Since repairs are as easy as soldering a couple motors and the flight controller has proven reliable and capable, people have developed a few nice modifications for it. Modifications such as a chassis swap with lighter and more durable materials are fairly easy, even for those without electronics skills, and yield longer flight times as well as further improved handling.
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.
