Ensure that it is impossible for any object to stall or block the propeller.
Every time you intend to operate your model check carefully that it and
everything attached to it (e.g. propeller, RC components etc.) is in good
condition and undamaged. If you find a fault, do not fly the model until you
have corrected it.
Satisfy yourself that your frequency 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.
After each flying session remove the battery from the model, check that it is
discharged, and store it in a safe place, well out of the reach of children, at a
temperature of around +5° to +25° C.
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.
