[QUOTE="Ted Schoenfelder, post: 83514, member: 7687"] I am sure you Googled LVM, but here is a link if you haven't gotten to it yet: [URL='https://forum.dji.com/thread-142844-1-1.html']Litchi Virtual Mission[/URL] Very useful program when planning flights since you see the 3D route, with changes in altitude.
