Tello does not start after the propeller replacement

[Tmeszi]

I lost a propeller, I replaced and now Tello does not start! I calibrated again, the engines are spinning but I do not get up! What to do? Help, help ........

Check that you have put the correct propeller. There are notches on two of the propellers. Those should go to the front (where the camera is at) of the quadcopter.

I have used a silver sharpie to indicate the two props that are different from the other two. I also marked then under the props where the silver props are needed. BTW, I also marked my spare props too,just in case
