I was able to fly my Mavic Air at 16 degrees Fahrenheit for around 4 - 5 minutes before I brought it back.   That was at an elevation of 12,000 feet near Loveland Pass.   I warmed up the drone and batteries with my car heater before the flight.  Seemed to do ok.  I did that 3 different times within an hour getting shots of Arapahoe Basin, Loveland Pass and Loveland Ski Area near Eisenhower / Johnson tunnels.  If you are going to do it, I would do short flights after warming it up.  Maybe bring a big net to catch it
