Do remember that drones are illegal in federally designated wilderness areas, where many of us, especially in the western US, do most of our backpacking. In other words, your gadget cannot be used in those areas where there would be the most need for it due to isolation and rough terrain.
Plus, the general opinions expressed on hiking/backpacking forums here in the Pacific Northwest is an extreme dislike of drones, including threats to shoot them down! (Not by me, although I'd be sorely tempted!)
