Step 2
Drill 1/16" (1.5mm) holes in the center of each hinge slot,
both the rudder and fin. Locate the three CA hinges, and
place T-pins in the center as shown. Install the hinges in
the rudder. Test fit the rudder to the fuselage. Use tape
to hold the rudder in position for the next few steps.

Step 3
Locate the metal clevis 4-40 nut, clevis retainer and
nylon ball link. Thread the 4-40 nut onto one end of a
4-40 x 5" (127mm) threaded rod. Slide a clevis retainer
onto a metal clevis and thread the clevis up against the
nut. A small amount of the rod will be visible between
the forks of the clevis. Tighten the nut against the clevis
to prevent it from loosening. Thread the nylon ball end
onto the other end of the threaded rod. Attach the ball
end to the servo arm 1" (25mm) from the center of the
servo using a 4-40 x 1/2" screw and 4-40 locknut.
Note : It is suggested that threadlock be
used on the nut and clevis to prevent
them from loosening during flight.
Note : Attach the ball end so it will be
on the inside of the control horn.

Step 4
Plug in the rudder servo and turn on the radio
system to center the servo. Place the servo
arm on the rudder servo as shown.
Note : See the section of setting the
control throws and adjusting the travel
adjustment before proceeding.

Step 5
Use the radio to move the rudder servo to the
full right position. Align the rudder pushrod so
it is parallel to the elevator. Mark the location
where the pushrod crosses onto the rudder.
