nt such as acetone. If you neglect this,
•
selves state the letters E, F, G, which indicate the ABS sheets containing particular
laser-cut parts.
•
If you have to salvage the model, take care not to risk your own life or that of others
.
•
Check regularly that the hull is completely watertight, as the model may sink if too much water enters
the hull. Check the boat for damage before every run, and ensure that water cannot penetrate the hull
through the shaft or rudder openings.
•
Take care to seal the model before every run, so that water cannot enter. Before running the boat,
seal the hatch cover completely by applying tape all round.
Care and maintenance
•
Clean the model carefully after every run, and remove any water which penetrates the hull. If water
gets into any of the RC components, dry them out and send them to your nearest GRAUPNER
Service Centre for checking.
•
Clean the model and RC components using suitable cleaning agents only. Ask your model shop for
information.
•
Lubricate the propeller shafts at regular intervals.
•
If the model is not to be operated for a considerable time, it is important to dismantle all the moving
parts (propeller shaft etc.), and clean and re-lubricate them.
Notes on building the model
•
Before you start building the boat, please take the time to study the plan and read right through the
instructions, referring to the Parts List constantly. In general terms the instructions and parts list
reflect the sequence of assembly.
•
Plan the installation of the RC components and the accessories for the auxiliary working systems
before you start building the model, as it will be more difficult or even impossible to install certain
parts when the model is complete.
•
Please bear in mind that many tools can be dangerous if misused or handled carelessly.
•
The vacuum-moulded parts are best cut out using scissors (our Lexan shears, Order No. 26, are
excellent for this). In many areas a sharp knife (e.g. Order No. 982) also works; simply cut along the
marked lines. It is always best to leave a little excess material, so that you can sand the parts back to
final size. Run a soft pencil along the marked lines to make them easier to see.
•
It is important to compare all the wooden parts with the drawings on the plan before gluing them in
place. This is necessary because some parts have to be prepared in some way beforehand, such as
chamfering particular edges.
•
The die-cut wooden parts can be separated from their sheets using a sharp balsa knife. If the cutter
has not penetrated right through the wood, use a fretsaw to cut along the stamped line. Sand all cut
edges to remove any rough areas.
•
The surfaces shown hatched-in are joint areas, i.e. other parts are glued at this point.
•
Before installing any wooden part, sand the surfaces smooth overall and apply several coats of
GLATTFIX sanding sealer (Order No. 207) to prevent the material absorbing water.
•
The electric motors must be suppressed by fitting a 470 nF capacitor (Order No. 3588): solder the
capacitor across the motor terminals to form a bridge. Fit two additional 47 nF capacitors (Order No.
3584) between the terminals and the motor case (see the wiring diagram on the plan).
•
Deploy all electrical cables neatly, without crossing them over. Take great care to avoid any bare
positive wire touching any negative wire.
•
Be sure to use cable which is capable of carrying the high currents which flow when the boat is
operating.
•
Deploy the receiver aerial as far away as possible from any high-current cables (at least 3 cm).
•
The shaft systems must be lubricated; be sure to use a type of grease or oil which does not soil or
contaminate water (e.g. Order No. 570).
Before gluing parts together, it is important to clean the joint surfaces carefully. This is best done by
sanding lightly, followed by wiping with a non-greasy liquid detergent or methylated spirit (“meths”).
The same applies to all surfaces which are to be painted, as this improves the paint’s adhesion
considerably. Before gluing any part to the hull it is essential to roughen the surface carefully using
fine abrasive paper, and de-grease it thoroughly using a solve
you cannot expect the glued joints to “hold” in the long-term.
