RE: Which Heli?
I would say to get a ARF also. You get the fun of putting it together, as well as a little frustration. When you pick and choose the parts, you can get better parts then what is usually included in a package deal. Not that the RTF helicopters are bad, you can just put together a better setup out of pieces.
Of what you have listed I would say a Belt CP or Falcon. I have the HBK2 and have a lot of fun with it. It is a good all around helicopter and parts are all over the place. If you are looking at the Belt CP, check out jaghobbies dot com for any Esky stuff.
