D 3. Pin the elevator tips in position over the plan. Cut the
elevator outer frame from 1/4" x 3/8" x 30" balsa sticks.
Glue the elevator outer frame and tips together. Make sure
each elevator LE is straight as you glue it in position. Glue
the elevator joiner wire doublers to the elevator LE'S.
D 4. Position the stab and elevators over the plan and
mark the location of the elevator joiner on the elevators.
D 4. From a 1/4" x 3/8" x 30" balsa stick, cut and glue the
two gussets to the elevator frame and tips.
D 5. Drill a 3/32" pilot hole into the elevator LE, on the
centerline, at the torque rod marks. As you drill the holes,
keep the drill aligned with the top and bottom surfaces of
the elevator. Enlarge the holes with a 1/8" drill bit.
D 5. From the 1/4" x 1/4" x 30" balsa stick, cut and glue
the elevator ribs to the elevator frame.
D 6. Remove the elevators from your building board.
Inspect all the glue joints and add CA to any joints that
don't look strong. Sand the joints flush and the entire top
and bottom surface of the stab flat and even. Be careful
that you don't sand any area too thin.
D 6. Cut a 1/8" groove in the leading edge of both
elevators to recess the joiner wire. Do not glue the joiner
wire in position at this time.
D 7. Remove the elevators from the stab. Mark the "bevel
to" lines and sand the LE of the elevators to a "V" as shown
on the plan.
D 1. Place the stab and elevator over their locations on the
plan and lightly mark the hinge locations on the TE of the
stab and LE of the elevator. D 8. Draw a centerline on the LE of the stab and the TE of
the elevators. Sand a radius on the LE of the stab and the
TE of the elevators, referring to the cross-section on the
plans as a guide.
D 2. Make six 3/4" x 1" elevator hinges from the remaining
2" x 9" hinge material.
D 3. Mark the centerline of the hinges on the stab's TE and
elevator's LE. Cut the hinge slots and without using glue,
test fit the elevator on the stab.
This completes the stab and elevators. Put them aside for
now and let's move on to Building the Wing.
