Use a couple of pieces of masking tape, taped between the elevator and the stabilizer, to hold the elevator centered.

cable guide to the Z-Bend coupler on
the
right side
of the servo arm, using the same techniques that you used
to attach the threaded couplers.
IMPORTANT
Make sure that both lengths of cable are pulled tight.
There should not be any slack in the cables.
q
Remove the masking tape and double-check that both the servo horn and the elevator are still centered. If necessary, thread
the clevises in or out to center the elevator, then move the elevator up and down several times to ensure proper movement.
q
Check the tension of the cables. To do this do the following: hold the elevator control stick all the way back. Let the control stick
go and check to see if the elevator returns to center. Do this a couple of times in each direction. If the elevator does not come back
to center, one or both cables are too tight. You can adjust the tension of the cables by adjusting the clevises. Ideally, the cables
should be as tight as possible, while still allowing the elevator to center. The cables should not have slack in them, yet they should
not be so tight that the linkage and/or the servo bind.
IMPORTANT
Remember to apply a couple of drops of thin C/A to the crimp collets to make the joints even stronger.

q
Install the rudder servo onto the hardwood mounting blocks, making sure
to drill 1/16" (1.6mm) diameter pilot holes for the mounting screws.
IMPORTANT
When installed, the servo output shaft must be toward
the
front
of the fuselage.
q
Install the rubber grommets and brass collets onto your rudder servo, making sure to install the collets with the flanges toward the
bottom
of the servo.
IMPORTANT
The rudder control system is installed using the same basic techniques that you used to install the elevator control
system. There are a couple of differences that are noted for you.
