Drones these days are easier than ever to pilot, but the science behind the technology often goes overlooked. That is why Rhett Allain, a Physics Professor from Southeastern Louisiana University, created a video explaining how drones fly.
How drones fly: Hover
Professor Allain used a DJI Mavic as a model to explain a drone’s flight. When a quadcopter hovers, there are two opposite rotors that spin clockwise, while the other rotors spin counterclockwise. To keep the drone stable, all the rotors are powered equally.
