I was flying my Phantom 3 the other day and everything went smoothly. I did the normal procedure after flying and put it back in its case. I got to my next location and took it out to fly and it said gimbal disconnected. I have never wrecked it. It has a signal. It turns on, the camera does its thing for 3 seconds and then dies and goes limp facing down. I just recently updated it , but it didn't do this the first time i flew after updating. What do you guys suggest i do?
