Toavoidscratching yournewairplane, 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 air-
craftandto protect the table. Keepacouple of
jars or bowls handy to hold the small parts af-
ter you open the bag.
Pleasetrialfitall theparts.Makesureyouhave
the correct parts and that they fit and are

proper assembly.AVENSIS ARF is hand made
from natural materials, every plane is unique
andminoradjustments may have 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-

AVENSIS - Item code: BH137. Instruction Manual
Caution: this model is not a toy!
Ifyou are abeginner to this type of powered model, please ask an experienced model flyerfor help
and support. If you attempt to operate the model without knowing what you are doing 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
Even if you have already built a large number of RC models please read right through 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: Blow warm air over the area 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 be built in a very short time. However, the work which
youhave to carryout is important and must be done carefully.The model will only be strongand 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.
+ The glow plug clip must be securely attached to the glow plug.
+ Do not flip the propeller with your fingers.
+ Keep loose clothing and wires away from the propeller.
+ 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 spinning
propeller.

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,thefrontofthetankshouldjustabout

9. To secure the fuel tank in place, apply a
bead of silicon sealer to the forward area of
thetank,whereitexitsthefuselagebehindthe
enginemountingbox andtotherearofthe tank
at the forward bulkhead.
Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow
througheasily.
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.
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.
5. Test fit the stopper assembly into the
tank. It may be necessary to remove some of
the flashing around the tank opening using
amodelingknife. Ifflashing is present, make
sure none of it falls into the tank.
