Has anyone figured out what the slot is for on the camera body? It looks like there should be some bracket that connects to it but I haven't found any information on it. Also, anyone using the FC40 camera in combo with a gopro? One for FPV and other on a gimbal for recording? I'm thinking about mounting it to the battery door via velcro (would like to make use of that slot on camera if i can figure out what's it for).
Thanks
