This giant of a remote-control helicopter is expensive and a bit frivolous, but it’s a blast to fly. Thanks to four big rotors and an onboard CPU that automatically maintains altitude, the Parrot AR.Drone is effortlessly more stable than other RC choppers. But what really sets it apart is the control scheme. The AR.Drone creates its own Wi-Fi network, hooking up to a free iPhone/iPad app that offers touch and accelerometer control and remote feedback from two onboard cameras.
