There is an altitude hold function that allows you to take aerial shots by releasing the throttle.  Once the throttle is released, the drone hovers in place and take the shot. As a beginner, the headless mode will help you to understand the capabilities of the drone better. Once you’ve gotten conversant with the features, you can do aerial tricks and flips with the drone.
Oh, and let’s not forget about the camera. In addition to a 12-megapixel camera that shoots video in 1080p at 30 frames per second, the Spark also sports a two-axis gimbal. This lets it mechanically stabilize the camera and cancel out any jarring, shaky movements — resulting in smoother, better-looking footage. This also gives it a leg up on the competition; most selfie drones only feature single-axis mechanical stabilization.
With headless mode, you don’t need to worry which way the drone is facing because your controller is the basis for the drone’s orientation. In other words, whichever way the controller is pointing is the way the drone is pointing. This will help you master all aspects of drone flight, and as such it is one of the top features that beginners should consider.
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.
