For me, when I started into Heli's the CX helped me learn flight orientation, nose in hovering, etc. I've owned 3 different CX's in the last couple of years, and none of them had any issues with the 3 in 1.
I think the CX is a great learning tool for moving up to conventional heli's, and I think a lot of guys out on the other boards (rcgroups, rcuniverse, etc) would likely agree. You can fly it indoors without worrying about destroying your house, and parts are very cheap when you crash, which will happen.
No offense intended here, but my opinion is that telling someone to jump right into a collective pitch heli like a Blade CP or T-Rex with no experience on a simulator, or at least some time flying a counter rotating heli like a CX to gain some confidence that you can control a heli, is a crash course in heading for a crash course.
There isn't anything that much worse that setting your brand new $200-$300 heli on the ground, spooling it up, lifing off, crashing hard 5 seconds later, and having to spend $50 just to get it "flying" again.
