This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your PIPER CUB. 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
and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
proceduresdesignedtohelpthenew pilotonhiswaytosuccessfulR/C flight.Theywillalso beable
to advise on any insurance and safety regulations that may apply.

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. 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 su-
perior 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.

Caution: this model is not a toy!
If you are a beginner to this type of powered
model,please askan experiencedmodelflyer
forhelp andsupport.Ifyouattempttooperate
themodel withoutknowingwhat youaredoing
you could easily injure yourself or somebody
else. Please keep your safety and well-being
in mind at all times.
Important: before you start construction
Evenifyou havealready built alarge number
ofRC modelspleaseread rightthrough these
instructions and check all the kit components
against the parts list. We have taken great
trouble to keep construction as simple as
possible, without making any compromises
in the area of safety.
Note regarding the film covering
Minor creases or bubbles may develop in the
film covering due to major fluctuations in
weather conditions (temperature, humidity
etc.); in rare cases you may even find a slight
warp in a component. These minor faults are
in the nature of film-covered built-up wooden
structures, and can easily be corrected using
a heat gun, as commonly used for modelling.
Creases: Blowwarm airoverthearea
and rub down with a soft
cloth.
Wing warp: Hold the panel twisted
gently in the opposite
direction to the warp, and
apply warm air to remove
the creases from the
covering.
Caution! do not heat the film more than is
absolutely necessary. If the air or the iron is
too hot, the film may melt and holes may be
formed.
This model is highly pre-fabricated and can
bebuilt inavery shorttime.However,the work
which you have to carry out is important and
must be done carefully. The model will only
be strong and fly well if you complete your
tasks competently - so please work slowly
and accurately.
When self-tapping screws have to be
screwed into wood, apply a little white
glue to prevent them shaking loose: just
squirt white glue into the hole and fit the
screw.
+ This is not a toy
+ Be sure that no other flyers are using your
radio frequency.
+ Do not smoke near fuel
+ Store fuel in a cool, dry place, away from
children and pets.
+ Wear safety glasses.
+Theglowplug clipmustbesecurely attached
to the glow plug.
+ Do not flip the propeller with your fingers.
+ Keep loose clothing and wires away from
thepropeller.
+ Do not start the engine if people are near.
Donot standinlinewiththesideof thepropel-
ler.
+ Make engine adjustments from behind the
propeller only. Do not reach around the spin-
ningpropeller.

ata 45degreeangle (usingacigarettelighter).
This tubewill bevent tubeto thefuelingvalve.
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.
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.
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.
 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.
 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.

When cutting through the covering to
remove it, cut with only enough pressure
to only cut through the covering it’s self.
Cutting into the balsa structure may
weaken it. This could lead to possible fail-
ure during flight.
