A lot of us have played with those tiny remote controlled helicopters, but now you can control one with your iPhone. The iHelicopter comes with a special transmitter that plugs into the dock connector of an iPhone, iPad or iPod touch. The iHelicopter app turns your device into the remote control. The toy also comes with 2 spare rotor blades and a spare tail propeller, because you know you're going to crash it more than once.
