ments and more) is available under Order No. 8034.02, and contains a summary 
of  all  these  rules;  your  local  model  shop  should  have  a  copy  which  you  can 
read. There are also Post Office regulations concerning your radio control sys-
tem,  and  these  must  be  observed.  Refer  to  your  RC  system  instructions  for 
more details. 
 
It  is  important  to  use  only  those  parts  included  in  the  kit,  together  with  other 
genuine  Graupner  accessories  and  replacement  parts  as  recommended  ex-
pressly  by  us.  Even  if  you  change  a  single  component,  you  can  no  longer  be 
sure that the whole system will work reliably, and such changes also invalidate 
your guarantee. 
Use only matching polarised connectors. 
Avoid short circuits and reverse polarity at all times. 
The high energy density of NiMH batteries involves a permanent risk of fire and 
even explosion. 
 
A radio-controlled model aircraft can only work properly and fulfil your expec-
tations  if  it  is  built  very  carefully  and  in  accordance with  the building  instruc-
tions. If you wish to avoid injuring people and damaging property, it is essen-
tial  to  be  careful  and  painstaking  at  all  stages  of  building  and  operating  your 
model.  Nobody  would  climb  into  a  full-size  sailplane  and  try  to  fly  it  without 
completing a course of training first. Model flying is just such a skill, and has 
to be learned in exactly the same way. 
However, as manufacturers we have no means of influencing the way you build 
and  operate  your  RC  model  aircraft,  and  for  this  reason  we  can  do  no  more 
than point out the hazards expressly. We accept no further liability. 
 
If you need help, please enlist the aid of an experienced modeller, join a model 
club or enrol at a model flying training school. Model shops and the specialist 
model press are also good sources of information. The best course is always 
to join a club and fly at the approved model flying site. 
 
Adhesives and paints contain solvents which may be hazardous to health un-
der certain circumstances. Read and observe the notes and warnings supplied 
by the manufacturer of these materials. 
 
The operator of the model must be in full possession of his or her bodily and 
mental faculties. As with car driving, flying a model aircraft under the influence 
of alcohol or drugs is highly dangerous and not permissible under any circum-
stances. 
 
Make sure that all passers-by and onlookers are aware of the hazards involved 
in the operation of your model. 
 
Keep  a  safe  distance  between  your  model  and  other  people  or  objects.  Never 
fly low over people or directly towards them. 
 
Radio-controlled models should only be flown in “normal” weather conditions, 
i.e. a temperature range of -5° to +35°C. More extreme temperatures can lead to
