ight along the vertical stabilizer to the rudder and from the horizontal stabilizer to both elevators and make any
n
ecessary adjustments to the length and tension of each pull-pull cable to center the control surfaces and to ensure
the rudder and both halves of the elevator are all at their ‘neutral’ position with their servos centered [06:22].
Once the pull-pull cables are adjusted, secure both ends of each cable by snugging the lock
nut on each brass pull-rod against its clevis, then permanently anchor each brass pull-rod
in its clevis with a few drops CA.
10. Drill a 1/16-inch hole in each elevator and the rudder control horn, centered between the existing hole for the pull-
pull cables’ clevise and the threaded metal rod.
11. Locate the two small predrilled holes at the trailing edge of each elevator. Run a sharp pin through each predrilled
hole to fully open the covering material at both sides of each hole.
12. Identify and unwrap the coil of wire containing 3 ea. 120 cm (47-
inch) lengthes of wire. (Careful: Don’t kink the wires!)
13. From the bottom side of either elevator, insert the end of one of
the 120 cm (47-inch) wire into the predrilled hole in the bottom of
the elevator that is nearest to the rudder. (Photos show the right-
side’s elevator.) Pull approx. 90 cm (35 inches) of this wire
through the hole to the top side of the elevator (i.e., Leave approx. 30 cm [12 inches]
of wire at the bottom of the elevator). Insert the end of the wire which now prodrudes
from the top of the elevator into the hole in the elevator’s top control horn from the
side furthest from the rudder (i.e., Point end of the wire toward the rudder). Pull the
wire through the control horn’s hole and around the control horn, then insert the wire’s
end into the predrilled hole that is furthest from the rudder [06:41].
14. Bring the two ends of the wire together at the bottom of the elevator and slide a crimp
tube onto these two ends. Insert the wire’s ends into opposite sides of the hole in the
elevator’s bottom control horn. Use pliers to tighten the wire evenly across both
sides of the elevator; then use pliers to securely clamp the wires’ ends within the
crimp tube [07:12]. Trim/cut off and discard the excess wire ends.

15. Install a second 120 cm (47-inch) wing wire on the other half of the elevator by repeating steps 13 and 14.
16. Starting from the left side of the rudder, insert approx. 90cm (35 inches) of the remaining 120 cm (47-inch) wire
through the small opening near the top of the rudder [i.e., Leave approx. 30 cm (12 inches) of wire at the left side of
the rudder]. Insert the wire’s end which now projects from the rudder’s right side into the bottom side of the hole in
the rudder’s right control horn (i.e., Point the wire’s end upwards).
