Remote control helicopters are awesome (check out Alan Szabo for reasons why), but not new. Quad-copters, controlled via an iPhone are new and awesome.

The AR Drone has four fans, providing a high level of stability, and controllability. It's able to hover in place, and is maneuvers well enough that you can play augmented reality games using the copter as one of the participants in the game, fighting computer generated opponents. Plus it has cameras. One at the front, and one towards the back facing down. Video can be streamed real-time back to the controlling phone.
