3. Using the hardware that came with your servo, set up
two servos as shown and install them into the servo bays.
When installing the servos be sure that you secure the servo
connections with shrink tubing, tape or some other method
for securing the connections.
❏
4. The elevator has a plywood control horn mounting plate
built-in. Place a control horn onto the plate in line with the
servo arm. Drill a 3/32" [2.4mm] hole through each of the
four mounting holes, into the plywood plate. DO NOT DRILL
THROUGH THE OPPOSITE SIDE OF THE ELEVATOR!
❏
5. Install and then remove a #4 x 5/8" sheet metal screw
into the four holes you drilled. Apply a couple of drops of thin
CA glue into the holes to harden the threads. Allow the glue
to harden.
❏
6. Secure the horn to the elevator with four #4 x 5/8" sheet
metal screws.
❏
7. Locate two 4-40 x 5-3/4" [146mm] threaded pushrod
wires, 4-40 nuts, 4-40 threaded clevises, 4-40 solder clevises
and silicone clevis keepers. Use the same procedure used
for making the aileron pushrods and make two pushrod wires
for the elevators.
Install the Rudder
❏
1. Locate four rudder
hinges. Apply a drop of
oil to each of the hinge
points. This will prevent
glue from working into
the hinge.
❏
2. Mix ¼ ounce [2 drams] of epoxy. Apply it to one half of
the hinge and inside the hinge hole in the leading edge of
the rudder. Do this for each of the four hinges and then insert
each of the four hinges into the holes in the trailing edge of
the rudder. Clean any excess epoxy with a paper towel and
denatured alcohol. Set the rudder aside until the glue hardens.
❏
3. Repeat step 2 for the opposite end of the hinge, gluing
the rudder to the fuselage.
