Care And Maintenance; Assembling The Model - GRAUPNER ARKONA Betriebsanleitung

No. 570.
•
NOTE: in the interests of safety the boat has a slight excess of power. This means that it is NOT
permissible to run the vessel at full power if the recommended batteries are fitted, as the drive motors
will overheat and could be damaged or even ruined. We recommend that you run the boat at scale
(i.e. reduced) speed, or run it for no longer than ten minutes at full-throttle. Allow the motors to cool
down between periods of high-speed running.

Care and maintenance

•
Clean the model carefully after every run, and remove any water which penetrates the hull. If water
gets into the RC components, dry them out carefully and send them to your nearest GRAUPNER
Service Centre for checking.
•
Clean the model and transmitter using suitable cleaning agents only. All you need is a lint-free cloth.
Never use chemical cleaners, solvents, methylated spirits, white spirit or similar.
•
Lubricate the propeller shafts at regular intervals by applying a small drop of oil to the bearings. Use a
type of oil which does not soil or contaminate water, e.g. Order No. 206. At the end of the season we
recommend that you remove the propeller shaft and re-lubricate it using water-neutral grease, Order
No. 570.

Assembling the model

•
Carefully unpack the model and the boatstand.
•
Carefully lift off the superstructure to open the
deck, so that the receiving system can be
installed. Take care not to break off any fittings.
Locate the hatch which provides access to the
rudder system for maintenance, and press it out
carefully from the inside.
•
Remove the motors by loosening the clamps
which hold them in place, and undo the shaft
couplings at the motor end. Solder G2 plugs to
the wires attached to the motors, then re-install
the motors in the hull. The motors are wired in
parallel, and spin in opposite directions (contra-
rotating propellers). Keep to the arrangement
shown in the wiring diagram (+ is red, - is black).
NOTE: the raised lug on the plastic housing of all
G2 connectors should always be the positive
terminal (red wire). If you keep consistently to this
principle, your batteries and speed controllers will
be interchangeable, and the system will be
protected against accidental reversed polarity.
•
Check that the propellers and the screws in the
shaft couplings are tight, as they may have co
loose in transit; re-tighten them if necessary.
•
Solder the connecting wires to the drive battery
terminals, and solder a G2 socket to the other
end. TIP: in the photo the solder joints are shown
insulated with pieces of heat-shrink tubi
insulating tape is also perfectly adequate.
•
Press the rubber grommets into the mounting
lugs of the rudder servo, and push the brass
sleeves through them from the underside. Fix the
servo in the model using the retaining screws
supplied. Set the servo to centre from the
transmitter, and fit the output arm on the servo
output shaft. Open up the centre hole in one arm
of the servo output lever using a 2 mm Ø drill, and
install a swivel pushrod connector. Set the servo
to centre and fit the output arm on
output shaft.
