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 correctpartsand thatthey fitand are
alignedproperly beforegluing!This willassure
proper assembly. PIPER CUB 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.

calculated by how the weighted clunk should
restabout 8mmaway fromthe rearofthetank
andmove freelyinside thetank). Connectone
end of the line to the weighted clunk and the
other end to the nylon pick up tube in the

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.
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.
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

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.
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.
