The Material:
The plastic used in this model set is 95% pure, impact-resistant ABS plastic. This material has a very
long life and will not become porous quickly like some other plastics. We have been using this material
for over 20 years in our production and, with the outside of the model lacquered, had the best results
with it. The best adhesive for this material is the Krick ABS special adhesive (order no. 80478). This
adhesive dissolves the ABS very slightly and virtually welds the components together.
However, due to its many small details, the deck could not be manufactured from ABS. We have used
polystyrene plastics instead.
Important: When gluing, please note that polystyrene (i.e. the deck) cannot be glued using the
ABS adhesive. The adhesive will not solve this material. In order to connect ABS with polystyrene,
"UHU allplast" or an epoxy adhesive should be used. Please make absolutely sure that you use this.
Cutting out the ABS Components:
In order to find the correct cutting edge, please look very closely at the drawings in these instructions.
Black-and-white triangular arrows show exactly from which side any edge should be cut with the knife.
The remainder is always shown as hatched on the drawing. Carefully score the edge several times,
then carefully break off the components. If large residues remain around the component, first cut off
the steep walls of the residues before getting to the actual component. Take particular care on
corners. It is better to score several times until the material is almost cut through otherwise cracks
could develop into the components which are uncontrollable because plastic does not have a structure
or directional fibres. Keep the remaining scrap bits, in particular the long straight strips of the hull
components. This is not waste material, some components are actually made from the strips of this
residue.
The Dive and Drive Kit (Order no. 20311):
This kit contains all the parts you need to build a functional diving model, except the radio remote
control, drive control and batteries. Some parts are also found in the basic kit which are put there
simply because it is easier to pack them there. You can quite easily tell which parts are in which kit by
the markings in the item list at the end of these instructions.
Besides the drive and dive kit, you also need the following items for the operation with remote control:
- Remote radio control, minimum 4 channels
- Drive control 12 V, 30 Amp, forward-reverse
- Drive control or forward-reverse switch to operate the pump
- Battery pack of 10 NiCd cells (recommended: min. 1300 mAh). Two battery packs of 2 times 5 cells,
or 4 and 6 cells have proven to be better for easier installation and removal.
Step 1
Cut out the hull halves (1 & 2) from the outside, as shown. First you cut off the large side walls of the
remaining material in order to obtain pieces that are easier to handle. Then score from the outside of
the hull in the edge of the hull component as per the drawing and carefully bend off the remaining
material.
