If someone is interested in:
The motors have a speed of about 20.000 min-1 when hovering, the maximum speed is about 28.000 min-1 when you pull the Tello down by hand (it tries to compensate with a higher power).
I have measured it with an optical sensor which was sticked to the cover as you can see on the photo.
