I am having a problem with my Phantom 3 stopping video recording in flight. It did it with the card that came with it, I upgraded to a 32 gig Sandisk extreme. Problem is the same. I have reformatted the card in camera multiple times, upgraded the firmware. Re-installed the firmware. Same problem. After the latest upgrade it extended the time till it stopped recording, but also would stop recording and change to still photo mode. At first it would stop under a minute, now I have made it as far as 2 minutes but it does the same. I realize that a time or two I might have bumped the recording switch on the remote controller, but a test of the copter hovering nearby with the controller sitting on a table not being touched yielded the same result. I am considering that I might have to return it. Any observations?
