Has anyone come across this situation? I have a Hero3 BE mounted on my Zenmuse H3-2D, which is working fine (so far at least - I've been reading about the woes of others that have had some bad luck with their gimbals). I have the latest firmware loaded for both the Phantom and the Zenmuse - 3.14 for NAZA and 1.02 for the gimbal (BTW, is anyone else as annoyed as I am that the Phantom shell has to be opened up to update the GCU? The shell is too fragile at the screw mount points to take more than a couple of openings, and I've already had several pieces of the shell broken off where the screws are supposed to hold the top part of the shell. Poor design, DJI! I've resorted to using zip ties to hold the shell together . Anyway, my problem is this: I notice that on several flights, the Hero3 shuts off for no particular reason, sometimes 30 seconds into the flight, other times 2, 3 or 4 minutes into the flight. Sometimes it happens when I'm tilting the gimbal down to vertical, other times without using any adjustment on the tilt (I use the shapeways tilt lever, which I physically limit in travel to 90 degrees from horizontal to vertical). So there's no pattern that I can discern for when it shuts off. I do not use the GoPro app to control the camera, but turn the camera on to record just before flight. I have flown it in both ATT mode and GPS mode, with all gains at default. I've flown it in calm as well as windy conditions, without any of what I would consider extreme maneuvers, and there is no pattern that I can figure out :shock: BTW, camera remained on during my last unplanned landing (oops!) in some tall grass, even though the gimbal separated from the Phantom, so I don't think it has anything to do with g-forces on the camera. I've checked that the Hero3 is being charged by the Phantom battery. I'm shooting 1080p@60fps with Protune. This is my first post after lurking for a few weeks. Thanks to all for the tips I've picked up so far.
