1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2)Removeeach hingefromthe 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
ofhingeis on eithersideof the hingelinewhen
the aileron is mounted to the aileron.
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
shouldbe maintainedbetween the wingpanel
andaileron.
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 youproperly adherethe
hingesin placeper thesteps thatfollow
using a high-quality thin C/A glue.
Note:
4)Deflect the aileron and completely
saturate each hinge with thin C/A glue. The
aileronsfrontsurface should lightlycontactthe
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 hinge is constructed of a special
material that allows the C/A to wick or
penetrateanddistribute throughoutthe
hinge, securely bonding it to the wood
structureof thewingpanel andaileron.
To avoid scratching your new aero-
plane we suggest that you cover your work-
benchwith anold towel. Keep a coupleof jars
orbowlshandytoholdthesmallpartsafteryou
open the bags.

HINGING THE ELEVATOR.
8)Afterbothailerons 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.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
HINGING THE RUDDER.
Glue the elevator hinges in place using the
same techniques used to hinge the ailerons.
Glue the rudder hinges in place using the
same techniques used to hinge the ailerons.
Work the aileron up and down several
times to “work in” the hinges and check
for proper movement.

2) Usinga modelingknife, cutone length
ofsilicon fuel line. Connectone endofthe line
tothe weightedfuel pickup and theother end
to the nylon pick up tube.(The silicon tube is
not included).
3) Carefully bend the second nylon tube
up at a 45º angle. This tube is the vent tube.
1) Using a modeling knife, carefully cut
off the rear portion of one of the 3 nylon tubes
leaving 1/2” protruding from the rear of the
stopper. This will be the fuel pick up tube.

4) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using a
modeling knife. If flashing is present, make
sure none falls into the tank.
5) With the stopper assembly in place,
the weighted pick-up should rest away from
therear of thetank and movefreely inside the
tank. The top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
Important: When the stopper assembly is in-
stalled in the tank, the top of the vent tube
should rest just below the top surface of the
tank. It should not touch the top of the tank.
Carefully use a lighter or heat gun to
permenently set the angle of the vent tube.
6) When satisfied with the alignment of
the stopper assembly tighten the 3 x 20mm
machine screw until the rubber stopper ex-
pands and seals the tank opening. Do not
overtighten the assembly as this could cause
the tank to split.
FUEL TANK INSTALLATION.
You should mark which tube is the vent
and which is the fuel pickup when you
attach fuel tubing to the tubes in the stopper.
Once the tank is installed inside the fuselage,
it may be difficult to determine which is which.

and fuel filler valve. Secure the cowl to fuse-
lage using the 3x10mm screws (4).
Becauseof the sizeof thecowl, it maybe nec-
essaryto usea needlevalve extensionfor the

1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
yourplane to losecontrol and crash. Thecen-
ter of gravity is locate 65mm back from the
leading edge of the wing, measured at wing
tip.
BALANCING.

5) If your radio transmitter is equipped
withdual rateswitches double checkthat they
are on the low rate setting for your first few
flights.
65mm.
Do not use the aerobatic settings for
initialtestflyingor sport flying.
 1) We highly recommend setting up the
CAP 232 using the control throws listed at
right. We have listed control throws for both
Low Rate (initial test flying/sport flying) and
High Rate (aerobatic flying).
 3) When the elevator, rudder and aileron
control surfaces are centered, use a ruler and
check the amount of the control throw in each
surface. The control throws should be
measured at the widest point of each sur-
face!
 2) Turnon the radio system, and with the
trim tabs on the transmitter in neutral, center
the control surfaces by making adjustments
totheclevises oradjustableservo connectors.
The servo arms should be centered also.
CONTROL THROWS.  F) From behind the airplane, look at the
ailerononthe rightwinghalf. Movethe aileron
sticktotheright. Therightaileronshouldmove
upand the otheraileron shouldmovedown. If
it does not, flip the servo reversing switch on
your transmitter to change the direction.
2) Check every bolt and every glue joint
in the CAP 232 to ensure that everything is
tight and well bonded.
PREFLIGHT CHECK.
1) Completely charge your transmitter
and receiver batteries before your first day of
flying.
3) Double check the balance of the air-
plane. Do this with the fuel tank empty.
4) Checkthe controlsurfaces. All should
move in the correct direction and not bind in
any way.
2) If the nose of the plane falls, the plane
is nose heavy. To correct this first move the
battery pack further back in the fuselage. If
this is not possible or does not correct it, stick
small amounts of lead weight on the fuselage
sides under the horizontal stabilizer. If the tail
of the plane falls, the plane is tail heavy.
To correct this, move the batteryand receiver
forward orif this is not possible, stick weight
ontothe firewall.Whenbalanced correctly,the
airplane should sit level or slightly nose down
when you lift it up with your fingers.
 E)Check thethrottle. Moving the throttle
stick forward should open the carburetor bar-
rel. Ifitdoesnot,flip the servo reversingswitch
on your transmitter to change the direction.
 D) Check the rudder. Looking from be-
hindthe airplane, movethe rudderstick to the
right. Therudder should moveto the right. Ifit
does not, flip the servo reversing switch on
your transmitter to change the direction.
FLIGHT PREPARATION.
 A) Check the operation and direction of
the elevator, rudder, ailerons and throttle.
 C) Check the elevator first. Pull back on
theelevator stick. Theelevator halvesshould
move up. If it they do not, flip the servo re-
versing switch on your transmitter to change
the direction.
 B) Plug in your radio system per the
manufacturer's instructions and turn every-
thingon.
 4) By moving the position of the adjust-
able control horn out from the control surface,
you will decrease the amount of throw of that
control surface. Moving the adjustable con-
trol horn toward the control surface will in-
crease the amount of throw.
