Install the Horizontal Stabilizer & Rudder
❏
1. Draw a line on the center of the top and bottom of the
horizontal stabilizer. The top of stab has the control horn
slot on the right side of the elevator.
❏
2. Lightly scuff the surface of the stab using sandpaper 5/64"
[2mm] on both sides of the line drawn in step 1. Wipe the area
with denatured alcohol. Do this on both the top and bottom of the
stab. Position the stab onto the back of the fuselage. Using the
line drawn in step 1 as a reference, position the stab making
sure the stab is parallel to the wing. When you are satisfied with
the fit, glue the stab to the fuselage.
❏
3. Glue the vertical stabilizer/rudder into the slot in the
fuselage and the top of the horizontal stabilizer. Hold it in
place until the glue hardens.
Install the Tail Servos & Linkages
❏
1. Glue the rudder and elevator servos into the cutout in
the fuselage with the output splines both facing the front of
the plane. The servo in the bottom of the slot is the rudder
servo and should be installed with the splines on the left
side of the fuselage. The servo in the top of the slot is the
elevator servo and should be installed with the splines on
the right side of the fuselage. Both servo leads should exit
out of the right side. There is a small circle cutout in the
fuselage to allow the lead from the elevator servo to get
access to the right side of the fuselage.
❏
2. Using the same technique used for the ailerons, install
a control horn onto the left side of the rudder and one on the
bottom of the right elevator half.
❏
3. Use your radio system to center the elevator and
rudder servos. Cut three arms from two four-arm servo
horns and install them onto the elevator and rudder servos,
both pointing downward. Enlarge the outer holes of the
servo horns with a 3/64" [1.2mm] drill bit. Enlarge the inner
hole of the control horns (closest to the elevator and rudder)
with the same size bit.
