Shouldn't a gyroscope compensate or at least allow getting flat level? I think maybe they didn't use it because they didn't have accurate gyroscopes we have now.

For clear shot, would tiny drones that go up work? How high do we need to get a clear shot?

Go outside, do you see a flat level horizon?

You could use the accelerometer to get a good idea of "down" but not enough resolution for navigation.
