E-flite Super Airliner DF ARF - Manual (Page 27)

 1. Position the rudder into the slot on the top of the
fuselage. Measure from the tip of the rudder to
each stabilizer tip to make sure the measurements
are equal. If not, lightly sand the bottom of the
rudder to position it evenly.
 2. Use 6-minue epoxy to glue the rudder into
the fuselage. Allow the epoxy to fully cure
before continuing.
 3. Enlarge the outer hole of the rudder servo arm
using a 5/64" (2mm) drill bit. Attach the pushrod
connector to the servo horn. Install the servo
into the fuselage then attach the servo horn after
centering the rudder servo.
