I am trying to spec out my FPV setup. I have the Phantom v1.1.1 Hero3 + Black Zenmuse H3-2D Upgrade board To avoid added weight I am not getting the PMU V2. If I setup the FPV like the picture can I still integrate IOSD? http://image.helipal.com/helipal-dji-avl58-fpv-connection.jpg Also is there any downside to pulling video via the USB port on the GoPro? Thanks!
