I just flew the Blade CX at a local hobby shop... very nice! It's slow to respond to cyclic input (compared to the CP helis I've flown), but extremely stable... very easy to hover around indoors. I just hovered around a few minutes with it... didn't have much room to do much else, and I never get too brave with a heli I don't own!

I'll definitely consider getting one for indoor flying this winter...
