!1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
!2)Removeeachhingefromthe wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. This will help ensure an equal amount
ofhingeisoneithersideofthehingelinewhen
the aileron is mounted to the aileron.
HINGING THE AILERONS.
!3) Slide the wing panel on the aileron until
there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel.A gap of 1/64” or less
shouldbemaintained between thewing panel
andaileron.
!4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The

panel, securely hinging the aileron in place.
!5)Turnthe wingpanel over and deflectthe
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsure thattheC/Apenetratesinto
both the aileron and wing panel.

will be maintained throughout the lengh of the
aileron to the wing panel hinge line. HINGING THE ELEVATOR.
!8)Afterboth ailerons are securely hinged,
firmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully
applying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethat you properlyadhere the
hingesin place perthe steps thatfollow
using a high-quality thin C/A glue.
Note:
The hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistributethroughoutthe
hinge, securely bonding it to the wood
structureofthe wing panelandaileron.
Note:
Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.

arm as same as picture below.
!2) Turn the wing panel right side up. Using
amodelingknife,removethecovering at servo
tray.
Attach the thread to the servo lead and
carefully thread it though the wing.
! 3)Secure the servos with the screws pro-
vided with your radio system.
!6) Reinstall the gear wire and install the
straps using the four 2 x 12mm wood screws.
Tighten the screws completely to secure the
gear wire in place.
Install the rubber grommets and brass collets
onto the aileron servo. Test fit the servo into
the aileron servo mount.
Attach the micro control connector to the
servo arms. Be sure to use the lock tie but it
could free rotation .

and extend this mark, from back to front,
across the top of the stabilizer. Also extend
thismark down theback of thetrailing edge of
the stabilizer.

covering from over the precut hinge slot cut
intothelowerrearportionofthefuselage. This
slot accepts the lower rudder hinge.
!3) While holding the vertical stabilizer
firmly in place, use a pen and draw a line on
each side of the vertical stabilizer where it
meets the top of the fuselage.
!2) Slidethe vertical stabilizerinto the slot
in the top of the fuselage. The rear edge of
thestabilizer shouldbeflushwiththerearedge
of the fuselage and the lower rudder hinge
should engage the precut hinge slot in the
lowerfuselage. The bottom edgeof the stabi-
lizer should also be firmly pushed against the
top of the horizontal stabilizer.
! 4) With the stabilizer held firmly in place,
use a pen and draw lines onto the stabilizer
where it and the fuselage sides meet. Do this
on both the right and left sides and top and
bottom of the stabilizer.
! 5) Remove the stabilizer. Using the lines
youjust drew asa guide, carefullyremove the
covering from between them using a model-
ingknife.

alignedcorrectly,apply C/Aglueto the top and
bottom of the stabilizer mounting area and to
the stabilizer mounting platform sides.
