q Look from the front of the aircraft at both the wing and the stabiliser. When
aligned properly, the stabiliser should be parallel to the wing.
+
If the stabiliser is not parallel to the wing, remove the stabiliser and sand
B B-1
down the higher side of the stabiliser mounting slot until you're satisfied with
the alignment.
STeP 3: InSTAllIng The hORIzOnTAl STABIlISeR
q When satisfied with the alignment, draw a line on each side of the stabiliser
where it meets the fuselage sides. Do this on both the top and the bottom.
WARNING When cutting through the covering material to remove it in the next procedure, cut with only enough pressure to cut through
only the covering material itself. Cutting down into the balsa structure could weaken the stabiliser and cause it to fail during flight.
q Remove the stabiliser from the fuselage, then carefully cut away the
covering material from inside the lines you drew.
PRO TIP Use a heat-sealing iron to adhere the covering material down
where you cut it. This will prevent it from loosening up and wrinkling.
q To make it less messy during installation, apply strips of masking tape to
both sides of the fuselage around the mounting slot, and to the top and the
bottom of the stabiliser, too.
q Apply a generous amount of 30 minute epoxy to the gluing surfaces of both the stabiliser and the fuselage.
q Push the stabiliser into place and realign it, double-checking all of your measurements once more before the epoxy sets up. Remove
any excess epoxy and use T-Pins to hold the stabiliser in place and aligned until the epoxy has fully cured.
STeP 4: AliGNiNG AND iNSTAlliNG The VerTiCAl STAbiliSer
q Cut away the covering material from over the stabiliser mounting slot in the
top of the fuselage. The stabiliser mounting slot is 1/4" (6mm) wide and 6-3/8"
(162mm) long.

STeP 1: iNSTAlliNG The eleVATor SerVo
q Install the elevator servo into the left side of the servo tray (up against the
edge), making sure to drill 1/16" (1.6mm) diameter pilot holes for the servo
mounting screws.
IMPORTANT Note the orientation of the servo. When installed, the servo
output shaft should be toward the front of the fuselage.
STeP 2: iNSTAlliNG The eleVATor CoNTrol horNS
q Cut away the covering material from over the elevator pushrod exit hole in
each side of the fuselage. The pushrod exit holes are located 4" (102mm) in
front of the rudder hinge line and 1-1/8" (29mm) below the stabiliser.
q Position and mark the mounting hole locations for one control horn on the
bottom of one elevator half. When aligned properly, the centreline of the control
horn should be 1" (25mm) out from the fuselage side (measured at the hinge
line) and the clevis attachment holes should be lined up over the hinge line.
The base of the control horn should be angled slightly toward the fuselage side
so that it will line up with the pushrod wire.
q Drill 5/64" (2mm) diameter pilot holes through the elevator half for the control
horn mounting screws, then apply a couple of drops of thin C/A into the pilot
holes and allow the C/A to fully cure.
+
The C/A will harden the surrounding wood, making the mounting area
stronger.
