running the model, and then disconnect them immediately afterwards. On no account store the boat with
the batteries connected using the parallel lead.
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. The
external shaft bearing adjacent to the propeller must also be lubricated. 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, e.g. Order No. 570.
Assembling the model
•
Carefully unpack the model and the boatstand.
•
The superstructure must first be removed to open
the deck, so that the receiving system can be
installed; this is accomplished by carefully raising
the superstructure. IMPORTANT: first locate the
hook on the aerial tensioner and disconnect it from
the rear tip of the aerial on the rangefinder, then
cautiously raise the forward superstructure by the
turret bridge and the funnel. The rear part of the
superstructure can now be lifted off upwards.

Solder G2 plug to the wires attached to the motors,
referring to the wiring diagram on page 14 (+ is
positive, - is negative). Note that the motors are
wired in parallel, and are contra-rotating (turn in
opposite directions). Check the direction of rotation
of the motors when the battery is connected: the
propellers should rotate in such a way that the
model would be propelled forward. 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
recommend that you follow the tips outlined below,
which will make it easier to solder the connectors.
The procedure described will also help to avoid
damaging detail fittings on the model with the hot
soldering iron. TIP 1: remove the motors: first
unscrew the servo
grubscrews in the propellers so that the propellers
can be withdrawn. Now undo the motor retaining
screws (don't remove them completely) and slide
the motors forward until the shaft couplings are
exposed. Undo the grubscrews in the couplings
which clamp the motor shafts, then remove the
motors from the model. The motors and propellers
can be re-installed simply by reversing the whole
procedure. When you do this, check immediately
that the grubscrews are properly tight. TIP 2: if you have a friend to help you, ask him or her to support
the boat at an angle so that you can hold the motor wires outside the hull for soldering; any excess
solder will then fall away from the model. TIP 3: a "third hand" is a useful clamping tool which you can
use to hold the wires for soldering directly inside the model.
•
Check that the grubscrews in the shaft couplings and propellers are really tight, as they may have
worked loose in transit. You can check this by pulling on the propellers; if you find you can move the
shafts to the rear, then one of the grubscrews is loose. Tighten the offending item carefully, using TIP 1
