I added "Flight Plan" (an in-app purchase) to Bebop FreeFlight and tried out a plan I cobbled together this morning. The first plan was aggressive, so I saved it and made a simpler one, flying around the field between the ranger station and the parking lot. I used one battery obtaining a GPS signal, but then Flight Plan worked like a dream.
I updated the Bebop firmware, and FreeFlight, yesterday. Not sure why all the Bebop activity now, maybe because it's 20 degrees and Xmas is around the corner.
