I have had my trusty Phantom 1 for about a year now, 100's of perfect flights. I went to have a quick flight today and noticed something different. After flying with it so many times you get to know the Phantom inside and out and this I have never noticed. It started raining so I was in a bit of a rush so I tried to pull of the batteries connector with one hand. Not advised I guess and as the XT60 connectors are a very snug fit it wouldn't pull off so I had to get my other hand and grip each connector and pull like usual. During the initial attempt to pull off the battery the Phantom rebooted back up with the 4 motor sounds. I thought that's strange, the batteries still connected. Just got home and checked the connectors and all seemed fine and secure. I plugged in a battery and it did it again, rebooted without unplugging the battery. I then applied more pressure to the wires going in to the XT60 connector and look what happened: The actual wire has severed! Couldn't believe it, this is what nightmares are made of Now, I myself may be slightly to blame for this catastrophic fault. I use Turnigy batteries and as they are slightly bigger its more of a tight fit to push the XT60 connectors back in on top of the battery. The wires are obviously bending each time and I guess the repeated bending has weakened the wire and caused this breakage. So be warned everyone!
