Nearly a year ago I was given an Autel X-Star Premium for repair and cleaning. The owner said the aircraft returned to home mid-flight and landed by itself, during which he had no control over the aircraft. After this he could not get the controller to connect to the aircraft. Rebinding the controller to the aircraft seems to have solved the problem. Perhaps the aircraft became unbound mid-flight?
The quad had also been crashed on a beach earlier that day and was full of sand. The motors and gimbal were sticking at some angles, as there was sand lodged inside them. Rotating the motors while blowing air into the gaps was all they needed.
I had the aircraft partially disassembled to get the sand out and decided to take some photos to document the internals purely out of interest. Some time later I realized there were no teardowns of the X-Star online, so I put together my own.
