Crawled back into the aft end of the fuselage to check the various nuts and bolts that secure the autopilot pitch servo. After checking all the bolts I applied some orange torque sealant to the nuts so I can see at a glance if anything is loosening or moving. The bolts that actually attach the servo motor assembly are safety wired so no sealant is necessary. You should be able to see the orange sealant in the photo below.
