GRAUPNER IDX 248 Instructions De Montage page 28

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.
Never fly your model in protected sites, animal or plant sanctuaries or sites of special scientific interest
•
(SSSIs).
Never fly the model in adverse conditions, e.g. rain, storm or strong wind, or temperatures below -5° C or
•
above +35° C.
Before you fly the model check that the radio control system is working reliably, and that all connections are
•
firmly seated.
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.
The batteries must be given a full charge before the model is flown, and it is important to check the
•
effective range of the radio control system. It is particularly important that the transmitter should be fully
charged before each flying session.
Ensure that the frequency you intend to use is not already in use by other modellers. Never fly your model
•
if you are not certain that your channel is free. If there are other modellers in the vicinity, ask them
specifically which channels they are using.
Read and observe the instructions and recommendations supplied with your radio control system and
•
accessories.
Always disconnect the power system from the flight battery before carrying out any work on these
•
components.
When the drive battery is connected keep well clear of the area around the propeller, as this represents
•
the greatest risk of accident and injury. Make sure any spectators do the same.
Do not be tempted to exceed the recommended operating voltage. Higher voltages may cause the motor to
•
overheat, and the electrical cables may even melt. If this should happen, the model could easily be ruined
or even catch fire.
Ensure that all the power system components are free-moving.
•
Check that your servos are not mechanically obstructed at any point in their full travel.
•
Dry cells and rechargeable batteries must never be short-circuited, and must not come into direct contact
•
with water.
Allow the motor and speed controller to cool down after every flight. Take care not to touch the hot parts.
•
Remove the rechargeable battery if the model is to be transported, or will not be used for a long period.
•
Do not subject the model to high levels of humidity, heat, cold or dirt, and never leave it in a hot car in the
•
Summer.
Secure the model and your RC equipment carefully when transporting them. They may be seriously
•
damaged if they are free to slide about,.
If you have to recover the model after an out-landing, take care not to risk your own life or that of
•
others.
Care and maintenance
Clean the model carefully after every session.
•
Clean the model and the radio control components using suitable cleaning agents only. Ask your local
•
model shop if you are not sure.
Notes on building the model
Before you start construction it is essential to read right through these instructions, using the Parts List
•
constantly as a reference. In general terms the Building Instructions and the Parts List reflect the sequence
of assembly. Be sure to study the stage photos when building, as they are a valuable source of additional
information.
Bear in mind the possible hazards involved in the use of tools.
•
You will need a sanding block for cleaning up the edges of the pre-cut Depron parts, and for chamfering the
•
edges of hinged panels. Make this by sticking abrasive paper to a flat wooden block using double-sided
adhesive tape. 120-grit and 240-grit abrasives have proved ideal.
Deploy all cables neatly, wherever possible without crossing them over. It is of fundamental importance
•
never to allow a positive wire to make electrical contact with a negative wire. Deploy all motor cables in
such a way that there is no chance of them contacting any rotating parts of the power system. Use cable
ties or adhesive tape for this.
Deploy the receiver aerial as far from all high-current wires as possible (at least 3 cm).
•
Please ensure that the only materials to make contact with the Depron surfaces are foam-compatible
•
adhesives and cleaning agents, as other solvents may dissolve and destroy the surface.
Recommended adhesives for gluing various materials:
