I've been following this board for about a week which has helped tremendously in my research. I've decided on a Phantom 2 with gimbal as I already own a GoPro. So far I've learned a lot about the various options and add-ons. But I haven't been able to find an answer to this question anywhere. With a Pantom 2, stock controller and GoPro, how to you control the drone if it leaves your line of site, like behind a building? Does the wi-fi enabled GoPro stream the video to an app on your phone? If so, doesn't that limit the distance and trump RC? Is buying a FPV rig the only option? I know this is a probably a fundamental topic to you guys but I"m really confused.
