12) With both elevator halves and the servo arm
centered, tighten the set screw in the adjustable servo
connector. Remove the excess wire using wire cut-
ters. See photo # 44 below.

13) Remove the masking tape from the elevator
halves. Adjust each elevator half by turning the cle-
vises in or out until both elevator halves are centered.
PARTS REQUIRED
q
{2} 2mm x 250mm Threaded Wires
q
{2} Nylon Control Horns w/Backplates
q
{4} 2mm x 25mm Machine Screws
q
{2} Nylon Clevises
q
{2} Adjustable Servo Connectors
AILERON LINKAGES
INSTALLING THE CONTROL HORNS
q
1) The centerline of the control horns are located
2-5/8” out from the inside edge of each aileron. Posi-
tion the control horns on the bottom of the ailerons
with the clevis attachment holes directly in-line with
the hinge lines. The control horns should also be par-
allel with hinge lines as well. See figure # 20 below.
Figure # 20
q
2) When satisfied with the alignment, use a
3/32” drill bit and the control horns as a guide and
drill the mounting holes through the ailerons.
q
3) Mount the control horns to the ailerons by
inserting the 2mm x 25mm machine screws through
the control horn mounting bases, through the aile-
rons and into the backplates. Tighten the screws,
but do not overtighten them. You do not want to
crush the wood.
q
4) Thread one nylon clevis onto one 2mm x
250mm threaded wire. For security thread the clevis
on no less than 5/16”.
q
5) Install one adjustable servo connector onto the
outermost hole in one aileron servo arm. You may
have to enlarge the hole in the servo arm to accommo-
date the servo connector. See figure # 21 below.
Figure # 21
After installing the adjustable servo connector
apply a small drop of Kwik Bond thin C/A to
the nut. This will prevent the connector from loosen-
ing during flight.
q
6) Slide the pushrod wire through the hole in
the adjustable connector. Connect the nylon clevis to
the third hole down in the control horn.
q
7) Use a couple of pieces of masking tape to hold
the aileron in neutral. Connect the leads of the Y-
harness to the two servo leads and plug the Y-harness
into the receiver. Center the servo, tighten the set screw
in the adjustable servo connector and remove the ex-
cess wire using wire cutters. See photo # 45 below.

q
8) Repeat steps # 4 - # 7 for the second aileron
linkage.
q
9) Remove the masking tape from both ailerons.
Check to make sure both ailerons are centered. If
they are not, adjust the length of the linkages using
the clevises or servo connectors.
