The work continues...

I've painted the cabin floor and covered the fuse top, as I mentioned before. Also glued the stab in its place. To achieve this, I've put the wing and stab in their place; done this, I've measured the stab halves to be equally long at both sides of the fuse and the wing tips distances to the stab tips, to achieve surfaces paralelism. When thhe surfaces were aligned, I've applied some drops of CA to the stab/fuse junctions, just to fix it in place.
Then, I've cut a piece of fiber cloth to fit the internal stab top with some additional width (5mm per sede, approx) to glue it to the internal fuse sides. Painted it with epoxy, and this is the result:
