Active track should work if the drone is slightly behind you, or couldn't you just have enough distance between you and the drone to have in front of you in view? You could also crop so that it would appear whatever was in front of you to be the focus point.
100 off of select dji drones. I went for the mavic air, but taxes killed it for me buying a new one. I decided on a used one with 6 batteries for less than the fly more package that would have cost more.
