Hobby King Driver ESC controller PWM 8/12/16 KHz

Hi,
I saw this ESC controller

than can manage PWM at 8/12/16 KHz.

I have an Arduino mega 2560 and I need drive four of this devices attached to four motors.

I saw Servo library but that library does not permit to me to specify PWM frequency. Is PWM frequency auto-calibrating?

I saw this code

http://www.arduino.cc/playground/Code/PwmFrequency

but I do not understand if can I Servo library after that I changed PWM frequency.

I would like use 8KHz PWM frequency.

Moreover, I have to move forward and backward the engine. The stop position of the engine has a 50% duty-cycle?

Thanks in advance
Marco

The ad says "**Programable with Turnigy programming Box and Turnigy USB Linker, see related items below. We suggest customers to not program the esc with their Tx." I think that means you can program the EXC for those PWM rates and the output PWM rate has nothing to do with the input pulse rate.

That's my take also, that the pwm programming feature is about the ESC to motor interface, not the control pulses from an arduino controller to the esc, which would remain as a servo compatible 1-2 millesec pulse.

thanks... mainly about the sentence "which would remain as a servo compatible 1-2 millesec pulse" that is illuminating for me. Thanks a lot again.
