I was flying around a local mountain this morning and I wanted to pan nicely around the summit. Only I miscalculated my altitude and a ridge cut off my line of sight to my P3 (I was 2 miles away) and I abruptly lost signal. I had set the RTH altitude to 500 meters as the summit of the mountain is about 480 meters above were I took off.
I can't tell you how close I was to setting it to 250 meters or even lower since I wanted to avoid the annoying low battery warning on my return home since the Phantom calculates not only the distance to home, but also the time and energy to get to the RTH altitude.
Luckily I decided to keep it at 500 meters or my P3 would have kept below a ridge line (i.e. totally out of my control) and certainly crashed into the mountain.
