I have the Blade CX2 with the black Seahawk body on it (see photo below). It looks cool and is easy to fly indoors or outdoors (with very little wind). The CX2 has a rate gyro that holds the tail pretty well, but it will drift a little, and as the battery runs down you have to adjust the rudder trim a little to keep it from drifting. The CX3 is supposed to have a heading-hold gyro, which will not drift at all, should make it easier and more fun to fly. Not to mention the cool light kit that you can add to it, with remote on/off.

I've heard good things about the mCX, and have been trying to hold back my urge to buy one to save some $$$, but I may just have to get one afterall!
