Something new started today. Conditions were clear sky, mild winds, 42º. After 7 or so minutes, the camera's view dropped looking down at the ground. I have the standard X3 camera. I could not use the left roller to move the camera up nor down. I clicked the C1 button, and it would not move left nor right. I brought the bird down, turned it off, turned off the transmitter, restarted both and the camera went through the normal startup, and was fine. I put it back in the air, and again after 7 to 10 minutes the same thing happened. This has never happened before. Any ideas as to what the problem may be?
