RE: Cx 2 as first heli?
A CX2 is a nice heli depending on what you want and what your end goals will be. The CX2 is VERY easy to fly after the initial learning curve....it almost hovers by itself. A CP is a completely different beast!
If you want a fun, easy to fly heli that you can fly in your house without much learning, the CX2 is perfect. If you want more of a challenge and want to eventually get into more faster flight and aerobatics, then get a CP.
Good luck,
