d) Use a pair of pliers to firmly grasp the pushrod wire at the
mark just made, and then bend the plain end of the wire 90
O
UPWARDS. Make the bend as sharp as possible.
e) The excess length of pushrod wire can now be cutoff,
leaving a 3/16" end leg to pass through the control horn hole. Use
a good sharp pair of wire cutters to do this.
f) Insert the bent end of the pushrod wire in the hole in the
control horn, from the bottom. Then slide the nylon pushrod keeper
up to the control horn and snap its tab end over the exposed wire.
g) Remove the tape holding the rudder in neutral position.
❑
20) Now we complete the aft end of the elevator pushrod. Start
by centering the elevator servo output arm in neutral position. Use
a small piece of tape to hold the elevator in neutral position.
a) Slide one of the nylon pushrod keepers over the aft end of
the elevator pushrod wire.
b) Hold the aft end of the elevator pushrod wire against the
side of the nylon control horn and use a fine tip pen to mark the
exact position of the control horn hole on the wire. Note: The wire
will be installed in the 2nd hole from the end of the horn.
c) Temporarily remove the elevator servo output arm from the
servo.
This will allow you to pull the elevator pushrod farther
outside the rear of the fuselage, to make the next step easier to do.
d) Use a pair of pliers to firmly grasp the pushrod wire at the
mark just made. Look inside the fuselage to make sure that the
Z-bend end of the pushrod is parallel to the jaws of your pliers.
What we're getting ready to do is bend the aft end of the pushrod
wire 90
O
SIDEWAYS to the fuselage - meaning, sideways when the
servo arm is re-installed on the servo. If needed, readjust your grip
on the wire so that you can bend the wire in the right direction.
When ready, bend the aft end of the pushrod wire 90
O
. Make the
bend as sharp as possible.

16) As received, the rudder is only temporarily attached to the
fin with 3 unglued CA hinges in the pre-cut slots. Refer back to
page 3, step 4 of this manual for instructions on gluing CA hinges,
and use the same proceedures described there to glue the
elevator hinges permanently in place. Let the glue dry a minimum
of 10 minutes before flexing the hinges
❑
17) Mount a nylon control horn on the LEFT SIDE of the rudder.
Refer back to steps 13 and 14, where we cut off the pegs of a
control horn and glued then glued the horn to the elevator - use the
same steps to prepare and install the control horn for the left side
of the rudder.
❑
18) The fin and rudder assembly is now glued in place on top of
the stabilizer and fuselage, again using SIG Epoxy Glue.
a) First trial fit the fin/rudder in place, without any glue. If
needed, make adjustments to the bottom of the fin to allow full
contact with the top of the stabilizer and the fuselage.
b) Mix a small amount of glue and apply it to the bottom edge
of the fin and to the sides of the fin leading and trailing edge stubs.
Carefully set the fin/rudder assembly in place on the fuselage.
Make sure that the fin is 90° to the horizontal stabilizer.
Use
low-tack masking tape to hold the fin in correct position. Wipe off
any excess epoxy using alcohol and paper towel. Let the glue dry.
❑
19) Now we complete the aft end of the rudder pushrod. Start
by centering the rudder servo output arm in neutral position. Use
a small piece of tape to hold the rudder in neutral position.
a) Slide one of the nylon pushrod keepers over the aft end of
the rudder pushrod wire.
b) Hold the rudder pushrod wire against the side of the nylon
control horn and use a fine tip pen to mark the exact position of the
control horn hole on the wire. Note: The wire will be installed in
the 2nd hole from the end of the horn.
