24) Center the servo cover assembly over the servo
bay. Use a couple of pieces of masking tape to hold the
cover assembly in place. See photo # 8 below.
☛
Even though there is a right and left servo cover, it
doesn't matter whether the molded fairing is positioned
toward the wing root or the wing tip. The second servo
cover will be orientated the same way.
❑
25) Repeat steps # 21 through # 24 to temporarily
install the second servo cover assembly in the opposite
wing panel.
INSTALLING THE AILERON LINKAGE
❑
26) Working with one wing panel for now, place
one nylon control horn onto the bottom of the aileron.
The control horn should be perpendicular to the hinge line
and its centerline should be directly behind the middle of
the molded fairing. The clevis attachment holes should
be located directly over the hinge line, too.
❑
27) When satisfied with the alignment, use a drill
with a 5/64" drill bit and the control horn as a guide, and
drill the two mounting holes through the aileron.
❑
28) Set the control horn back into place and re-
align it. Push two 2mm x 12mm machine screws into
the base of the control horn and through the aileron. See
photo # 9 below.
❑
29) Place the nylon backplate onto the machine
screws, aligning the two holes in the backplate with the
two screws. Using a # 0 phillips screwdriver, evenly
tighten both machine screws to draw the backplate into
place. Be careful not to overtighten the screws. You don't
want to crush the aileron.

30)
Thread one metal clevis onto the end of one
2mm x 300mm threaded pushrod wire. Thread the clevis
on far enough to leave room for adjustments later.
❑
31)
Snap the clevis into the third hole out from the
base of the control horn. Using a pencil, draw a mark on
the pushrod wire where it approximately crosses the cen-
ter of the servo horn. This mark should be about 2" in
front of the back edge of the clevis.
☛
Remember, the servo horn should be 1" in front of
the back edge of the servo cover.
❑
32)
Remove the pushrod assembly. Using Magnum
Z-Bend pliers, make a Z-Bend in the wire at the mark you
drew. Use a pair of wire cutters to remove the excess
wire. See photo # 10 below.

❑
33)
Remove the servo cover assembly from the
wing, then remove the servo horn from the servo. Using
a drill with a 5/64" drill bit, enlarge the fifth hole out from
the center of the servo horn.
❑
34)
Attach the servo horn to the Z-Bend, then at-
tach the servo horn to the servo, making sure it's centered.
Install and tighten the servo horn retaining screw, pro-
vided with your servo, to secure the servo horn into place.
❑
35)
Set the servo cover assembly back into place
and realign it. Use four 2mm x 6mm wood screws to
secure it to the wing. See photo # 11 below.

☛
There is 3mm thick plywood preinstalled under the
wing sheeting for the wood screws to thread into.
❑
36) Use a couple of pieces of masking tape, taped
between the aileron and the wing, to hold the aileron
centered.
