The model requires some 40 kg to be loaded down to the water line. Weight of the model is approx 16 kg, complete with two lead batteries (one 12 V, one 6 V). The ballast tank will take some 22 litres (kg) so extra lead is required to reach the 40 kg. But it does not have to be at the water line every time....
Functions. Motor, rudder, bowthruster: proportionally controlled. Lights: sailing lights, deck house and bridge lights, deck lights, lights in the signals mast, crane arm lights etc, pumps for loading/discharging ballast water: On/off switches. Crane arms and turning and cargo hatches will be operated via a separate radio system. At present I am using a 12 channel Graupner radio which is used to its full capacity
Most electronic items are Actions Electronics (the Component shop) which greatly has helped making a tidy and "clean" wiring.
During the build a fair amount of single malt has been consumed in order to inspire and support the builder.....
