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.
Ensure that it is impossible for any object to stall or block the propeller.
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.
Every time you intend to operate your model check carefully that it and everything attached to
it (e.g. propeller, gearbox, RC components etc.) is in good condition and undamaged. If you
find a fault, do not fly the model until you have corrected it.
Whenever you are holding the model make sure that you are standing on a stable surface and
cannot slip. Wear shoes with high-grip soles, such as trainers.
Ask all the other model pilots at the flying site what frequencies they are using, and satisfy
yourself that your channel is vacant before you switch on. 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 another person might pick it up and try to use it.
Do not switch on the electric motor unless you are sure that there is nothing in the rotational
plane of the propeller. Never attempt to stop the spinning propeller. Electric motors with the
propeller attached should only be run when firmly mounted.
If you are to fly your model safely and avoid problems, it is essential that you are aware of its
position and attitude throughout each flight - so don’t let it fly too far away! If you detect a
control problem or interference during a flight, immediately land the model to prevent a
potential accident. Models must always give way to full-size aircraft. Take-off and landing
strips should be kept free of people and other obstacles.
Your RC system can only work reliably if the batteries are kept fully charged.
Never use batteries which are hot, faulty or damaged. At all times heed the instructions
provided by the battery manufacturer.
Before each flight check that all functions on the model aircraft are working correctly, and that
the radio control system is in good order and operating at full range. Note that the motor
control (throttle) function on the transmitter must always be moved to the OFF position as the
first stage in preparing for a flight. To avoid the danger of the electric motor bursting into life
unexpectedly, always switch on the transmitter first, and only then the receiving system. The
opposite applies at the end of a flight: always switch off the receiving system first, and finally
the transmitter.
Check that the control surfaces follow the movement of the transmitter sticks:
When you move the aileron stick to the right, the right aileron should deflect up, the left aileron
down.
Pull the elevator stick back towards you, and the elevator should deflect up.
Move the transmitter controls smoothly at all times; don’t jerk the sticks about abruptly when
the model is in the air.
Please don’t misunderstand the purpose of these notes. We only want to make you aware of
the many dangers and hazards which can arise if you work carelessly or irresponsibly. If you
take reasonable care, model flying is a highly creative, instructive, enjoyable and relaxing
pastime.
