Never operate your model aircraft close to high-tension overhead cables, industrial sites,
residential areas, public roads, squares, school playgrounds, public parks or sports grounds
etc.
Pre-flight checks
Check all the model’s working systems before every flight: switch on the transmitter followed
by the receiving system, extend or deploy the transmitter aerial correctly, then check that all
the model’s control surfaces are at neutral (centre). Check the control surface travels, and that
they respond in the correct “sense” to transmitter commands. Repeat the check with the motor
running, while a friend holds the model securely for you.
If you are a relative beginner to model flying, we strongly recommend that you ask an
experienced modeller to support and help you during the first few flights.
Don’t ignore our warnings. They refer to materials and situations which, if ignored, can result
in fatal injury or permanent damage.
Propellers and other rotating parts which are powered by a motor constitute a permanent
hazard and represent a real risk of injury. Don’t touch them with any part of your body. For
example, a propeller spinning at high speed can easily cut your finger badly.
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; this can easily
result in serious personal injury. Ensure that no other object can come into contact with the
revolving propeller.
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, 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.
Before you switch the radio system on. always satisfy yourself that your frequency is vacant.
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 the transmitter on first, and only then the
receiving system. The opposite applies at the end of a flight: always switch the receiving
system off first, and finally the transmitter.
