I don't mean to step on anyones toes with my post

. It is, as you said, just my humble opinion, as are all my posts. The Blade CX i'm sure is alot of fun to fly, but mechanically, it is very limited, that's just a simple fact.
I've said it in the past, and i'll repeat it here now. If learning to fly bigger nitro helicopters is your goal, the Blade CX (or any counter-rotational 2 bladed helicopter) makes a great trainer as the flight stability is very similar. If your goal is to go to something like the Blade CP, T-rex, or equivelent micro electric helicopter, you'll be in for a BIG surprise transitioning from the CX. I'm not saying it's not possible, since many people do it, but you'll find the going harder.
