While out flying often times the FC40 camera will be a solid red when I land which I assumed was because of the cold or something. Today when trying to charge it its staying a solid red instead of the normal red flashing light so I'm not sure if it's charging or not. I've power cycled it a few times trying to get it to charge like normal but no luck as of yet... It does flash initially when plugged into the usb, but then the solid red again. Also when I turn it on it is still working, so no problems there, but the solid red isn't even an option in the manual. Any ideas as to what could be going on?
