Avionics

Avionics mounting ( 4 hrs )

Installed LH & RH Cabin Heat Control Cables after cutting to 36" lengths per Sect 50-07.  Needed to insure Avionics would not interfere.  Remainder spent exploring specific location & orientation on co-pilot side sub-panel.   Lots of connector and harness routing concerns to work out.  Step by step gaining clearer strategy.  Started fabrication of piano hinges to mount GTX-45R transponder.   Nick Millard at Stein Air has been helpful answering several questions.

GTX-45R: under glove box, foward to clear stuff on lower RH
instrument panel, while leaving room on left for connectors. 
GEA24 concept on sub-panel clears large connectors.

Fabricating piano hinges.

Empennage Fairing ( 3 hrs )

Completed filling pinholes using epoxy/micro balloons, followed by sanding.  Then re-coat with Cromax Quickprime A-4240S (purchased another 14oz spraycan at National Coating and Supplies  store).  Final wet sanded with 600 grit to prep for painting later.   So...H.Stab and V. Stab removed and back into storage.   Laid out strategy for GTX-45R Transponder mounting (on RH area under glovebox) using 2 piano hinges, etc.

Emp Fairing final sanded w/ 600 grit after filling pinholes.   Four Intersection Fairings in background rec'd same process.

Finished sanding smooth where I filled pinholes.  Sprayed Cromax Quickprime A-4240S (sandable, acrylic primer) on Emp Fairing and 4 Intersection Fairings.   Looking good!  But some pinholes remain, so another round of fill, sand, prime soon.

Used most of can on canopy transition,  so ran out
 before I could fully cover both Upper Int Fairings...

Tah Dah !

Empennage Fairing ( 2 hrs )

Mixed epoxy/flox and filled pinholes on Emp Fairing (also some on 4 Instersection Fairings).   Later, after cured 6 hrs, sanded smooth all 4 Intersection Fairings and Empennage Fairing.    Began exploring where and how to mount various units supporting Garmin G3X system:  GTX-45 ( remote transponder w/ ADS-B in/out), GEA24 (engine monitor), GD-40 (CO detection), GPS20A (remote WAAS GPS), and GAD27 (intergrated controller).   Referenced couple other RV14 builder logs, and Layout provided by Stein Air.

flox mix added to fill pinholes ( prior sand smooth... again)

unpacking Avionics...

Empennage Fairing ( 3 hrs )

Completed sanding high spots and contoured at HS leading edge.  Removed Fairing ( Yay !  - some prying required, but did come off...whew...) to sand edges.  Smoothed edges all around using 120 grit.  Removed excess flox underneath using dremel.  Ref Step 5 at 12-13.  Pleased with fit when re-attached.  No gaps !   Got a lot of pinholes opened via removed layer of filler/paint...so will tackle those next.

Empennage Fairing ( 1 hr )

Wet sanded most of Emp Fairing with 80 and 120 grit to remove waviness and high spots.   Good progress, but more needed.

Empennage Fairings ( 4 hrs )

Per Sect 12-13, final trimmed Fairing edges to within 9mm of holes.  Covered Fuse, HS, and VS contact areas with cellophane packing tape (then applied auto wax for good measure).  Mixed epoxy/flox to smooth, slight sag mix then applied to underside Fairing in marked areas.   Tried not to smear all over VS as I positioned onto Fuse/HS/VS.   Inserted 27 screws followed by major clean up.  Several hours later, I began sanding to eliminate slight waviness and taper toward edge.   Lots of sanding to do next.  (I'm praying the Fairing comes off, but gonna wait until more rough sanding done)

trimmed edges, re-installed

clear tape, then car wax applied as extra release

Underside sanded where flox will be attaching

after clean up, starting to cure.  

later, after cure, began to sand.  Shows how
waviness is being eliminated.  Will have consistent
edge contacting alum, with no gaps.
