!4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfront surfaceshould lightlycontact the
wing during this procedure. Ideally, when the
hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the
aileron to the wing panel hinge line.
Note:
The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperativethatyou properlyadhere the
hingesinplace perthesteps thatfollow
using a high-quality thin C/A glue.
!1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
!2)Removeeach hingefrom the wingpanel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the aileron
untiltheT-pinis snugagainstthe aileron.This
will help ensure an equal amount of hinge is
oneither sideofthe hingelinewhentheaileron
is mounted to the wing panel.
HINGING THE AILERONS.
Note:
The hinge is constructed of a special
material that allows the C/A to wick or
penetrateand distributethroughout the
hinge, securely bonding it to the wood
structureofthe wingpanel andaileron.
!7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
!3) Slide the aileron on the wing panel 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 betweenthe wingpanel
andaileron.
!5) Turn the wing panel over and deflect the
aileron in the opposite direction from the
opposite side. Apply thin C/A glue to each
hinge,makingsurethattheC/Apenetratesinto
both the aileron and wing panel.
!6) Using C/A remover/debonder and a
papertowel,removeanyexcess C/Aglue that
may have accumulated on the wing or in the
aileronhingearea.

!8)After both 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.
Note:Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.
!1) Carefully remove the elevator from one
of the horizontal stabilizer panels. Note the
position of the hinges.
!2) Remove each hinge from the horizontal
stabilizerpanelandelevator andplace aT-pin
in the center of each hinge. Slide each hinge
intotheelevator untiltheT-pin is snugagainst
the elevator. This will help ensure an equal
amount of hinge is on either side of the hinge
line when the elevator is mounted to the
horizontal stabilizer panel.

stabilizer panel hinge line.
Note: The hinge is constructed of a special
material that allows the C/A to wick or

hinge, securely bonding it to the wood
structure of the horizontal stabilizer
panel and elevator.
!5) Turn the horizontal stabilizer panel over
and deflect the elevator in the opposite
directionfrom theoppositeside.Apply thinCA
glue to each hinge, making sure that the C/A
penetratesintoboththeelevatorand horizontal
stabilizer panel.
HINGING THE ELEVATORS.
!3) Slide the elevator on the horizontal
stabilizer panel until there is only a slight gap.
The hinge is now centered on the horizontal
stabilizer panel and elevator. Remove the T-
pins and snug the elevator against the
horizontal stabilizer panel. A gap of 1/64” or
less should be maintained between the
horizontal stabilizer panel and elevator.
!4)Deflect the elevator and completely
saturate each hinge with thin C/A glue. The
elevators front surface should lightly contact
thehorizontalstabilizer duringthis procedure.

!4)Deflect the rudder and completely
saturate each hinge with thin C/A glue. The
rudder front surface should lightly contact the
verticalfin duringthis procedure.Ideally, when
the hinges are glued in place, a 1/64” gap or
less will be maintained throughout the lengh
of the rudder to the fuselage panel hinge line.
!1) Carefully remove the rudder from the
vertical fin. Note the position of the hinges.
!2) Placing a T-pin in the center of each
hinge. Slide each hinge into the rudder until
the T-pin is snug against the rudder. This will
help ensure an equal amount of hinge is on
eithersideof thehinge linewhenthe rudderis
mounted to the fuselage panel.
Note:
!3) Slide the rudder on the vertical fin until
there is only a slight gap. The hinge is now
centered on the fuselage panel and rudder.
Remove the T-pins and snug the rudder
against the fuselage panel. A gap of 1/64” or
lessshouldbemaintainedbetween thevertical
fin panel and rudder.
!5)Turntheverticalfinpaneloveranddeflect

Because the size of servos differ, you
may need to adjust the size of the precut
opening in the mount. The notch in the
sides of the mount allow the servo lead to
pass through.
Install the rubber grommets and brass

!4) Carefully heat the vent tube using a
heat gun or lighter to permanently set the
angle of the tube.
When the stopper assembly is installed in
the tank, the top of the vent tube should rest
justbelow thetop surfaceofthetank. Itshould
not touch the top of the tank.

You should mark which tube is the
vent and which is the fuel pick up when
you attach fuel tubing to the tubes in the
stopper. Once the tank is installed inside
thefuselage, itmaybe difficulttodetermine
which is which.
INSTALLING THROTTLE SERVOS.
!6) With the stopper assembly in place,
the weighted pick up should rest about 3/8”
awayfrom therear ofthe tankandmovefreely

rest just below the top of the tank. It should
not touch the top of the tank.

pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
Because the size of servos differ, you
may need to adjust the size of the
precut opening in the mount. The notch
in the sides of the mount allow the servo

need to remove the throttle arm from the car-
buretor to be able to attach the Z-bend. When
complete, reattach the throttle arm to the car-

Because of the diameter of the na-
celle, it may be necessary to use a needle
valve extension for the high speed needle
valve. Make this out of sufficient length
1.5mm wire and install it into the end of
the needle valve. Secure the wire in place
by tightening the set screw in the side of
the needle valve.
! 2) While keeping the back edge of the
nacelle flush with the marks, align the front of
the nacelle with the crankshaft of the engine.
The front of the nacelle should be positioned
so the crankshaft is in nearly the middle of

VERTICAL STABILIZER INSTALLATION.
!1) Slidethevertical stabilizerinto the slot
of the fuselage. The bottom edge of the stabi-
lizer should also be firmly pushed against the
top of the horizontal stabilizer.
!2) 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.
!3) Remove the stabilizer. Using a mod-
eling knife, remove the covering from below
the lines you drew. Also remove the covering
from the bottom edge of the stabilizer and the
bottomand topedges ofthe fillerblock. Leave
the covering in place on the sides of the filler
block.
When cutting through the covering to
remove it, cut with only enough pressure
toonly cutthrough thecovering itself. Cut-
ting into the balsa structure may weaken
it.
