movement of artifical horizon

[edward7048]

I am getting some movement of the artificial horizon up and down in my
sv 1000t, sent a video to dynon and they said that it was due to vibration,
I have van's beef up installed in the adahrs area and my prop blades are
with in .1 deg. of each other. has anyone else had this problem?

It has been seen but I would say it is rare on 12's that have the brace installed.
If your blade pitch is close, start looking at other things that could induce airframe vibration. ( confirm a good carb synch, have a dynamic prop balance done)
