9. When the stab is correctly aligned, outline on
both the top and bottom of the stab where it
meets the fuse, as shown.
10. Remove the stab from the fuselage. Being
careful to not cut into the wood, and work-
ing about 1/8” inside the outline on the stab,
lightly cut away the covering on both the bot-
tom and top of the stab.
Replace the stab on the fuselage, but DO
NOT GLUE AT THIS TIME.
11. Slide the fin into the back slot and push the
fin front down into the top slot.
When the fin is all the way down and flush to
the fuselage, mark a line on both sides of the
fin where it meets the fuselage.
12. Locate the solid wood area under the cover-
ing and place marks on the line where the
wood ends. Make sure not to mark any open
frame areas.
13. Staying at least 1/4” away from the open
frame, carefully remove the covering on
those areas of the fin (both sides) that are
inside the fuselage.
14. Replace the fin on the fuselage and check to
see that the fit is good and the alignment
square.
When you are satisfied with the fit, remove
the fin.
Mix 2-3 tablespoons of epoxy and, using a
stick or an acid brush, spread epoxy down
inside the fin slot, along the walls of the slot,
and on top of the stab.
Glue the stabilizer and the fin to the fuselage
and, using the measuring string and a 90º tri-
aangle, check to see that the tail assembly is
square. Allow to dry thoroughly.
