Important: Do not allow the wing to shift during this
procedure.

4. Remove the wing and use a 1/4" [6.4mm] drill bit to

enlarge the hole in the wing only.

5. Use a 1/4-20 tap to cut threads into the bolt plate. After

cutting the threads, put a couple of drops of thin CA on the
threads in the bolt plate. Allow the CA to cure before
threading the tap back through the hole to clean up the
threads. Bolt the wing to the fuse with a nylon 1/4-20 wing
bolt
and check the fit.

1. Looking at former F9, note the location of the stabilizer

saddle and the 3/16" x 3/16" [4.8mm x 4.8mm] stringers
above the stabilizer saddle. Cut the fuselage sheeting
between the stringers and stabilizer saddle.

2. Insert the stabilizer in the fuselage. Measure from the

tip of the stabilizer to the fuselage on both sides to center it.
Measure from the center of the front of the fuselage back to
both stabilizer tips. Adjust the stabilizer so that both
measurements are the same. The LE of the stabilizer should
be against the back of former F8A. With the wing mounted
to the fuselage, view the stabilizer from a few feet behind the
fuselage. Check that the stabilizer is parallel to the wing. If
not, remove the stabilizer and sand the stabilizer saddle
slightly. Use a piece of 3-ply left over from a die sheet with
a piece of 220-grit sandpaper attached. When satisfied with
the fit, insert the elevator joiner wire in the slot. Then,
use 30-minute epoxy to glue the stab to the fuselage.
Double-check the stab alignment while the epoxy is curing.
Wipe off any excess epoxy with a paper towel dampened
with denatured alcohol. Check that the elevator joiner wire is
not glued to the stab.

3. Using the joint between the two fuselage base halves,

mark the center of the top deck.

4. Cut the 1/2" x 5/8" x 8" [12.7mm x 15.9mm x 203.2mm]

balsa stick in half to make two fin fairings. Cut a remaining
