Instruction Manual

Caution:

 this model is not a toy!
If you are a beginner to this type of powered model, please ask an experienced model flyer 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 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
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.

            SAFETY PRECAUTION.

 + This is not a toy

 + Be sure that no other flyers 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.
