•
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), 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
could easily get in your eyes and do damage. Wear protective goggles at
such times.
•
Take care that the glowplug clip and the glow lead cannot get tangled in the
propeller or other rotating parts. Check the throttle linkage too.
•
Take particular care when carrying the model with the motor running. Hold
the rotating parts well away from you!
•
Be sure to keep an adequate supply of fuel in the tank. Don’t continue to fly
the model until the tank is drained dry.
•
Never fly directly over people.
•
Never fly directly towards people.
•
Keep a safe distance from residential areas: at least 1.5 km “as the crow
flies”. The best solution is to join a model flying club and use the approved
flying site. Always keep well clear of high-tension overhead cables.
•
Whenever you are working on the motor, make sure that you are on a safe
surface and cannot slip. Get used to holding the model really securely.
•
Take-off and landing strips should be kept free of unauthorised people and
movable obstacles, particularly when a model is using the strip.
•
Watch the aeroplane constantly while it is in the air. Models must always
give way to full-size aircraft.
