Thank you DB for your report. I have no idea why the vibrations is an issue but what I do know from the old Hobbico gyro that I use in the Quad Kadet is, it is effected directly by temperature but that has been no problem as it just required recentering (the rudder only) before the first flight of the day either through the radio trim (manual or sub trim) or it can be adjusted with a small screwdriver before wing assembly.

Now I am beginning to wonder if simply starting out with excessive gain for any of the axis' is the problem. I do limit my old one to no more than 50%.

Now anyone out there using the Guardian on a glow plane and not a gasser? There could be differences in vibration levels amplitude and frequency there that may make a difference.
