This past weekend I was at a mall show and a local hobby store owner dropped by and asked for volunteers to fly some electrics and pass out his cards. I'll fly anyone else's planes, anytime. But the other two guys grabbed the airplanes and I ended up with a dinky helicopter. I told him I didn't know how to fly a helicopter, but he said "play around with it anyway." By the third three-minute charge I was taking off and landing on a table-top in the same spot after circuiting the 30 foot square table enclosure where our models were displayed. The heli was a e-Flite Blade mCX. This thing HAS to be the easiest helicopter there ever was to fly. A member who also flew it who does fly r/c helicpoters said it was similar to a "real" tail-rotor model, but MUCH easier overall. It would be a great indoor practice aid in any case. All the basics are there even for aircraft, though the "conversion" from fast = up, up = backward, down = forward would lead to misery if you knew only this and tried to do aircraft. I'm really impressed how crisp the yaw is. It will snap 90º or 180º and lock on the new heading solidly. Seems a lot of "dumb-thumb" has been engineered out of this model.

$130 gets you the heli, a 2.4GHz (!) transmitter, flight LiPo battery & the charger base (uses 4AA - kind of a bummer for an indoor heli).
