D 1. Tape an 8" x 16" piece of waxed paper onto the top
surface of the wing at the center, then attach the wing to the
fuse with the wing bolts.
Method 3: A combination of the above, where you first
glue pieces of balsa to partially fill the fillet area, then add
filler to form the fillet shape.
D 2. Lay the die-cut 1/32" ply wing fillet bases on the
wing and glue them to the fuselage sides. NOTE: For this
procedure, we recommend that you use thick CA glue spar-
ingly, and "kick" the glue with accelerator spray immediately
after applying, to avoid accidentally gluing the wing to the
fuse with "stray" glue. NOTE: Bend the aft 1-1/2" of the
fillet base to horizontal (see sketch).
D 3. You may build the fillet on top of the fillet base in
one of the following ways:
Method 1: Glue pieces of soft balsa onto the fillet bases,
then sand to the fillet shape.
Method 2: Apply a good quality, lightweight model
filler, shape it with a wet teaspoon, and allow it to dry
thoroughly before sanding.
MOUNT STABILIZER AND FIN
D 1. Make sure the stab base is securely glued to the fuse
sides, then lightly sand the stab saddle area smooth with a
T-bar or sanding block. Draw a fuse centerline on the stab
saddle, from the center of F-6T to the center of the aft end of
the fuse.
D 2. Accurately measure the trailing edge of the stabi-
lizer and mark the center point.
D 3. Temporarily mount the wing in the saddle (for
reference), and block up the tips until the wing is level.
D 4. Lay the stab in position on the stab saddle with the
stab centerline lined up with the fuse centerline. The front
edge of the stab should be against the aft edge of F-6T.
Carefully check the stab alignment by measuring down from
the tips to a flat surface, and from the stab tips to the wing tips
(or to a point on the center of the fuse near the nose). Sand the
stab saddle (a little at a time!) until the stab rests in proper
alignment. With the stab in alignment, make a mark on the
front of the stab and a corresponding mark on the back of
F-6T, which will be used for rapid alignment when gluing.
D 5. Mix up a batch of 5-minute or 30-minute epoxy and
apply it to the stab saddle. Press the stab into position and
