I'm wondering why the PID parameters by default for Z control are high (about 4000 to 5000)? Is there any technical reasons for that? Which are we trying to control, the thrust, the error between refernece height and real height, or what?

The output of this PID is in PWM ratio between 0 and 65536, this is why these coefficient are so large.
