I was a bit confused at first by this... a quadcopter with no transmitter? But then I saw the potential! If you've got a smartphone or tablet, you can control this thing. If you have an Nvidia SHIELD, you can control this. And, of course, if you have the CX-31, you can use its controller as well!
Note: You can't control this over wifi without having the camera attached, so make sure you've got a CX-31 or CX-30 transmitter if you plan to use this without the camera.
