This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your EXCEL 2000. Use the parts listing below to
identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is
capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
IfyouareinexperiencedwithbasicR/CflightwestronglyrecommendyoucontactyourR/Csupplier

Toavoid scratching yournew airplane,donot
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old
towel or brown paper, both to protect the
aircraftand toprotect thetable. Keepa couple
of jars or bowls handy to hold the small parts
after you open the bag.
Pleasetrialfitalltheparts. Makesureyouhave
the correct parts and that they fit and are
alignedproperly beforegluing!Thiswillassure
proper assembly.EXCEL 2000 ARF is hand
made from natural materials, every plane is
unique and minor adjustments may have to
be made. However, you should find the fit
superior and assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

+ This is not a toy
+ Be sure that no other flyers are using your
radio frequency.
+ Wear safety glasses.
+ Keep loose clothing and wires away from
thepropeller.
+ Do not start the engine if people are near.
Do not stand in line with the side of the
propeller.
+ Make engine adjustments from behind the
propeller only. Do not reach around the
spinningpropeller.
SAFETY PRECAUTION.
 1) Install the rubber grommets and brass
eyelets onto the aileron servo.
Because the size of servos differ, you
mayneed toadjustthe sizeofthe precutopen-
inginthe mount. Thenotch inthesides ofthe
mount allow the servo lead to pass through.

5) Using Kwik Bond 5 Minute Epoxy, glue
the servo mount into place. Remove any ex-
cess epoxy using a paper towel and rubbing
alcohol. Use pieces of masking tape to hold
the tray in place until the epoxy fully cures.
2) Place the mount onto the wing haft,
aligning the cutout in the mount with the cut-
out in the wing. The two notches in the mount
should face the leading edge of the wing.
 3) While holding the servo mount firmly in
place, trace around it using a pen.
4) Remove the mount, and using a model-
ing knife, carefully remove the covering from
inside the outline you drew.

 7) Install the aileron servo into the servo
mount, withthe outputshaft towardsthe lead-
ing edge of the wing, using the wood screws
provided with your radio system. Drill 1/16”
pilotholesthrough themount beforeinstalling
the screws. This will prevent the wood from
splitting.

use 220 grit sandpaper with a sanding block
and sand down the edges and ends of the
brace until it fits properly.

INSTALLING THE STOPPER ASSEMBLY
1) The stopper has been pre-assembled
at the factory.
2) Using a modeling knife, cut one length
ofsilicon fuelline(thelengthofsiliconfuel line
iscalculatedbyhowtheweightedclunkshould
restabout 8mmaway fromtherearofthetank
andmove freelyinside thetank). Connectone
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the
stopper.
3) Carefully bend the second nylon tube
up at a 45 degree angle (using a cigarette
lighter). This tube will be the vent tube to the
muffler.

This tubewill bevent tubeto thefuelingvalve.
FUEL TANK.
When the stopper assembly is installed
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.

Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
througheasily.
9) To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
thetank, whereit exitsthefuselage behindthe
enginemountingbox andtotherearofthetank
at the forward bulkhead.
Do not secure the tank into place
permanently until after balancing the
airplane. You may need to remove the tank
to mount the battery in the fuel tank
compartment.
8) Feed three lines through the fuel tank
compartment and through the pre-drilled hole
in the firewall. Pull the lines out from behind
the engine, while guiding the fuel tank into
place. Push the fuel tank as far forward as
possible,the frontofthetankshould justabout
touch the back of the firewall.
6) When satisfied with the alignment of
thestopperassemblytightenthe3mmx20mm
machine screw until the rubber stopper
expands and seals the tank opening. Do not
over tighten the assembly as this could cause
the tank to split.
7) Using a modeling knife, cut 3 lengths of
fuel line 150mm long. Connect 2 lines to the 2
vent tubes and 1 line to the fuel pickup tube in
the stopper.
Fueltank.
5) Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodeling knife. Ifflashing is present, make
sure none of it falls into the tank.
Locate the long piece of wire used for the
throttlepushrod. Oneendofthewire hasbeen
pre-bend in to a “Z” bend at the factory. This
“Z” bend should be inserted into the throttle

aligned correctly, mix up a generous amount
of 30 Minute Epoxy. Apply a thin layer to the
topandbottomofthe stabilizermounting plat-
form sides in the fuselage. Slide the stabilizer
in place and realign. Double check all of your
mea-surements once more before the epoxy
cures. Hold the stabilizer in place with T-pins
or masking tape and remove any excess ep-
oxy using a paper towel and rubbing alcohol.
When cutting through the covering to re-
move it, cut with only enough pressure to
only cut through the covering itself. Cut-
ting into the balsa structure may weaken
it.

joints. Use more epoxy to fill in any gaps that
may exist that were not filled previously and
clean up the excess using a paper towel and

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.
 1) Slide thevertical stabilizerinto theslot
in the top of the fuselage. The bottom edge of
the stabilizer should also be firmly pushed
against the top of the horizontal stabilizer.
 3) Remove the vertical stabilizer. Using
a modeling knife, remove the covering from
below the lines you drew. Also remove the
covering from the bottom edge of the stabi-
lizer and the bottom and top edges of the filler
block. Leavethecovering inplaceonthesides

When cutting through the covering to re-
moveit,cut withonlyenough pressureto only
cut through the covering itself. Cutting into
the balsa structure may weaken it.
