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.
The operator of the model must be in full possession of his or her bodily and
mental faculties. As with car driving, operating a model aircraft under the
influence of alcohol or drugs is not permissible under any circumstances.
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.
Always keep a reasonable distance away from people and objects when flying;
never fly low over people's heads, and never fly 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 ext reme temperatures can lead
to changes in battery capacity and material characteristics, weakened glued
joints and other unwanted effects.
All model flyers should behave in a way that minimises the danger to people
and property. Never act in any manner which will disturb other flyers and
jeopardise safe, orderly flying at the site.
Never operate your model aircraft close to high-tension overhead cables,
industrial sites, residential areas, public roads, squares, school playgrounds,
public parks or sports grounds etc.
Pre-flight checks
Check that all the working systems are operating correctly before every flying
session: switch on the transmitter, followed by the receiver. Extend the
transmitter aerial fully, and check that all the control surfaces are exactly at
centre (neutral) when the sticks and trims are central. Ensure that the control
surfaces deflect in the correct direction. Repeat the check with the motor
running, while a friend holds the model firmly for you.
If you have not flown a model aircraft of this type before, we strongly
recommend that you ask an experienced modeller to check the aeroplane and
stand by your side during the first few flights.
Don't ignore our warnings. They refer to materials and situations which, if
ignored, can result in fatal injury or permanent damage.
Propellers and other rotating parts which are powered by a motor constitute a
permanent hazard and represent 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
cut your finger badly.
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.
