Use only matching polarised electrical connectors. The flight battery, all cables and connectors
must be insulated carefully to prevent short-circuits, especially if you make them up yourself.
Never combine connectors with contacts of different materials, e.g. tin-plated and gold-plated,
as the connections will not be reliable in the long-term.
If you prefer to use a motor switch or speed controller with an integral receiver power supply
(BEC system), please use Graupner gold-contact connectors exclusively. Take great care to
avoid short-circuits and incorrect polarity.
The high energy density of Li-Po batteries involves a risk of fire and even explosion.
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.
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. Model flying needs to be
learned just like any other demanding skill.
As manufacturers we are not in a position to influence the way you build and operate your RC
model aircraft, and for this reason we deny all liability. All we can do is expressly point out the
hazards involved in this activity.
We suggest that you ask an experienced model flyer for help, or join a model club or flight
training school. Your local model shop and the specialist magazines are excellent sources of
information. If at all possible, it is always best to join a club and fly at the approved model
flying site.
You alone are responsible for the safe operation of your radio-controlled model. If you have
any questions regarding the safe operation of your RC model aeroplane, please turn to your
local model shop in the first instance, where the staff will be pleased to help you.
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.
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.
If there are passers-by or spectators at your flying site, make sure that they are aware of the
dangers inherent in your activity before you start the motor, and insist that they keep a safe
distance away - at least 5 m behind the rotational plane of the propeller.
Always keep a safe distance away from people and objects when flying; never fly low over
people’s heads, and never fly directly towards them.
Radio-controlled models should only be flown in “normal” weather conditions, i.e. a
temperature range of -5° to +35° C. More extreme temperature s can lead to changes in battery
capacity and material characteristics, weakened glued joints and other unwanted effects.
All model flyers should behave in a way that minimises the danger to people and property.
Never act in any manner which will disturb other flyers and jeopardise safe, orderly flying at
the site.
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.
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 slice off your finger.
