You don’t have to change the batteries in the controller. Great drone, good on wins and great footage. Music, invest a great deal in learning how to use this drone, but overall it’s easy to use here are some sunset picks. I found the dynamic range to be lackluster in these Music. I do like that fact that the drone is small, quiet and unobtrusive update. As of december 22nd 2019, i am going to add a sunset photo as an example of what is possible, with the mavic mini judge. For yourself update, i am going to add two night shots. They are each about one second exposure. I got the warning about high wind. It was at about 360 feet for the town and maybe 60 feet for the street shot Music.
