Haven't found a great resource or buyer's guide for action cams. Everyone's first reaction is the GoPro, but I am getting the sense that there are better options out there at a lesser cost (gimbal situation aside). What are the WiFi ranges on these cams? I can never find exact specs in terms of distance. Currently, I fly with the FC40 stock cam, and I haven't had any issues with being able to view the live feed on my smart phone. Are most action cams going to have the same distance ability as the FC40 cam? Thx!
