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
