Headless mode is another prerequisite feature for your dream device. Also referred to as cheater mode, the headless mode allows you to direct the drone to see any direction it goes as forward. Thus, you do not have to bother about flipping it around and bringing it back to your location at the end of a flight. Once the headless mode has been activated, simply push the joystick in the corresponding direction you want your device to move towards.
If you are a beginner just learning to fly with these cheaper drones, take your time to learn the controls by flying in a safe area that is a wide open space, with no wind, and no obstacles. At first, fly low to the ground until you can maneuver your drone correctly. Practice flying on a single battery charge and then let the drone cool down for ten minutes before flying more. 
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.
