Settings for MOT_PWM_MAX and MOT_PWM_MIN

The Tuning Process Instructions in the docs say to check the ESC manual for “fixed range” or 2000us (MAX) 1000us(MIN).

The settings in Mission Planner’s initial parameters for my copter (Hexsoon TD-650) is “0” for both.

The parameter doc say when set to “0”, the firmware will use the values of RC3_MIN and RC3_MAX - which in my case appear to be the low and high value for the throttle channel in the radio calibration.

Is there any downside to letting MOT_PWM_MAX and MIN stay set to “0” and allowing the firmware to use the values from RC3_MIN and MAX?

The ESC manuals that came with them don’t have anything useful for setting these values.
