I'm not sure how the setting is on ebay units, perhaps it is preset by whoever made it? Is there a mechanical setting to adjust? As far as I know the NAZA won't change the angle at which the pitch is, it will only calibrate it to the extremes that are set in to the gimbal. Meaning you can tell the NAZA how far to pitch within the specified range of the gimbal. For my Arris gimball, I had to set the angle limits in separate software.
