– How can a drone fly forwards.

Question

How can a drone with 4 propellers (as in the photo) fly forwards or backwards. I think the propellers are all on the same level. There is then no propelling movement.

Answer 1

Two blades spin faster than the others causing it to tilt. This gives directional thrust. This is the same as a conventional helicopter except it achieves tilt by literally tilting its prop.
