I understand your feelings, and we all need to move on at some point.
I've been very happy with my CX2, it flys, hovers and maneuvers well throughout all of my minor modifications.

It is what it is.
If I wanted a high speed, fully maneuverable, 3D heli I would have purchased a T-REX or similar.
And I may just do that in the future, possibly the Blade 400.

Maybe you should have moved on long ago, maybe not. But when the fun is gone it is time.
Good luck with whatever you decide to do.
