Hello, I have lost sight of my phantom on 2 different occasions. Luckily, it came back both times after I turned off the remote control. I thought I had read that when the phantom would lose the signal from the remote, that it would drop down to 50-60 feet and then fly home. Both times, the phantom stayed at its current altitude until it got to the home location then dropped down, which is probably the only reason it made it since I fly around alot of tree lines. So is it officially supposed to drop to 50 feet or will it stay at its current altitude?
