To avoid scratching your new airplane, do
not 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.
Please trial fit all the parts. Make sure you
havethe correctpartsandthatthey fitand are
alignedproperly beforegluing!This willassure
properassembly. SPEEDAIR-40ARFis 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
kitarefuelproof.However,theyarenottolerant
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.

1) The stopper has been pre-assembled
at the factory.
2) Using a modeling knife, cut one length of
siliconfuel line (thelength ofsilicon fuelline is
calculated by how the weighted clunk should
restabout 8mmaway fromthe rearof thetank
andmove freelyinside thetank). Connectone
end of the line to the weighted clunk and the

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.

a 45 degree angle (using a cigarette lighter).
This tubewill bevent tubetothefuelingvalve.

5) 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 of it falls into the 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.
Vent tube Fuel pick- up tube
Fuelfilltube
6) When satisfied with the alignment of the
stopper assembly tighten the 3mm x 20mm
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.
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, whereitexitsthefuselage behindthe
enginemountingbox andto therearofthe tank
at the forward bulkhead.
Do not secure the tank into place perma-
nently until after balancing the airplane.
You may need to remove the tank to mount
the battery in the fuel tank compartment.

partmentandthrough thepre-drilledholein the

gine,whileguidingthefueltankintoplace.Push
the fuel tank as far forward as possible, the

covering from between them using a model-
ingknife.
3. 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.
The top of the stabilizer does not have
the hinge pins exposed.

of 30 Minute Epoxy. Apply a thin layer to the
topand bottomofthe 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.

7) After the epoxy has fully cured, remove
the masking tape or T-pins used to hold the

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
rubbingalcohol.

move the covering that overlaps the stabilizer
mounting platform sides in the fuselage. Re-
move the covering from both the top and the
