Some days nothing goes right. My Smart Controller said the compass needed to be calibrated so I refreshed my memory about holding it horizontally and turning around then do the same holding it vertically. So I went outside and holding it horizontally, I turned around once and nothing happened. I did it again, still nothing. I tried it vertically and still nothing. As I was standing there wondering what was wrong, it suddenly occurred to me that the drone was still inside on the table and I was going around with the controller. I went and got drone and a minute later the compass was calibrated and I had remembered some words that I had forgotten and said some of them. ........Don't break anything laughing...........
