Default Vbar specific - trim flight and piros

Hi there, my A500 flies very well, but I can't piro on the spot. It hovers nicely, so the swash should be pretty much levelled. I did some trim flights but don't see any improvements. The trim bars in the vstabi Sw don't display much offset, another indication that the swash is levelled. What I don't see is that the bar 'time' grows. Don't know how to achieve this. I hovered hands off for 5 seconds or so.
Now, I also tried to rotate the swash in the Sw. I was hovering and then yawed 90deg right. The heli started ff to the right. Then I did rotate the swash ccw and the situation improved. However, I started with 270 deg (first value in the Sw) and went up to 295. The piros are almost fine then, and minimal ff after rotation. This seems to be a lot. When I did an elevator flip with those values it also looked like the tail changes position during rotation...
Vbar experts, any thoughts? Thank you and best regards, Stefan

No ideas?

Meanwhile I managed to get a green bar "time" after trim flight. However, I still cannot piro on a dime...

I don't know anything about the vbar setup but reckon users in this forum do: http://www.helifreak.com/forumdisplay.php?f=97

Maybe there's a similar part in the vbar setup as the beastx where the swash tilts and then you have to hold the rotor and turn the heli around it's axis. The swash then should remain in the same position as the heli rotates. If that's not setup correctly it won't correct properly in when the heli pyro's.

Thanks for your help. I've copied my question already to the v bar section and the folks over there came already up with some ideas...
