Empennage fairings started

We've been slowly working on section 12 in parallel with other tasks for a number of months.

We started by following the instructions to match-drill and rivet one of the elevator fairings:

Of course, only after riveting this first fairing did we realize that we should have removed some of the gel coat in the gap between the parts to make a smooth joint with filler - so we'll need to somehow do that later.

We drilled and trimmed the horizontal stabilizer fairings to clear the elevators:

We also did most drilling and trimming of the empennage fairing:

I managed to find and drill the other holes using either the backlight trick (though I had to reduce the garage's lights to 1% for that due to the opacity of the gel coat), or with the strap duplicator:

I then trimmed all the fairing's edges per instructions, which for the most part matched the scribe lines pretty well.

After trimming the edges, there are still some gaps between the fairing and the skins, which will have to be filled later:

Since we're installing Aveo Ziptips, we have no reason for a light underneath the rudder. Unfortunately Van's doesn't make a rudder bottom fairing for the -10 without the light protrusion (they do for other RV models), so we had to remove that:

Next steps will include closing that rudder fairing opening, filling the empennage fairing gaps, opening up and countersinking the empennage fairing holes for screws, working on the rudder and VS top fairings (which right now are mounted on the plane, so pretty hard to reach), and laying fiber to close the HS and VS fairing rear openings.

Time lapse:

Total empennage fairing rivets: 22
Total empennage fairing time: 19.2h
