Wings

Tank Leak Test, Autopilot installation  ( 3 hrs )

LH tank testing:  Only place I've been identifying leaks was at the balloon attached to the tank.   Replaced balloon, applying thread sealant prior to slipping onto fitting.  Used band of strong tape, followed by safety wire twisted tight (thanks Vans Air Force for tip to use safety wire/pliers !).  Finally....no bubbles at balloon attach !    Now I can concentrate on confirming no other leaks.  So far all I could reach showed no signs of bubbles w/ generous applications of soap suds.
 

Started Optional Sect 56 - Garmin Autopilot Servo install kit.   Bolted on Roll Servo Brace in right wing, built 1 Pushrod for Pitch servo, and 1 Pushrod for Roll Servo (1/8" longer).  That all I can do in the wing until I purchase the Garmin Servo - which I probably won't buy until I purchase the Garmin G3X avionics (displays, etc).
Powder coated white brace added to bellcrank mount on Right Wing Spar
Looks simple, but alum tubes required drilling and taping for 1/4-28 threads.
Getting started on the Optional Sect 38 -  Electric Aileron Trim.  Drilled #30 holes & deburred mounting brackets.
