There’s more than just physics keeping these small wonders aloft When things look easy, they’re typically anything but. From Ted Williams’ swing to Raymond Carver’s prose to Jennifer Lawrence’s acting, this has been demonstrated time and time again. You might think it’s a leap to include drones with these effortless artists, but hold your judgement until after you watch an unmanned aircraft dance gracefully across the sky. Because while these machines may look like little more than propellers and plastic, these aerial acrobats actually pack a lot of tech into their lightweight frames. In order to describe how drones work, you have to first distinguish them from their predecessors: remote control helicopters.

This detail is key when you analyze one obvious differences between model aeronautics and drones: smart copters have multiple rotors. While RC copters also can have multiple propellors, hobbyist drones (not the ones flown government or the military) need them in order to achieve the level of control necessary for the unmanned aerial vehicle to be self-reliant. “When you have multiple rotors, you get a lot of really interesting benefits,” says Perry. For instance, having more than one propeller gives drones more fail-safes.

For instance, if one of the motors fails, the aircraft can still stay aloft with the remaining motors working in concert to compensate. In addition, the more rotors that you have, the more lift an aircraft will generate, allowing it to carry a heavier payload, something that comes in handy when you’re attaching a camera to a drone. And finally, having more rotors lets designers shrink the size of the blades, making them more manageable and even safer to use. But it takes a power source to get these propellors spinning.

Drones typically come with a removable battery that provides around 12 minutes of flight time. Many drone makers sell extra batteries, and you can even upgrade them to get up to 25 minutes of flight. But more power means more weight, which is why these machines get such little airtime. Everyone would love to have a drone that flies for hours on end, but the battery powerful enough to do that would act like an anchor, tying it to the ground.
