ALIGN THE STAB HORIZONTALLY
❏
1. Place two clothespins on the top of former F4
and rest a straightedge on the top of the fuse sides,
propped up against the clothespins. See the
following photo.
❏
2. Stand behind the fuselage and view the stab
and the straightedge to see if they align. If
necessary, carefully sand one side of the stab saddle
so the stab will align with the straightedge.
Note
: If you have an incidence meter and want to
check the incidence of the stab, now is a good time
to do so. The incidence should be +2 degrees in
relation to the main fuselage stringer.
❏
3. Center the rudder clevis/nylon horn in the
clearance slot in the stab saddle. Move the rudder
pushrod wire back and forth to make sure the clevis
and horn do not interfere with the fuse sides and the
rudder torque rod can move freely. If necessary,
adjust the pushrod wire or the
clearance slot in the
stab saddle.
There must not be any possibility of
binding here
.
❏
4. Mix 1/2 oz of 30-minute epoxy. Reinforce the
joint between the stab saddles and the main
stringers. Glue the stab to the saddles. Place the
stab on the saddle so the marks you made earlier
align. Before the epoxy cures, confirm alignment
once more using the
pin and string technique. Do not
proceed until the epoxy has fully cured.
MOUNT THE FIN
❏
1. If you have not already done so, sand the
sheeting on the bottom of the fin even with R1. Place
the fin on the stab with the TE resting against the
rudder torque rod. Mark the bottom of the fin at the
front of fuselage former F10A.
❏
2. Cut a stick 4-7/8” [124mm] long from the leftover
1/4” x 3/8” [6.4 x 9.5mm] basswood stick. Cut a hole
in R1 on the bottom of the fin for the stick. The hole
should be forward of the mark you made, towards
the LE of the fin. Insert the stick into the fin and
check the fit of the stick and fin on the fuselage. The
stick should extend to the hole for the receiver
antenna tube in former F10 and should touch R2
inside the fin.
❏
3. Check that the fin is vertical in relation to the
stab. Use the
pin and string technique or a ruler to
measure the distance between the tip of the fin and
the stab tips. Use an incidence meter or carpenters
level to also check that the TE of the fin is
perpendicular to the main fuselage stringer. Make
any adjustments necessary.
❏
4. Mix some 30-minute epoxy. Glue the basswood
stick into the fin making sure to put epoxy on the end
of the stick that touches R2 inside the fin. Glue the fin
and stick to the top of the stab and to former F10.
