•
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 motors produce lethal carbon monoxide gas just
like full-size engines.
•
Motors 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.
•
Model fuels are volatile and highly inflammable. Keep them well away from
open flames, excessive heat, all possible sources of sparks and anything
else which could result in a fire. Do not smoke in the immediate vicinity of
fuel or fuel vapours.
•
Model engines generate a lot of heat. The motor and silencer in particular
become very hot when running, and stay at a high temperature for quite a
while. Touching the hot parts can give you serious burns, so take care
especially when carrying out adjustments - wear protective gloves. Hot
engines can even start a fire under certain circumstances.
•
When the motor is running it expels hot toxic gases from the exhaust
together with very hot fluid combustion residues which can burn you if you
are not careful.
•
Remove all unused fuel from the fueltank and motor after every session.
•
Every time you intend to operate your model check carefully that it and
everything attached to it (e.g. propeller, linkages, control surfaces etc.) is in
good condition and undamaged. If you find a fault, do not fly the model
until you have corrected it.
•
Model engines are usually started with the help of an electric starter which
should be fitted with the appropriate adaptor where necessary. With fixed-
wing models an alternative is to use a “chicken stick” - a length of thick
wooden dowel with a piece of water hose pushed over it.
•
Many model motors are very noisy, producing a sound level much higher
than 85 dB (A-weighted), which implies that you should wear ear defenders.
Never run a motor without the silencer fitted. Even with a silencer, model
engines can easily disturb your neighbours. Don’t run engines when other
people expect peace and quiet.
•
If you start your motor when the model is standing on loose or sandy
ground, the propeller will suck up sand and dust and hurl it around, and it
