Just having a little fun...this thing is indestructible....I have broken a prop guard and a few props, but they are cheap and nothing else gets broken...I hope I didn't put the whammy on it now
Tello is a fun little drone. For even more fun try out the TelloFpv app which replaces the stock app. You can do the things the stock app can do plus Circle POI, Lock POI, Dronie, Boomerang, Orbit, and 360 Pano and more. You can even fly fpv if you have some box goggles. @volate!lo even has another app called TelloMe which allows Tello to track you. His apps add functionality to Tello that the more expensive DJI drones have.
If you want to try basic Tello programming, you could try Droneblocks (free).
