Dynaflite GPMA1052 Bird of Time - Manual (Page 9)

❏
1. Cut three hinges from the supplied CA hinge
material to a size of 3/4" x 1" [19 x 25.4mm]. Snip
the corners off to make the hinges easier to
insert into their slots. Fit the CA hinges in the
precut slots in the rudder and vertical fin. If the
slots are tight, use a hobby knife to widen the
slots. Insert the knife in the slot and rock it back
and forth. It is the rear of the knife blade that
does most of the work. When satisfied with the
fit, glue the hinges in place with six drops of thin
CA on each side of the hinges. DO NOT use any
accelerator. Be sure to leave enough of a gap so
the rudder can reach full deflection.
❏
2. Thread a nylon clevis on the 36" [915mm]
wire pushrod at least 13 full turns. Install a
silicone retainer on the clevis. Insert the pushrod
into the tube in the fuselage. Install a control
horn on the clevis using the hole furthest out on
the horn. Mark the location of the mounting
screw holes on the rudder. Drill 3/32" [2.4mm]
holes for the screws and mount the control horn
to the rudder with the 2-56 x 5/8" [15.9mm]
machine screws and the nylon back plate. Note
that the holes in the front of the control horn (for
the clevis) are in line with the hinge line. Trim the
corner of the control horn and the nylon
backplate as shown in the picture above.

3. Mark the location of the mounting holes for
the rudder servo on the servo tray in the nose of
the fuselage. Drill pilot holes and install the
screws that came with your servo. Remove the
screws and harden the holes with some thin CA.
❏
4. Mount the rudder servo with the grommets,
eyelets and screws supplied with your servo.
Place a servo arm on the servo perpendicular to
the servo. With the rudder centered, mark the
rudder pushrod where it crosses the outer hole in
the arm. Bend the wire up 90 degrees at the mark.
Secure the wire to the servo arm with a nylon
Faslink connector and cut off the excess wire.
Install the retaining screw for the servo arm.
