My Q500 4K began failing to take photos this summer and I thought it was due to heat, but the problem has since gotten worse even though the temperatures are now mild. It was as if there was a loose connection, so I removed and re-secured the ends of the cable from the Q500 to the camera gimble. Then I replaced its micro-SD card. I learned that if the Q500 was sitting on the ground, it would reliably record photos or videos, but if I picked the Q500 up and carried it about, it would fail to access the camera. Are there some other places where I should look for loose connections?
