Problem with tello, engine turns on when you turn it on

Greetings friends droneros, I come to the workshop to repair a tello, when the drone is turned on from its ignition button a motor starts to run alone, I change that engine and the problem persists I appreciate that I collaborate with that as it is the drone of my grandson thank you

Since this forum is only about drones made by DJI, you probably aren’t going to find anyone who can help. Try asking this question over in the Tello Pilots forum.

Take it back and buy a new one
