I'm mentioned in other threads that I have flown at -20F and colder without problems with my DJI FPV and Mavic 3. Just yesterday I was flying my Avata and got a message, something along the lines of "Battery Temperature too Cold" or something like that. I returned back to my launch spot and flew around very close to launch but had no actual issue. It was -10F and strong winds. The winds were strong enough that at one point I could not make any forward progress at all until I lowered my altitude from 250ft to 20 feet.
