I've been working on a project in snow country - and the weather has been pretty cold - between 12-18 degrees F. I needed to get some aerial footage so decided to try to fly in these temps. Good news - have done 4 flights with temps at ground level of 14-18 degrees with no problems. The only issue is that the battery does drain faster but that is manageable. I have a Vision + with the QR mod and a GoPro4. It all is working well - the FPV works fine as do the flight mechanics. The only problem piloting the drone were my numb fingers. This may help others hoping to fly in the winter - the temp ratings that DJI has are clearly an rough estimate. MT.
