IMHO, I don't think you need a new heli. I think you need a good quality lower rotor. I hope my peers don't blow me out of the water on this but, I own the Esky Lama V4. It's very much like the CX2. Many of the parts are interchangeable. Many parts on my V4 are Skytec and I'm extremely pleased with them all. IMHO, worth every penny.
Maybe someone can comment on the CX2 Skytec lower rotor (or other parts):
