Hi, maybe it is just me and my anxiety when flying our bird so high but it sure seems like it takes a long time for the thing to start coming down after I pull down the gas when using AH. I was on a shoot the other day and I swear it took about 60 seconds before I heard the Vario sound. By then I had lowered the gas so much it started approaching terminal velocity. C8, MK2.1, QC-3328, FF 3-Axis w/ radians, Sony 760v. I should probably just turn off AH and descend manually but I keep forgetting to try it.
