Sad to report the loss of my phantom. Had it out on a sunny, windless morning. Started it up when it had satellite lock (8) and flew around. Tested Home lock and it worked as usual. I went flying at 200 feet and within 500 feet of my location, line of sight. Had 45% battery left, and was hovering and taking photos. The last time I looked, it had 10 GPS satellites. Suddenly, lost connection in the app on my iPhone 6. Started to bring the Phantom home by switching to "IOC Home lock", right stick back. But the Phantom started moving away. I switched to RTH, it kept moving in the same direction; and then I watched the Phantom continue away from me until I lost it in the tree line before I could try and regain control with ATTI. Somehow, it must have reset its GPS home location, or lost GPS all together. GONE. I searched for an hour in the direction it went, but it had over 10 minutes of battery remaining. Wouldn't you know I had just removed my Flytrex Live to have it repaired, it had a bad cable attachment, so I was flying without a tracker. Dumb. I just hope and pray it didn't hurt anyone. I suppose this is a good excuse to by a P3, but my heart just isn't in it right now.
