Before you run the model check that the radio control system is working reliably, and that all connections
are secure.
If dry cells are to be used as power supply, remember that they must never be recharged. Only batteries
marked specifically as ‘rechargeable’ can safely be recharged.
It is important to check the effective range of the radio control system before each session: switch on the
transmitter and receiving system, ask a friend to hold the transmitter, and walk about 100 m away, holding
the model. Your assistant should operate the controls constantly, and the model must respond reliably.
Check whether the channel you wish to use is not already occupied. Never switch the system on if you are
not sure whether “your” channel is already in use.
Note that other transmitters and radio equipment are capable of causing serious interference to your model.
If possible, ensure that no equipment of this type is in use in the vicinity while you are operating your
model.
Never work on the model’s power system unless the drive battery is isolated from the system.
When the drive battery is connected, make sure that you and everybody else
always
keep clear of the area
around the propeller, as this represents a serious injury risk.
Do not exceed the recommended operating voltage. Higher voltages may cause the motor and / or the
speed controller to overheat, and the electrical wiring could even melt. If this should happen, a fire could
start, in which case the model would be wrecked.
Check that all the drive train components work smoothly and freely. This applies in particular when you are
running the model, as leaves and other detritus can get caught up in the power train. If this happens, the
motor, the speed controller and / or the rudder servo may be ruined due to overloading.
Before running the model check that the sheets are free-moving, and have not become tangled or caught
up on the model.
Dry cells and rechargeable batteries must never be short-circuited. Do not allow them to come into direct
contact with water.
Remove the drive battery and any dry cells from the boat and the transmitter before storing the model.
Do not subject the boat to severe humidity, heat, cold or dirt.
Secure the model and the transmitter carefully when transporting them, as they may be seriously damaged
if they are free to slide about.
Never
operate the model on moving water (e.g. a river): as it could be washed away downstream if the
wind changes, if interference occurs, or if the battery is depleted.
If you have to
salvage
the model, take care
not to risk your own life or that of others.
Check regularly that the boat is completely watertight, as it may sink if too much water enters the hull.
Before every run check the model for damage which could allow water to penetrate the hull.
Allow the model to dry out thoroughly after every session.
Care and maintenance
Clean the model carefully after every run, and remove any water which has penetrated the hull. If water
gets inside any of the RC components, dry them out and send them to your nearest GRAUPNER Service
Centre for checking.
Clean the model and the transmitter using suitable cleaning agents only. A lint-free cloth is ideal.
Never
use
chemical cleaners, solvents, methylated spirit, white spirit or similar.
Notes on operating the model boat
When running the model, it is best to consider it as a powered sailing boat, i.e. the motor is more than just
an auxiliary power unit. The model’s scale appearance inevitably involves compromises which affect its
sailing qualities, and for this reason its handling under sail is not as good as that of less complex models.
This simply means that you will need to use the motor for additional forward thrust even when running the
boat as a sailing vessel.
