Puncture the covering material directly over these two holes,
on the BOTTOM of the elevator only, to accept the two "pegs" of
the control horn. Use a sharp knife to remove the small strip of
covering material between the two holes. Then glue the nylon
control horn in place on the BOTTOM of the elevator, using thick
CA glue. Apply a small amount of glue to the two pegs and a small
amount of glue to the bottom of the control horn base itself. With
the three small holes in the control horn facing forward, firmly press
the horn into the two pre-drilled holes in the elevator, until the base
bottoms out on the elevator surface. If any glue oozes out onto the
covering, it can be easily removed with SIG CA Debonder.

15) Next, the horizontal stabilizer/elevator assembly is glued
permanently onto the fuselage. To allow enough time to properly
align the stabilizer, we recommend using slow drying SIG Epoxy
Glue for this step.
a) Begin by first mounting the wing to the fuselage using the
provided 4-40 x 1” nylon wing bolts. Place the model on a flat
surface that lets you view it directly from the front.
b) Set the stabilizer in place on the fuselage. Use a small
weight or pins to hold the stabilizer in position. View the model
from the front to see if the stabilizer is properly aligned with the
wing and fuselage, without tilting to one side or the other.
If
necessary, take the stabilizer back off and make slight adjustments
to the fuselage where the stabilizer sits, with a sanding block, until
the stabilizer will sit level.
c) Remove the stabilizer. Mix a small amount of epoxy glue
and apply it to the mating surfaces of the fuselage and bottom of
the stabilizer. Carefully place the stabilizer back on the fuselage.
Again use a small weight or pins to hold it in position. Make sure
the stabilizer is square with the fuselage by measuring from the
trailing edge of the wing back to the leading edge of the stabilizer,
on both sides. Shift the stabilizer slightly if necessary until both
measurments are the same. Wipe off any excess glue using a
paper towel or rag soaked in rubbing alcohol. Allow the glue to dry.
❑
11) Remove the servo arms from the servos. Install the servo
arms on the Z-bend ends of the pushrod wires (if the holes in your
servo arm are too small for the wire, drill out the holes with a #60
or 3/64" dia. drill bit). Then reinstall the servo arms back onto the
servos - do not tighten the servo arm screws completely yet
because the arms may have to be repositioned when the radio
system is tested and centered.
TAIL SURFACES
For this section you will need the horizontal stabilizer/elevator
assembly, the vertical fin/rudder assembly, and 2 nylon control
horns.
❑
12) As received, the elevator is only temporarily attached to the
stabilizer with 4 unglued CA hinges in the pre-cut slots. Refer back
to page 3, step 4 of this manual for instructions on gluing CA
hinges, and use the same proceedures described there to glue the
elevator hinges permanently in place. Let the glue dry a minimum
of 10 minutes before flexing the hinges.
❑
13) Hold one of the white plastic control horns up against the
edge of the elevator. Use a fine tip pen to mark the two pegs on
the base of the control horn for cutting off just below the top
covering of the elevator. Then use a sharp razor blade or hobby
knife to cut off the pegs at the marks.
❑
14) Note that there are two holes pre-drilled in the center of the
elevator, under the covering material, for the control horn mounting.
