I've recently been told about the "Anti-gravity" setting under "Pitch Pump Booster". I can't really understand the purpose for this mode and there doesn't seem to be any info on the spirit wiki. Has anyone tried this setting? Does this help with stabilising the collective pitch or it's for something else? Thanks.

Its really designed for smaller helis to help provide 'lighter' disc loading.

I believe some like to use it in larger helis also. I have not tried it personally, so others who have could shime in?
