Someone suggested that it might be possible begin operating my Phantom 2 outdoors (confirming satellite communications, of course), then slowly fly into a building (through double-wide doors) and into a large space inside, and perhaps even go through another door and maintaining good control. Is this possible? I am wondering if by doing that, all the failsafe and control will be suddenly lost? For example, if my Phantom 2 is inside a building, doesn't it lose the ability to simply hover if I'm not moving the joysticks on the controller? How does all that work if no satellite? I would appreciate any advice on how this might be successfully done, or if I should avoid doing anything of the sort. Thanks!!
