The word “drone” has taken on a few different meanings over the years. Some people think of a drone as a bee, others might think of those predator drones that the military uses. The drones that most people talk about today are simply radio controlled aircraft that have some level of autonomous features. A drone can be a plane, a helicopter, a quadcopter, or any combination in-between. Most of the drones sold today are quadcopters. They have 4 rotors and a flight controller that is used to stabilize the lift from the each propeller.
Generally speaking, drones that cost less than $100 bucks aren’t worth your time. They’re flimsy, they lack advanced features, and they’re almost always squirrely as hell in the air. But Tello is different. Despite the fact that it retails for only $99, it boasts a boatload of high-end features and functionality. Under the hood you’ll find a 14-core Intel vision processing chip, flight stabilization tech from DJI, a 5 megapixel camera capable of shooting 720p HD video, and a battery that gets you 13 minutes of flight time.
