I bought the Skeleton Housing for Hero 3, to use as a FPV camera for drone flights. With the usual mounts GoPro depends relatively defenseless under the drone, the Skeleton Housing change this circumstance. Furthermore, the camera is also more stable fixed, since the mounting possibility of my Drone (DJI Phantom) is relatively delicate and you have between terminals something so that the camera still.
The WiFi switch is easily accessible in order to make camera settings using smartphone can, then you can connect a FPV-connection cable. In this case, the protective cover has to be removed anyway, the SD card can also be removed easily, without having to remove the camera from the UAV. The protection factor for the camera makes the extra weight while flying more than compensated.
