Hi,
I just got my Trutrak ADI Pilot I hooked up. I was pretty alarmed by the horribly loud growling noise the roll servo makes, and it kind of resonates in the structure.
I checked the set-up from the factory and they had the 'activity factor' set at 7 rather than the 1 - 2 that the manual recommends. I turned it down to 2, and that did help some, just because the servo doesn't dither as much, nor move as quickly.
But still, every step of the stepper motor makes a pretty loud noise, and when it moves a bunch of steps, its a pretty loud growl.
I did buy the servo second-hand, so now I'm wondering if there is something wrong in the gear reduction that is making so much noise, or if it is normal.
This is in an RV-8, so it is mounted under the floor behind the spar.
