Run drone reconnaissance on your own neighborhood with the Spy Hawk (£250; roughly $400). This unique RC glider sports a built-in 5 megapixel camera that streams a live video feed back to the 3.5" LCD on the controller, which also holds an SD card for recording your flights. Of course, all of that isn't much good if you can't keep the thing in the air, which is where the intelligent autopilot comes in — fly it up to the required height, switch it one, and a built-in gyroscope will work to keep it level, even in gusty winds. Or you could just tie your iPhone to a balloon and pray — totally up to you.
