Hi, I have a Phantom 2 with Zenmuse H3-3D, GoPro 3. My FPV system is as below. AVL58 Transmitter and BlackPearl RC801 monitor (with own antennas) It's strange but for one whole day I have no problem with my FPV system, I see what the camera sees but after couple of hours I want to fly my bird again, sometimes no matter I do I don't have the live footage. I re-adjust the channels, make sure that my monitor and the AVL58 transmitter are in Channel 8. Then I try for sometime and somehow the live footage comes back? Any ideas why this can be like this?
