I found the parts needed to finish the empennage fairing. First I have to drill out 7 rivets to begin the installation. Then some trimming has to be done. A seal will be installed between that part and the horizontal stab.

here, a very small lenght of seal is fitted for a try. I'll do the final trimming later as the horizontal stab may have its position adjusted after the wing installation.

The fiberglass fairing needs to be trimmed down to fine moulding lines. I only marked the lines with a Sharpie, I'll do the trimming next time.

Today I fabricated the rudder stops. Here the left side. It's not quite as per plans but it works.

The plan says that with the rudder at full deflection and the elevator at neutral, there should be 1 inch 1/8 between the two controls. I think I'm OK.

Just for fun I installed the empennage fairing/

I'll have to check the plans to see what has to be done there.

The empennage installation goes on. First with the drilling not done yesterday. Here, the part riveted to the veritcal stab's forward spar and bolted to the horizontal tab's forward spar. The joggle in the part allows the front of the vertical stab to be offset to the left, to counter the propwash.

After having reinstalled the vertical stab, four holes are drilled, they will allow to bolt the rear spar of the vertical stab to rear bulkhead of the fuselage.

Here a picture with all the parts in place. A fairing will be fitted later in the building.

Then I begin installing the rudder stops. The plans are known to be inaccurate, so I only cut the aluminium angle. The angle will then have to be cut so as the green parts touches the angle when the rudder is at full travel.

Today I begun the installation of the empennage. First the horizontal parts get reassembled upside down on the workbench. The first task is to drill the elevator control horns (the greyish part at the center of the controls).

After the drilling of the first side, I use a predrilled wooden block to transfer the hole to the second part.

The horizontal stab gets installed to the fuselage. First the forward longeron with the drilling of four holes , the two outer holes need to be carefully drilled as they have to go through the fuselage longeron too.
The rear spar is easier, the four outer holes in the background had there holes predrilled.

Then I installed the vertical stab, as for the horizontal stab, lots of measurements and adjustments have to be made to get the right position.

Then the elevator stop is installed as the vertical stab will be bolted there.

The forward spar of the vertical stab will be bolted to the forward spar of the horizontal stab via the aluminium color part in the picture. I still have to drill it.

As I'll soon begin the installation of the empennage, I decided to fabricate a few small parts that will be needed: two shims and the elevator stop.

Before drilling the elevator stop I put it into position on the fuselage, to make sure I will be drilling without compromising the edge distances on the fuselage longerons.
