I just added another tutorial to this page:

It is a video on how to add the Fat Shark or ImmersionRC First Person View feed/transmitter with the iOSD Mini to your DJI Phantom 2.  This allows your to see what the gopro is filming in real time.  Plus, the iOSD Mini shows you actual flight data from the Phantom 2.  The flight data includes the horizon line, distance from the original GPS location, speed, battery remaining on the Phantom 2, and more.
