Ordered some of these guys and wanted to do a flight time comparison between a naked Phantom and my Phantom loaded down with a ZenMuse and FPV. Both flights were identical. Very conservative. Both helis have stock props. Naked Phantom: 12:45 ZenMuse, Hero3, DJI 5.8 with small dronefly battery: 5:35 Seems to me that is a massive dump in time. Would it help to have my FPV direct wired into the main battery to save the weight of the smaller FPV battery or would the extra drain on the main battery be a wash..
