Assembling the model
• Carefully unpack the model, the separately packed radio aerial 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; it is only secured with double-sided
adhesive tape.
• Solder G2 plugs to the wires attached to the
motors, which are wired in parallel, and rotate in
opposite directions (contra-rotating propellers).
Ensure that the motors spin in the correct
directions: when the battery is connected, the
propellers should rotate in such a direction 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.
• Check that the propellers and the screws in the
shaft couplings (arrow) are tight, as they may
have come loose in transit; re-tighten them
carefully if necessary. IMPORTANT: if the
grubscrews are loose, apply a drop of thread-
lock fluid to them, e.g. UHU schraubensicher,
Order No. 952, as vibration could cause them to
work loose again while the boat is running.
• Drill out the centre hole in the double-ended
servo output lever to 2 mm Ø, and connect the
end of the rudder pushrod to it. Fit the retaining
clip to keep the pushrod in place. Don’t fit the
output lever on the servo at this stage.
