GRAUPNER BO 209 MONSUN Bauanleitung Seite 15

Office regulations concerning your radio control system, and these must be observed at all
times. Refer to your RC system instructions for more details.
Be sure to use only those parts included in the kit, together with other genuine Graupner
accessories and replacement parts as recommended expressly by us. Even if you change a
single component you can no longer be sure that the system will work reliably, and such
changes also invalidate your guarantee.
It is important to use matching polarised connectors exclusively. All high-current cables,
connectors and flight batteries must be insulated carefully to avoid short-circuits, especially if
you assemble them yourself. Never combine connectors made of different materials, e.g. tin-
plated and gold-contact types, as they may not work reliably.
If you use a flight switch or speed controller with integral receiver power supply (BEC), use
only those types fitted with Graupner gold-contact connectors.
Avoid short circuits and reverse polarity at all times.
The high energy density of rechargeable batteries involves a permanent danger 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. Nobody would climb into a full-size sailplane and try to fly
it without completing a course of training first. Model flying is just such a skill, and has to be
learned in just the same way.
However, as manufacturers we have no means of influencing the way you build and operate
your RC model aircraft, and for this reason we can do no more than point out the hazards
expressly. We accept no further liability.
If you need help, please enlist the aid of an experienced modeller, join a model club or enrol at
a model flying training school. Model shops and the specialist model press are also good
sources of information. The best course is always to join a club and fly at the approved model
flying site.
Adhesives contain solvents which may be hazardous to health under certain circumstances.
Read and observe the notes and warnings supplied by the manufacturers of these materials.
The operator of the model must be in full possession of his bodily and mental faculties. As with
car driving, operating a model aircraft under the influence of alcohol or drugs is highly
dangerous and not permissible under any circumstances.
Make sure that all passers-by and onlookers are aware of the hazards involved in the operation
of your model. Remind them to keep a safe distance from the model: at least 5 m behind the
plane of the propeller.
Keep a safe distance between your model and other people or objects. Never fly low over
people or 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 temperatures can lead to changes in battery
capacity, material characteristics, the strength of glued joints and other unwanted effects.
All model flyers should behave in such a way that the danger to people and property is
minimised. Never act in any way which will disturb other pilots, or prevent safe, orderly flying
at the site.
Don't operate your model in the vicinity of overhead power cables, industrial sites, residential
areas, public roads, squares, school playgrounds, public parks or sports fields etc.
Pre-flight checks
Before every flight be sure to carry out a range check, and ensure that all functions are
working correctly. This is the procedure: switch on the transmitter, followed by the receiver.
