If you are new to rc flying things, please get some help from someone who isn't new! The CP heli is a LOT of fun but it takes a bit of skill to get it off the ground without crashing and tearing things up. I would hate to see anyone get turned off to the hobby because they crashed at first! Here is some advice:
Set it up perfectly mechanically first.
Get an experienced heli pilot to fly it first and tell you that it is OK to fly.
(They come from the factory pre-flown and set up sort of OK, but it sounds like yours may have been messed with and you need to know that it flys before you try it yourself)
Fly it indoors in a _big_ room first. It really can't take a lot of wind if you don't yet have a lot of hover practice. No carpet!
Get an extra set of blades, but you can fix the tip dings dings for quite a lot of life if your crashes aren't too bad.
You _must_ train yourself to get the throttle off completely __before_ the blades hit something or you'll blow the 4-in-one--probably what happened to yours.
How do I know all this? I got my blade CPPro about a month ago...
