What does gimbal configuration 1-3 do?

Completely undocumented and I can see no difference no matter what values I enter.

In the downloaded upgrade file  and unzipped their is a information file generated that lists supposably upgrade points

you can adjust the speed of gimbal movements. for my self i made slow, medium and fast

I dont see any effect for gimbal speed with the gimbal advanced configuration settings. When I turn the plane with my hand it always does the same in the same speed no matter set to 0 or 100

Good Point, would be interesting if somebody can confirm that. I was wondering also about these settings.
Are there any dual operator out there?
