Hi Pan,
Normally, the ESC starting power for outrunner can either be low or medium; the correct setting has a lot to do with the motor you use, since they all have different magnetic strength, so use the one that can easily get your motor turning without any screeching sound, and the best way to find out is give them a try.
As far as the PWM frequencies concern, again, depends on the motor you are using, you need to adjust it accordingly. Generally, you will gain more power when using higher frequency setting, and in your example, the 16KHz. From the testing I have done using my motor/ESC combination, the power gained from higher PWM frequency isn’t very significant, and since the power output from my setup is already more than I need to fly the sequence, I chose lower frequency (8KHz) to conserve battery capacity.
Finally, although I am not familiar with your ESC, but based on your description, that you have to move the throttle stick from idle position to full throttle position in order to calibrate, this appears to be auto calibration, and not fixed endpoint setup. The fixed endpoint setup should not require user to move the throttle stick at all.
Hope this helps.
