim and start practicing. Then watch ebay and RCU for a good used Raptor 50 or 60. I got my first raptor 60 new with engine a few years ago for $300. If you watch hard, you can find a deal. Haven't seen one that good since, but if you want to spend less in the long run, get a good heli. Raptors are good, parts are cheaper and they will do anything.
The problem with a heli is you will break it and wear out parts. They are expensive, but a lot of fun. Don't start with junk. You will just spend a bunch of money and not get much flying time out of them. There are lots of posts from people who have bought them and are ticked that they are so bad. Why go there!
Good luck. Hope you get the one you want. They rock!
