I've had the drone (Phantom 3 Standard) since November 2016, and it worked amazing until the other day. I took it out for a flight and the signal was weak 60 meters up and 30 meters out. I went to 50 meters out and the signal was lost and the drone went into return home mode. I could go easily 200+ meters before with no issues. I have not done the most recent firmware update so I do not think that is the issue as it worked before when I did not update it. I have re synced the controller and the drone, I am knowledgeable about the antenna for optimal performance, and it is an open clear area. If i rotate the drone it seems to get the weak signal when it faces a certain way if that help anyone with why it may not be performing as good as it used to. I'm looking for some help everyone. Thanks!
