Section 3: Installing the Tail
Step 6. Remove the horizontal stabilizer and use a sharp
hobby knife to carefully cut away the covering approximately
1/16” inside the line marked on the horizontal stabilizer so that
bare wood will show.
Caution: Do not cut into the balsa wood,
as this will weaken the structure.
Step 7. Use masking tape to temporarily attach the horizontal
stabilizer to the fuselage, making sure it is aligned with the slots
in the fuselage and no bare wood shows on the bottom.
Carefully slide the vertical stabilizer (with rudder still attached)
into position in the fuselage and horizontal stabilizer. If the fit is
tight, use a sanding stick to remove some of the balsa, but be
careful not to overdo it. Align the vertical stabilizer so the rudder
(still attached) has a slight gap between it and the horizontal sta-
bilizer, as shown below.
Step 8. When you’re satisfied with the alignment, use a
pencil to mark the junction of the vertical stabilizer and fuselage
top. The mark should leave a slight indentation in the covering.
Remove the vertical stabilizer and horizontal stabilizer from the
fuselage. Use a sharp hobby knife to cut away the covering

inside the mark you made. This allows the epoxy to adhere
better to the vertical stabilizer and the fuselage/horizontal
stabilizer. Remember not to cut into the balsa wood, as this will
weaken the structure.
Step 9. Mix up approximately 1 ounce of 30-minute epoxy and
apply it to the area of the horizontal stabilizer that contacts the
fuselage. Make sure the slot of the horizontal stabilizer aligns
with the slot cut into the fuselage top and horizontal stabilizer
mount area of the fuselage. Check the bottom of the horizontal
stabilizer to see that it is aligned to the fuselage and no bare
wood is showing.
