The vacuum-moulded parts are best cut out using a pair of scissors (we particularly recommend
our Lexan shears, Order No. 26), although in many areas a sharp knife (e.g. Order No. 982) can
be used. These parts feature moulded-in cut lines; always cut slightly outside the line so that you
can sand back carefully to the exact size.
•
Don’t throw away the scrap ABS material, as some is required for making small parts.
•
Sand all wooden parts carefully and apply several coats of GLATTFIX sanding sealer (Order No.
207) before installing them permanently. The printed wooden parts, such as the planked deck,
must not be brush-painted as the printed lines may smear. These surfaces should be sprayed with
a clear lacquer.
•
The electric motor or motors must be adequately suppressed: use at least one 470 nF capacitor
(Order No. 3588) for each motor, soldering the capacitor between the motor terminals as a bridge.
•
Deploy all electrical cables neatly, without crossing them over. It is essential that no positive (+)
wire or terminal should ever come into contact with a negative (-) one.
•
Use cable of adequate cross-section, capable of carrying the high currents which will flow when
the boat is running.
•
Install the receiver aerial well away from any high-current leads (min. distance 3 cm).
•
Before making any glued joints, be sure to clean the surfaces and remove all traces of grease. We
recommend sanding lightly, or wiping with a non-greasy cleaning agent. The same applies to
surfaces to be painted, otherwise the paint is unlikely to adhere well. Before gluing parts inside the
hull it is essential to roughen the surfaces with fine abrasive paper, and de-grease them with
acetone or similar solvent, otherwise you will not obtain strong, durable joints.

Be sure to read the instructions supplied with each adhesive! The building instructions include
notes on the right glue to use for particular joints; please keep to our recommendations. If you
use acetone, white spirit and other solvents as cleaning agents, special safety measures are
essential. Read the instructions on the label!
The hull
1.
The first step is to assemble the boatstand from parts (1), (2) and (3). Glue the joints with cyano
(cyano-acrylate) or UHU coll.
1.1
You may wish to apply strips of foam material to the stand to prevent scratches to the hull.
2.
Cut out the two shells of the vertical fin (5) from the scrap material as shown in the drawing, and
glue them together using Stabilit express.
2.1
Trim the fin to fit against the hull and glue it in place.
3.
The openings for the Voith-Schneider drive units are not pre-cut as standard. This is intentional,
to give you the option of fitting Schottel drive systems instead of the VS units, if you prefer.
3.1
If you are installing VS power units cut out two 84 mm Ø holes, ideally using a pair of dividers.
The centre of the circles is marked on the moulding.
3.2
When gluing the support rings in place
ensure that a line joining the two opposed mounting
holes is parallel to the centre bulkhead (13).
3.3
It is important to refer to the instructions supplied with the VS units when installing them.
4.
The guard plate (6) is a vacuum-moulding, and should be removed from its scrap material
leaving a height of 6 mm. Glue the plate to the baseplate (7), taking care to produce a
watertight joint.
4.1
Lightly score the baseplate (7) along the centreline, and bend it so that it follows the angle of
the guard plate.
4.2
Make the lateral braces (8) from brass tube as shown in the drawing, and glue them in the
guard plate.
4.3
The next step is to install the guard plate; at this stage please note that there must be about 1 -
2 mm clearance to the blades. We recommend gluing the braces in place using Stabilit express,
as this produces the strongest joints.
