If you are buying a radio control system for your new model, ensure that the
transmitter and receiving system are expressly stated to be suitable for use in
model aircraft, and bear the appropriate approval stickers.
The frequency bands used for the radio control of models are also employed by
other radio transmitting and RF equipment. For this reason it is not possible to be
completely sure that no interference will occur when you are flying your model.
You may need to pay a licence fee for using approved RC equipment to control a
model aircraft on the appropriate channels in the 35 MHz band; this depends on
the country in which you wish to fly the model.
Radio-controlled model aircraft are extremely demanding and potentially
dangerous objects, and require a high level of expertise, skill and responsibility
from the operator.
In legal terms our models are classed as aircraft, and as such are subject to legal
regulations and restrictions which must be observed at all times. Our brochure
“Modellflugrecht, Paragrafen und mehr” (Model Aviation Law, Legal Requirements
and more) is available under Order No. 8034.02, and contains a summary of all
these rules. Your local model shop should have a copy which you can read. There
are also Post Office regulations concerning your radio control system, and these
must be observed. 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.
Be sure to use matching polarised electrical connectors. All high-current cables,
connectors and the drive battery terminals must be insulated to prevent short-
circuits, especially if you attach the connectors yourself. Never combine different
types of connector, e.g. tin-plated and gold-plated contacts, as they cannot be
expected to work reliably in the long-term.
If you are using a BEC speed controller or switch (integral receiver power supply),
it must be fitted with Graupner gold-contact connectors.
Avoid short-circuits and reversed 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. Nobody would consider climbing into a light aircraft and - without training
- try to fly it. Model flying is just such a skill, and needs to be learned properly.
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
