While it does not have a whole lot of features, Orientation mode is pretty useful. It ensures that your drone stays within connection range and won’t fly off on you. The LED lights are great for night flying, especially when the battery is low and you need to ground it quickly. It can do the basic flip approximately 1 meter off the ground to ensure it doesn’t collide.
Although this HD Drone can be flown safely outside, make sure to avoid too much wind whenever possible. This is a lightweight drone, and as such it is susceptible to harsher weather conditions than some of the heavier, higher end drones. For hobbyists just itching to go out on blustery days when the wind is howling, try leaving the drone at home and taking a kite out instead.
Another great feature is you can use your fingertip to chart a flight path. You do this by dragging your finger across the video image from the drone that is shown by its app on your smartphone. Then, the drone will automatically fly the flight path you have chosen. You can also teach the drone to respond to voice commands that you record with your smartphone.
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.
