injuring people and animals standing on them.
Never run your boat in a protected site, an animal or plant sanctuary or a site of special scientific
•
interest (SSSI). Check with your local authority that the stretch of water you wish to use is suitable
for model boats.
Do not run the model in salt water.
•
Never run your boat in adverse conditions, e.g. rain, storm, strong wind, choppy water or strong
•
currents.
Read and observe the recommendations and instructions supplied with your radio control system
•
and accessories.
It is essential to use a radio control system set to SPCM mode, so that you can program a Fail-
•
Safe for the speed controller. This is a safety function which ensures that the model immediately
comes to a halt if interference should occur.
Before you run the model, check that the radio control system is working reliably, and that all
•
connections are secure.
If you insist on using dry cells as a power supply, please note that they must never be recharged.
•
Do not recharge any battery unless it is expressly stated to be 'rechargeable'.
The range of the radio control system must be checked before you even think about running this
•
boat. This involves carrying the model about 100 m from the transmitter, with both systems
switched on, while an assistant operates the transmitter for you. All functions must work perfectly
at all times, without the slightest hint of interference.
Ensure that the channel you intend to use is not already occupied by other modellers. Never run
•
the boat if you are not certain that your channel is free.
Remember that other radio equipment and transmitting apparatus may cause serious interference
•
to your model. If possible ensure that no such equipment is switched on in the vicinity, and is not
operated at any time while you are running the model.
Do not work on the power system without first disconnecting the motor from the drive battery.
•
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 exceed the recommended voltage of the drive battery. Increasing the voltage may cause
•
the motor and / or the speed controller to overheat, and the electrical leads can even melt. In the
worst case this may cause the model to go up in flames and be completely ruined.
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 and you do not remove the obstruction, the motor, speed controller or rudder servo
may be ruined due to overloading.
Dry cells and rechargeable batteries must never be short-circuited. Do not allow them to come into
•
direct contact with water.
Remove all batteries from the model and the transmitter prior to storing the boat.
•
Do not subject the model to high levels of humidity, heat, cold, vibration or dirt.
•
Secure the model, batteries and RC equipment carefully when transporting them. 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 battery fails or a malfunction occurs.
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 any model boat 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.
Open the boat and let it dry out thoroughly after each run.
•
During the initial test-runs it is essential to check that the propeller shaft system is watertight. If
•
water penetrates through the shaft tube, dismantle the system and lubricate it with plenty of
grease (Order No. 570).
