Went to fly yesterday. I fly over new neighbors home site every day to take pictures of daily progress on the building of their new home. I noticed a random beep coming from my RC. Couldn't see what was causing it. Took off waited for "Home point has been updated" checked all the usual indicators all looks good. Go up to 40 feet check again still beeping randomly. Go up to 100 feet still beeping, hover about a minute still beeping but everything looks good. Fly to neighbor’s home site about 1500 feet no problems. Ok, go to take first picture and with each beep the shutter speed is changing by itself. First up then down. A little fighting to get exposure correct and fly home. Turn everything off and back on and it is no longer beeping and changing shutter speed. Anyone else have this happen or anyone know why it was doing this?
