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.
•
Don’t operate your aircraft from public roads, squares, school playgrounds,
public parks or sports grounds etc., and ensure that you are always in full
control of the model.
•
It is important that you are able to stop your engine at any time. This is
achieved by adjusting the throttle so that the barrel closes completely when
you move the throttle stick and trim to their end-points. If this does not work,
pinch the fuel feed line between your fingers or pull it off the carburettor.
Never try to stop the motor by grasping the flywheel, propeller or spinner!
•
All model flyers should behave in a manner which minimises the danger to
people and property. Never act in any way which will disturb other flyers and
jeopardise safe, orderly flying at the site.
•
In legal terms our models are classed as aircraft, and as such are subject to
legal regulations and restrictions which must be observed.
