I climbed Mexico’s highest mountain just to fly my mavic at 5,680 meters above sea level, I just had to keep the batteries warm during the climb. It acted out a little bit, it felt odd, when I hit the throttle down it went down faster than it usually does, I sent it far (about a mile) and a beeping started coming out of my remote, the proximity sensors started acting out but there was nothing on its way (there couldn’t have been anything on its way, we were at the highest point in the country) the weather helped, it wast too cold and there was almost no wind blowing (conditions that I have never encountered there).
