Let's forget for a moment what DJI recommends. I can't pay attention to that or I'd only fly half the year. That said, I haven't had a chance to do many winter flights with my M4Pro. Well....I could have I just use my Mav3Pro much more often. A few days ago I brought my Mini 4 Pro along and flew it a bit. I'm so used to my Mavic 3 Pro flying in extreme cold that I was paying little attention until about 12min into the flight my Mini complained with a warning on the screen. I didn't mess around. I returned immediately. It wasn't "cold" by my standards, roughly -20F but I have had this "problem" with my Avata too so now I know that I can't, and won't, fly them at those temps. A day later I got some nice images and video with my Mavic 3 Pro at -27F including a 106image 3x tele panorama that PT GUI is even choking on. Anyhoo...I'll do some flights at 0F when it warms up at some point in a month or two and see if the Mini4Pro can tolerate that.
