o 6 . Use your radio to center two servos . Remove the servo
arms and set one servo aside for now . Fit a long servo
arm to your elevator servo . Choose the spline position that
allows one arm to extend from the left side of the servo case
perpendicular to the case body . Clip off the remaining three
servo arms . Use a #48 drill bit to drill the second to the last
hole outboard on the servo arm (about 1/2" [13mm] from the
center of the output shaft) .
o 7 . Fit the elevator servo to the fuselage servo tray as
shown . Align the servo with the two elevator pushrods so
that the pushrods naturally lie over the second to the last
outboard hole on the servo arm . Move the servo left or right
in the tray to achieve this .
o 8 . Use a 1/16" [1 .6mm] drill bit to drill four holes to mount
the elevator servo . Install the elevator servo using the
mounting screws that came with your servo . Remove the
servo and harden the screw holes with thin CA . Reinstall
the servo .
o 9 . Identify the left elevator pushrod and make a gentle
bend in it at the point shown so that it is parallel with the
other elevator pushrod . Set the
right elevator at its neutral
position (zero degrees deflection) and use a felt-tip pen to
mark the point where the pushrod passes over the hole in
the servo arm .
o 10 . Slide two 5/32" [4mm] wheel collars over both elevator
pushrods . Cut the left elevator pushrod 1" [25mm] from
shallow bend you made in the last step . Use a pair of pliers to
bend the other pushrod 90° straight up at the mark that you
made at the servo arm . Install the pushrod onto the elevator
servo using a nylon
FasLink ™ retainer . Cut off the excess
pushrod wire . Cut the wire about 1/8" [3 .2mm] from the
surface of the nylon finger to ensure that the FasLink stays
securely connected . Note: If you removed your servo arm to
install the pushrod and FasLink
™ , make sure you reinstall the
servo arm retaining screw .
