After setting up the drone and calibrating it using the QGroundControl application, I took the drone into a large room to have the first flight. I first flew it using the controller and the drone behaved correctly. After that I used the QGroundControl application to connect to the drone and used the 'Takeoff' option (as shown in the image below). The drone took off, then it started leaning back and flying diagonally, then it just shoot off and crashed into the ceiling. Could you give me any hints as of what might have caused the drone to suddenly fly out into the ceiling?
