Meet the EDrone Black Knight Drone: a WiFi quadcopter that folds down to a 7″ cube, so you can take it anywhere. It has convenient features such as headless mode, one-button return, WiFi FPV transmission, and G-sensor control. You can also perform 3D flips with this.
The cube drone comes with a convenient controller but you can also interact with it from your smartphone. The battery lasts for about 6 minutes.
