Alot of people wouldn't be flying single axial heli's today if it weren't for the cx-2. Most would get frustrated by not just the tough learning curve; but the parts and complexity.

The CX-2 will introduce You to R/C helis without Marrying it; teaches You the basics, and parts replacements, adjustments, etc.
parts are READILY available, and it upgradeable. It is ready to fly with the Spektrum TX.

Alot of people have single rotors, but still fly the heck out of the CX-2 as it is a great indoor helicopter. No waste of Money, if You enjoy it.

I know I would have never, personally, started out with the single rotor.
