Dec 02, 2019     Aft Fuselage: Fairings - (2.0 hours)       Category: Empennage

Nov 30, 2019     Aft Fuselage: Trim Tab and Rudder Attachment - (6.0 hours)       Category: Empennage
Returned to trim tab assembly. Used RTV to glue foam ribs and set aside with weights overnight. Removed v. stab and final drilled two 1/4" h. stab attachment holes. Reattached v. stab and installed rudder assembly. This took some time to get the three eyebolts aligned. Did not final torque any bolts at this time since it will all need to come apart again later.

Measured torque tube to aft spar gap 9/64" greater than min required. Drilled hole through horns for attachment to clevis joint. Needed to turn down e-drill bushing to fit and pre-drilled #30 on drill press. Drilled hole in horns for later attachment of control rod.
