❑
Install the 90º bend in the threaded elevator pushrod wire
into the hole that you just enlarged, using the nylon snap keeper
provided. When installing the snap keeper, make sure it
"snaps" firmly into place over the pushrod wire.
☞
The pushrod wire should be orientated on the bottom of
the servo arm, as shown.
❑
Thread one nylon clevis onto each elevator pushrod wire.
When the clevises are in the correct position, the distance
between the 90º bend in the pushrod wire and the nylon clevis
pins should be 9-3/16".
☞
Hold the pushrod wires with a pair of pliers to prevent them
from turning while installing the clevises.
❑
Connect your radio system and plug the elevator servo into the receiver. Double-check that the elevator trim lever on
your transmitter is centered.
❑
Slide the pushrod assembly into the servo hatch and through
the support bulkheads.
❑
Install the servo horn onto your servo, making sure that it's
centered and pointing toward the middle of the fuselage,
as shown.

Before installing the elevator pushrod assembly, it's very important to apply a couple of drops of thin
C/A to the machine screws in the wheel collars that secure the two elevator pushrod wires together. This will prevent the
screws from loosening during flight. Do not omit this procedure or failure of the elevator control system could result!
It's important that you install the wheel collars in the location shown on the full-size drawing. This will prevent the wheel
collars from hitting or otherwise interfering with the plywood support bulkheads in the back of the fuselage. Positioning
the wheel collars further forward or further back could result in them hitting the plywood support bulkheads during use.
❑
Using a modeling knife, cut away all but one arm from a "4-point" servo horn.
❑
Enlarge the hole in the servo arm that is 9/16" out from the center of the servo arm, using a 5/64" diameter drill bit.
❑
Install and tighten the servo horn retaining screw to secure the servo horn to the servo.
❑
Use a couple of pieces of masking tape, taped between the elevator halves and the stabilizer, to hold the elevator
halves centered.
