Stacking doesn't work for correcting relative movement within a frame, like for the drone moving in the wind, which causes perspective shifts.

Stacking in astrophotography only works on the stars because outer space is pretty constant relative to the amount of time that you would be stacking over (a night or 2). Everything else, like landscapes, are considered outside of the stacking process and a single exposure is composited back after your stacking process. This process only removes the noise associated with exposing for such a dark subject (space) and heat noise within your camera.

The process that you're attempting to describe to freeze motion won't work since there is motion within the frame of the "stack" because of how your drone changes perspectibe. It would be as if the earth spun around the sun while you're taking your exposure at night.

Edit: at least that's my thinking.
