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.

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 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 wrap: 

Hold the panel twisted gently in

                          the  opposite  direction  to  the  wrap,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 

+   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 propel-

ler. 

 +  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.
