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 bearings adjacent to the propellers 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 outer motors should be wired in parallel for
contra-rotating action, and then soldered to G2
connectors. Solder G2 connectors to the
central motor at the same time, referring to the
wiring diagram on page 8 (+ is red, - is black).
Check the direction of rotation of the motors
when the battery is connected: the propellers
must 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 reversed polarity.
We 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: undo
the grubscrews in the shaft couplings which
hold the motor shafts, and withdraw the motors
from the model. The motors can be re-installed
simply by reversing the whole procedure.
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 screws in the shaft couplings, the motor retaining bars and the 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
as described above in order to
gain access to them.
IMPORTANT:
if you do
find the grubscrews are loose, apply a drop of
thread-lock fluid before tightening them, e.g.
UHU schraubensicher, Order No. 952, as
vibration could cause them to work loose again
while the boat is running.
•
Place the rudder servo in the opening in the
hull, and mark the position of the holes for the
servo retaining screws. Drill the holes using a
1.5 mm Ø bit, then screw the servo in place.
NOTE:
the opening is deliberately larger than
required for the recommended rudder servo;
