My TELLO came assembled. I downloaded the app. Connected to WiFi. Slide the turn on button. It spins for 2 seconds then stops. I read a thread about the propellers but it came assembled. I have no clue of what to do? Any suggestions?
Take off the propellers and prop guards. Two propellers have little marks on them and you will see marks on two motors where the guards came off. So the ones with the marks must fit on the motors with marks and unmarked at the motors without marks. The tello will not take off when it spins motors and the imu senses something wrong. It can also be a good idea to do the imu calibration first before you do the props. Just follow the instructions in the app
