Hi all, I bought the Phantom 2 Vision + last week. I did some great flights during last weekend and everything went very well. Today, I went out to fly again. At first, I could not get any GSP satellites (GPS icon was grey). I changed location and there I had 8 satellites. I took off and after 10 seconds, the number 8 disappeared, the GPS icon turned grey, I had huge difficulties controlling the Phantom and crashed. I changed to another location, a place were I flew 40 minutes last week without any issue. Same thing happened. I changed to a total different location. I had 10 satellites. After being 3 minutes in the air, suddenly the GPS icon turned grey again and the Phantom became very difficult to control again. Is there anybody who knows what can be the reason for this and how I can solve it ? Thanks very much in advance !!!
