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 air-
craftand toprotect thetable.Keepacoupleof
jars or bowls handy to hold the small parts af-
ter you open the bag.
Pleasetrialfitalltheparts. Makesureyouhave
the correct parts and that they fit and are
alignedproperly beforegluing!Thiswillassure
proper assembly. EAGLE ARF is hand made
from natural materials, every plane is unique
andminor adjustmentsmayhave tobe 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 follow-
ing:paintthinner,C/Aglueaccelerator,C/Aglue
debonderandacetone. Donotletthesechemi-

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.
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.
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 ex-
pandsand sealsthetank opening.Do notover
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.
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.
