the Walkera #4 is the same bird as the Falcon 40. Exactly same.

I disagree with MRASMM (only on this one little point) that another good Walkera choice is the 5#5 (a much better bird than the 5#6, i know, have both)

I see that you are looking at both COAX and single rotor helis. There is a mixed bag of feelings here on which one is a good first step. I'm of the mindset that a coax is a great first step past the toy stage.

Also, what is your flying area? Winter is coming so you may want to find something that you can fly indoors. Even though mastering hovering is quite exciting, it gets old in the basement after you have good mastery of it. Maybe something smaller that can be flown indoors better.

If you have decided on the bigger helis, then my vote out of the 3 you mentioned is the BeltCP. ITs quite big and too big for a beginner to fly indoors. Unless you wallet and repair skills (for heli and objects in house) is unlimited.

Some things to think about.
