Hi there,
Although my quadcopter flies great in Stabilise mode, it drifts up and down when in AltHold or Loiter mode. I have made sure all my vibrations are within acceptable limits.
The following plot is from the attached log. I have graphed GPS.RelAlt and CTUN.BarAlt. Should BarAlt be fluctuating so widely?
Thanks!

This graph may be more useful - it shows how Altitude tracks Desired Altitude (not very well!)
