You will be able get the CX3 as both a complete RTF (with radio) or a BNF (does not include a radio, but does include everything else so it can be bound to any DSM2 capable radio). At least that's what HH says.

I apologize if I came off pushy on the FP/Sim. I wasn't meaning to be. I was just trying to give the most information possible for you to make an informed decision. If the CX3 is your choice, I'm sure it will be an excellent helicopter for you and you will be happy with it. It looks to be substantially similar to the current CX2, so you should be able to get plenty of assistance on here if need be.

Enjoy whatever you choose and happy flying.
