Leave the transmitter aerial collapsed, and walk away from the model. At a reasonable ground
range check that all the control surfaces still work perfectly when you move the sticks.
Repeat the check with the motor running, while a friend holds the model securely.
The first time you fly any new model aircraft we strongly recommend that you enlist the help of
an experienced modeller to help you check the model, and offer advice while you are flying.
Don't ignore our warnings. They refer to hazardous materials and processes which, if ignored,
can result in fatal injury or serious damage to property.
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 may
come loose and fly off at high speed, hitting you or anybody else in the vicinity. 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 propellers, gearboxes, 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 holding the model make sure that you are standing on a safe surface and
cannot slip. Wear shoes with high-grip soles, 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 (over 50ºC), faulty or damaged. Heed the instructions
provided by the battery manufacturer at all times.
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
