Here is a patch for the PC Setup Software, to make the parameters "Lightness" also called "Anti Gravity" and "Tail Wag Suppression" accessible from the PC side. Please replace the file config_62.sec with this one (file is inside zip archive). On Windows PC, it is inside the "C:\Program Files (x86)\VBarControl" folder. It also works on MACs, right-click the App as if you would place a keys.sto-file there, Show Package Contents, move the file to the same location (link to folder). The parameters can be found in the expert settings of main rotor and tail rotor.
Lightness = Anti Gravity, Wag Sup = Tail Wag Suppression
