What pwm rate / frequency should be set for this motor?

Usually our motors can be run on all pwm rates / frequencies. A too high frequency will usually result in the esc getting warm/hot, so the best practice is to check your esc after flight and to drop your pwm rate in case you notice any heat developing.
