•
Be sure to read right through the instructions covering assembly and operation of your model before
you attempt to operate it for the first time.
•
These safety notes are an integral part of the instructions. Please keep them and the operating
instructions in a safe place. If you ever dispose of the model be sure to pass them on to the new owner.
•
Powered model aircraft are very demanding and potentially dangerous machines, and call for a high
level of technical knowledge and skill from the operator, together with a responsible attitude.
•
Powered model aircraft are not suitable for young persons under 18 years of age.
•
Young people should only be permitted to operate this model under the instruction and supervision of
an adult who is aware of the hazards involved in this activity.
•
The operator of the model must be in full possession of his or her bodily and mental faculties. As with
car driving, operating a model aircraft under the influence of alcohol or drugs is not permissible under
any circumstances.
•
Radio-controlled model aircraft may only be employed for the purpose intended by the manufacturer.
They must never be used as man-carrying machines. We do not condone this model’s use in any way
except as a model aircraft.
•
A radio-controlled model aircraft can only work properly and fulfil your expectations if it is built very
carefully and in accordance with the building instructions. Do not make any modifications of any kind to
the design features or materials. If you wish to avoid injuring people and damaging property it is
essential to be careful and painstaking at all stages of building and operating your model. Nobody would
climb into a full-size light aircraft and try to fly it without completing a course of training first. Model
flying is a skill which has to be learned in just the same way. We suggest that you ask for help from an
experienced model flyer, or join a model club or flight training school. Your local model shop and the
specialist magazines are excellent sources of information.
•
It is fundamentally essential to set the Centre of Gravity (CG) and control surface travels correctly.
Adjust the model until they are exactly correct.
•
Radio control system: satisfy yourself that your frequency is vacant before you switch on. Check your
RC system regularly as its components eventually wear and need to be replaced or repaired. 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. Your RC system can only work reliably if
the batteries are kept fully charged.
•
Don’t ignore our warnings. They refer to materials and situations which, if ignored, can result in fatal
injury or permanent damage.
•
You alone are responsible for the safe operation of your radio-controlled model and motor.
•
If you have any questions regarding the safe operation of your RC model aircraft, please turn to your
local model shop in the first instance as the staff will be pleased to help you.
•
Propellers and other rotating parts which are powered by an engine 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 slice off a finger.
•
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.
•
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 there are passers-by or spectators at your flying site, make sure that they are aware of the dangers
inherent in your activity, and insist that they keep a safe distance away (at least 5 m).
•
Radio-controlled models should only be flown in “normal” weather conditions, i.e. a temperature range of
-5° to +35° C. More extreme temperatures can lead to changes in battery capacity, material characteristics
and other unwanted effects.
•
Model fuels are toxic; do not allow them to come into contact with your eyes or mouth. Fuel should
always be stored in clearly marked containers, out of the reach of children.
•
Never run an internal combustion engine in an enclosed space such as a cellar, garage etc. Model motors
produce lethal carbon monoxide gas just like full-size engines.
•
Engines should only be run in the open air!
•
Adhesives and paints contain solvents which may be hazardous to health under certain circumstances.
Read and observe the notes and warnings supplied by the manufacturer of these materials.
•
Model fuels are volatile and highly inflammable. Keep them well away from open flames, excessive heat,
all possible sources of sparks and anything else which could result in a fire. Do not smoke in the
immediate vicinity of fuel or fuel vapours.
•
Model engines generate a lot of heat. The motor and silencer in particular become very hot when running,
and stay at a high temperature for quite a while. Touching the hot parts can give you serious burns, so
take care especially when carrying out adjustments - wear protective gloves. Hot engines can even start a
fire under certain circumstances.
•
When the motor is running it expels hot toxic gases from the exhaust together with very hot fluid
combustion residues which can burn you if you are not careful.
•
Remove all unused fuel from the fueltank and engine after every session.
