❑
Using Magnum Z-Bend Pliers, make a Z-Bend in the pushrod wire at the mark you drew and use wire cutters to
remove the excess wire.
❑
Remove the servo horn. Using a 1/16" drill bit, enlarge the hole in the servo arm that is 1/4" out from the center of the
servo horn.
❑
Attach the servo horn to the Z-Bend, then attach the servo
horn to the servo, making sure it's centered.
❑
Install and tighten the servo horn retaining screw, provided
with your servo, to secure the servo horn into place.
❑
Install the rudder pushrod wire using the same technique as with the elevator pushrod wire. The Z-Bend should be
installed into the hole that is 1/4" out from the center of the servo horn as well.
IMPORTANT
So that the two pushrod wires don't touch each other where they cross inside the fuselage, install the rudder pushrod wire
so that the long portion of the wire is on the opposite side of the servo arm from the elevator pushrod wire. Doing this will
put the pushrods at slightly different heights, so they won't rub against each other.
❑
Double-check that the elevator and rudder are still centered. If they are out of adjustment, remove the clevises and
readjust them until you are satisfied with the alignment. Unplug and turn off your radio system.
Step 4: Installing the Aileron Servo
❑
Install the rubber grommets and brass collets onto the servo mounting lugs.
❑
Using a ruler and a pencil, measure
back
2-3/4" from the
leading edge
of the wing (at the centerline) and draw a mark
at this location. Do this on the
top
of the wing.
❑
Place your aileron servo on
top
of the wing, aligning the
servo output shaft with the mark you drew.
❑
Center the servo over the wing's centerline and trace
around the base of the servo using a pencil.
❑
Using a modeling knife, carefully cut out the wing to accommodate your servo. Don't cut the hole too large, though.
The servo should fit tightly.
WARNING
For the servo mounting lugs to fit down against the top of the wing, you'll need to remove as much of the foam as possible
from the bottom of the servo cutout. Be careful not to cut through the bottom of the wing!
