suggest  that  you  ask  for  help  from  an  experienced  model  flyer,  or  join  a 
model  club  or  flight  training  school.  Your  local  model  shop  and  the 
specialist magazines are excellent sources of information. 

 

It is fundamentally essential to set the Centre of Gravity (C.G.) and control 
surface travels correctly. Adjust the model until they are exactly correct. 

 

Radio control system: satisfy yourself that your frequency is vacant before 
you  switch  on.  Check  your  RC  system  regularly  as  its  components 
eventually  wear  and  need  to  be  replaced  or  repaired.  Radio  interference 
caused by unknown sources can occur at any time without warning. If this 
should  happen,  your  model  will  be  uncontrollable  and  completely 
unpredictable.  Never  leave  your  radio  control  system  unguarded,  as  other 
people  might  pick  it  up  and  try  to  use  it.  Your  RC  system  can  only  work 
reliably if the batteries are kept fully charged. 

 

Don’t ignore our warnings. They refer to materials and situations which, if 
ignored, can result in fatal injury or permanent damage. 

 

You  alone  are  responsible  for  the  safe  operation  of  your  radio-controlled 
model aircraft and engine. 

 

If  you  have  any  questions  regarding  the  safe  operation  of  your  RC  model 
aircraft,  please  turn  to  your  local  model  shop  in  the  first  instance  as  the 
staff will be pleased to help you. 

 

Propellers  and  other  rotating  parts  which  are  powered  by  an  engine 
represent a permanent hazard and present a real risk of injury. Don’t touch 
them with any part of your body. For example, a propeller spinning at high 
speed can easily slice off a finger. 

 

Keep  well  clear  of  the  rotational  plane  of  the  propeller.  You  never  know 
when  some  part  may  come  loose  and  fly  off  at  high  speed,  hitting  you  or 
anybody  else  in  the  vicinity.  Never  touch  the  revolving  propeller  with  any 
object. 

 

Take  care  with  loose  clothing  such  as  scarves,  loose  shirts  etc.  Flapping 
cloth  can  easily  be  sucked  into  the  area  of  the  propeller  and  then  get 
tangled in the blades. This is extremely dangerous. 

 

If there are passers-by or spectators at your flying site, make sure that they 
are aware of the dangers inherent in your activity, and insist that they keep 
a safe distance away (at least 5 m). 

 

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  changes  in  battery  capacity,  material 
characteristics and other unwanted effects. 

 

Model  fuels  are  toxic;  do  not  allow  them  to  come  into  contact  with  your 
eyes or mouth. Fuel should always be stored in clearly marked containers, 
out of the reach of children. 

 

Never  run  an  internal  combustion  engine  in  an  enclosed  space  such  as  a 
cellar, garage etc. Model engines produce lethal carbon monoxide gas just 
like full-size engines. 

 

Engines should only be run in the open air! 

 

Adhesives  and  paints  contain  solvents which  may  be  hazardous  to  health 
under  certain  circumstances.  Read  and  observe  the  notes  and  warnings 
supplied by the manufacturer of these materials.
