– 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.

While hovering, it is exactly how you described. But when going forward, the rear rotors speed up and the whole drone pitches forward a bit. Usually the drone has some sensors to measure the angle and holds it automatically. Because it is no longer level, the drone now flies forward and downward. The downward motion can be countered by increasing the rpm on all 4 motors simultaneously
