Notes on building the model
•
When assembling the model please refer to the sketches in the supplementary English instructions.
•
These instructions should be considered as complementary to the illustrated instructions. It contains the
essential translations together with additional notes and tips for assembling and operating the boat.
•
If you do not understand the technical terms relating to sailing boats, you can download a sketch showing
the basic terminology from the Internet site www.micromagic-rc-segeln.de.
•
Before you start building the boat, please take the time to study the plan and read right through the
instructions. In general terms the instructions reflect the sequence of assembly.
•
TIP: the rigging cord is easier to thread through small holes and openings if you first apply a drop of cyano
to the end to harden it, then cut off the frayed extremity.
•
Please bear in mind that many tools can be dangerous if misused or handled carelessly.
•
Deploy the receiver aerial as high up in the hull as possible, and wind the wire outside the hull around one
of the shrouds. Reception will be very poor if the aerial is positioned below the waterline, and effective
range will be greatly reduced.
•
It is important to clean the joint surfaces carefully before gluing parts together. This is best accomplished
by sanding lightly, followed by wiping with a non-greasy liquid detergent or methylated spirit ("meths"). The
same applies to all surfaces which are to be painted, as this improves the paint's adhesion considerably.
•
Each bag containing small items and screws bears a printed number which is also shown in the assembly
drawings.
•
You will find the part numbers of the injection-moulded parts on a small plate adjacent to the individual part
on the sprue; the numbers will help you identify and allocate the plastic parts. Some of the injection-
moulded parts are readily identifiable, and these have no number plate, as they can be allocated easily by
referring to the stage sketches.
•
We recommend that you use high-viscosity cyano-acrylate ('thick cyano', e.g. Order No. 5821) for all joints
on this model.
Assembly instructions
•
Assemble the boatstand as shown. TIP: the holes in the bands can easily be pierced using a heated length
of metal wire; a match is quite sufficient to heat it. Be sure to produce one frame with long cross-pieces and
one with short cross-pieces.
•
Loosen the sheets (the pre-fitted black cords in the hull) and stick them to the outside of the hull using
adhesive tape, to ensure that they cannot slip back inside the hull during the following stages.
•
Screw the ring holders (D07) and the cleat (D08) to the hull. NOTE: take care not to over-tighten the
screws. Screw in place the holders (D03) for the lateral keels. NOTE: ensure that the small triangles of the
ratchet face outwards (see enlarged area of the sketch). Finally screw the latches (D01) to the hull; ensure
that they are able to rotate smoothly.
•
Stick the large RC box to the inside of the hull using double-sided adhesive tape. The correct position is
approximately central under the sheet guide.
•
Screw the spacers to the winch holder plate, then fix this assembly in the hull using the screws provided.
•
Fit the rubber gaskets on the rudder bushes, pass the bushes through the hull from the underside, then fit
the sleeves. Attach the spacer to the rudder servo holder, place this assembly on the rudder bushes, and
screw the winch holder in place. TIP: it is advisable to seal the rudder bushes on the inside with glue; we
particularly recommend an adhesive such as UHU alleskleber, as this glues the bushes in place as well as
sealing them against water penetration.
•
Press the rubber grommets into the winch mounting lugs, and push the metal spacer sleeves into the
grommets before screwing the winch to the winch holder. Please refer to the sketch for the following steps,
as it shows the exact position of the parts. Fit batteries in the transmitter and receiver battery box, and
switch both units on; set the winch to centre from the transmitter.
•
Screw the winch drum to the winch, first running the two sheets through the guide ring and then winding
both of them 1.5 times round the drum. Push the ends into the drum and tie them together. NOTE: ensure
that the sheets are allocated correctly between the drum and the ring; they must not cross over. Secure the
knot by tightening the retainer (E12). Screw the guide ring in place.
•
The winch assembly can now be screwed to the winch support plate. NOTE: ensure that the winch
connecting lead is still accessible. TIP: this can be achieved simply by taping it to the hull side.
•
Attach the guide sleeves to the servo output lever (D02). Cut off the three unwanted arms from the four-
armed servo output lever, then screw a guide sleeve to the remaining arm (see sketch for position). Screw
the rudder servo to the rudder servo mount, after fitting the small box under the servo. The box does not
need to be glued in place, as it is held in position by the servo itself. Route the servo lead through the hull
as shown in the sketch.
•
Lubricate the rudder shafts with grease, slide them through the rudder bushes and push the tillers onto the
