My autopilot works great in level flight, climbs, and descents. the servos do not slip as it transitions to climbs and descents.
During an approach to an ILS I arm the localizer and glide slope. The autopilot intercepts the localizer and switches to localizer tracking. Tracks just fine.
I intercept the GS from below. the instant the autopilot intercepts the GS and switches to GS mode the stick starts oscillating forward and aft at about 1 second intervals. The nose of course follows along rising about 3 inches and then dropping back down. I let it go for about 15 seconds a couple times while I adjusted the trim with no improvement.
Any ideas?
Autopilot settings are:
Torque 100%
Sensitivity 13
Pitch gain 2.2
Altitude gain 1.5
Pull rate 1.0
VSI gain 1.5
G error gain 3.0
G error limit .25
Default climb 500
Default descent 500
Max AS 180
Min AS 81
