I was out in the country flying this morning. It was +2° F and there was ground fog. This particular flight only reached an altitude of about 75 feet and lasted 3 or 4 minutes. When the drone landed, I noticed that there were ice crystals on the body and props. I didn't sense any change in behavior as I was landing it though because I'm new to all of this, I'm not sure what a difference in handling would look and feel like. Here's the video clip I filmed as I was taking off (speed doubled). For the rest of the morning, every time I flew, I needed to de-ice. Has anyone else seen this?
