Propellers and other rotating parts which are powered by a motor represent a permanent hazard and
present 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 quite badly.
Keep well clear of the rotational plane of the propeller. You never know when some part (or the whole
propeller) may come loose and fly off at high speed, hitting you or anybody else in the vicinity; this
can result in serious injuries. Never touch the revolving propeller with any object.
Ensure that there is no chance of any object obstructing the propeller and preventing it turning.
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.
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.
Every time you intend flying the model, check carefully that all parts connected to it are working
correctly, including propeller, gearbox, RC components, etc. Everything must be properly located
and firmly secured. Check for possible damage, and do not fly your model unless you are confident
that everything is in perfect order.
Whenever you are working on the motor, make sure that you are on a safe surface and cannot slip.
Wear high-grip shoes such as trainers.
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
other people might pick it up and try to use it.
Do not switch on an electric motor unless you are sure that there is nothing in the rotational plane of
the propeller. Don’t attempt to stop the spinning propeller with your hands. Never run an electric
motor with a propeller fitted unless it is firmly anchored.
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 (above 50°C), faulty or damaged. Always heed the instructions
provided by the battery manufacturer.
Before every flight be sure to carry out a range check, and ensure that all functions are working
correctly.
Note in particular that the motor control function on the transmitter must first be set to the OFF
position before you switch on the system. Always switch on the transmitter first, then the receiving
system, to eliminate any chance that the motor will burst into life unexpectedly. When switching off,
reverse the order: receiving system first, then the transmitter.
Check that the control surfaces move in the direction which corresponds to the stick movement.
After each session remove the battery from the model and store it in a discharged state at a
temperature of about +5° to +25°C. Batteries should be kept out of the reach of children at all times.
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 lack knowledge and experience, or work carelessly
or irresponsibly. If you take reasonable care model flying is a highly creative, instructive, enjoyable
and relaxing pastime.
