I have created a tutorial on this interesting method of combining multiple pictures taken with same settings (as opposed to HDR).
It will help you:
increase the detail
eliminate the digital noise
and increase the usable dynamic range of your camera.
I believe this could help you take your drone photography to the next level.
Once you stack you'll never look back ;)
