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.
