Just completed the firmware update which was mostly successful although not very positive. Next time I will definitely do the drone first and controller last. Oops. Anyway after the update process the camera started to get rather hot and the little fan on the back of the camera is not running. Obviously the drone is sitting in my room with the blades off no motors running etc. Should the wee fan run when the camera is hot or does it only run when the drone is flying? Bit worried that I have a defective camera and its only a couple of weeks old.
