No problem running my Autel Xstar Premium in the cold weather. Biggest problem is my fingers freezing up on the controller. Battery life did seem a bit shorter when it was really cold but everything worked ok. I made several videos in the winter because the snow scenery is pretty impressive. I shot this one last January. The drone was flying itself once I set the limits. 
I recorded a second video about a month ago when it was between 5 and 10 above F.  https://youtu.be/TnAYd7_7Uos
