Thank you for your reply. @anasarrak
After that, I confirmed the spinning of the motor many time.
They are spinning in the correct.
Now, two problems occurred after loading the official parameters.
1, Second and third moter not spinning.
2, ESC can’t be calibrated with “All at once calibration”.
What should I do?
And, I tried to compare my parameters with the official parameters.
I found a difference between variable name and quantity.
Is it related to the reason why Erle-copter does not hover and two problems?
Currently, my parameters don’t hover.
I want to hover this drone.
Thank you for your cooperation.
