1 HARDWARE PACK
1 Landing gear.....
Please trial  t all the parts. Make sure you have
the correct parts and that they  t and are aligned
properly before gluing! This will assure proper
assembly. THUNDERBIRDS 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.
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 aircraft and to
protect the table. Keep a couple of jars or bowls
handy to hold the small parts after you open the
bag.

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  lm more than is absolutely
necessary. If the air or the iron is too hot, the  lm 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 you
have to carry out is important and must be done
carefully. The model will only be strong and  y 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  t the screw.
Caution:
This model is not a toy!
If you are a beginner to this type of powered model,
please ask an experienced model  yer for 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 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  lm covering
Minor creases or bubbles may develop in the
 lm covering due to major  uctuations in weather
conditions (temperature, humidity etc.); in rare cases
you may even  nd a slight warp in a component.
These minor faults are in the nature of  lm-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.
+ This is not a toy
+ Be sure that no other  yers are using your radio
frequency.
+ Wear safety glasses.
+ The glow plug clip must be securely attached to
the glow plug.
+ Do not start the EDF if people are near.
