3. On the left side of the fuselage, slide one wire into the
opening closest to the back of the fuselage. Install a large
nylon control horn onto the clevis. Position the control horn on
the rudder so that the clevis pin is in line with the hinge line.
Mark the location for the screw holes. Drill through the marks
you made with a 3/32" [2.4mm] drill bit, drilling only into the
plywood plate. Do not drill through the rudder! Install and then
remove four #4 x 1/2" [12.7mm] sheet metal screws. Apply a
couple drops of thin CA into the holes. Once the glue has
cured, mount the horn to the rudder with the screws.
❏
4. Install the two elevator pushrods using the same
procedure used for the rudder. Be sure when installing the
control horn on the left elevator that you install it so it does
not conflict with the rudder control horn.
❏
5. Place your rudder servo into the servo tray as shown.
Drill a 1/16" [1.6mm] hole through each of the mounting
holes. Remove the servo, then install and remove a servo
mounting screw into each hole. Apply a couple drops of thin
CA into the holes to harden the threads. When the glue has
cured, permanently mount the servo to the servo tray.
❏
6. Center the rudder and the rudder servo. Then, install
the servo arm. Install a metal solder clevis in the last hole in
the servo arm. Mark the pushrod wire at the end of the clevis.
❏
7. Remove the rudder pushrod and solder clevis from the
plane. Position the clevis next to the rudder pushrod so that the
clevis aligns with the mark. Cut the rudder pushrod as shown.
❏
8. Use silver solder to solder the solder clevis onto the
end of the rudder pushrod.
