Important Safety Advice

You have purchased a model aircrraft kit which can be used to build a fully functional
radio control model, together with the nessesary aditional parts and accessories. The
tit manufacturer GRAUPNER have no control over customer compliance with
assembly and operating instructions as well as the installation, operation, use and
maintenance of the components associated with the model. Therefore GRAUPNER
accept no liability for losses, damages or costs which arise from operational or
behavioural errors or which are in any other way connected with the aforementioned
kit. If not stipulated by law the company GRAUPNER is under no obligation to pay
compensation for whatever reason, including personal injuries, death, damage to
buildings as well as damages caused by loss of turnover or business, by interruption
of business or other indirect or direct consequential damages resulting from the
operation of the model aircraft. Under all circumstances and in any case the total
liability is limited to the amount that has actually been paid for this model.

The assembly and operation of the model is undertaken solely at the operator’s risk.
Cautious and considerate handling on the part of the user when operating the aircraft
is essential in order to prevent personal injuries and damage to property.

During the construction phase
Please observe the safety and handeling instructions of the manufacturers when
handling adhesives and solvents. Some adhesives and solvents can cause health
problems and material damage if not used correctly. Dispose of leftover glue and
paint safely by returning them to a specialist dealer or taking them your local waste
disposal collection site. Be aware that handling sharp balsa knives and pins can
easily lead to injuries. Ensure that children have no access to tools, glues or
varnishes.A generously sized clear working space is a particular advantage for all
handicrafts.

Please seek the advice of an experienced aero-modeller for assistance with
any aspect of the construction processes with which you are unfamiliar.

Flight Operations

Never fly your ALPINA 3001 CHAMP PRO in nature reserves or landscape
conservation areas. Always give due consideration to the habitats of animals and
plants as trees. Bushes and shrubs serve birds for nesting and bringing up their
young.

duties arising from it, excluding the provisions of international private law and UN
Sales Law.

The following points must always be observed:

• Check before launching the model that the remote control system is functioning
correctly and that all mechanical and ellectrical connections are secure.

• The batteries are fully charged and the range of the remote control system is
checked. In particular the transmitter and and receiver batteries must be charged.

• Check that the radio control channel in use is free. Never fly your model if you are
unsure whether the channel is free.

• Follow the recommendations and instructions supplied with your remote control
system and accessories.

• Ensure that all control servos are operating freely and not mechanically restricted.

• Batteries must not be short-circuited.

• Remove the batteries for transport and whenever the model is not in use.

• Do not expose your model to extreme temperatures, high levels of humidity or

dirt.

• Secure the model and RC-components during transport against damage or
slipping.

• IMPORTANT: The model’s built-in battery must not be disposed of with
household waste. The battery must be disposed of in battery recycling containers.

• IMPORTANT: The model and the transmitter must not be disposed of with
household waste, but must be taken to a recycling depot for disposal as electronic
scrap. Contact your local council for further information.

Pre-Flight Checks

Before each flight check the correct function and range of the radio control system by
switching on the transmitter as well as the receiver, extend the transmitter antenn
and check from an appropriate distance that all control surfaces are operating
correctly, both in terms of magnitude and sense.
Depending on your level of experience and particularly in the case of the first flighgts,
it is advantageous to have an experienced helper by your side to offer assistance
with the pre-flight checks and first flights.

Care and Maintenance

• Clean the model after each flight. Only use suitable cleaning products for cleaning
the model and the RC-components. Contact your specialist dealer for information
about this.

• When cleaning decor print products (decor sheets, design foils) detergents which
contain solvents must not be used as they can damage or destroy prints. Please
use warm soapy water and a soft cloth for cleaning.

Notes about the construction of the model

Before commencing the construction of the model you should take time to read
through these instructions in their entirety. Be particularly aware of potential dangers
when using sharp tools.

Remove any grease residue from each adhesive joint before bonding. This can for
example be achieved by sanding and treating with a non-relubricating detergent.
Before glueing together parts ensure that the relevant surfaces (especially with
regards to the fibreglass fuselage) are carefully roughened with a suitable grade
sandpaper and thoroughly degreased, e.g. with acetone. Otherwise sufficient
adhesion cannot be guaranteed.

Necessary tools for the construction of ALPINA 3001 CHAMP PRO

Pencil (lead grade HB), a set square as well as a tape measure or meter rule,
household scissors, a narrow sharp knife such as e.g. a balsa knife, order no. 980,
an electric miniture and assorted drill bits.

Glueing of materials

The following table lists some examples of adhesive connections. This list by no
means claims to be complete.

Material Usage (example) Adhesive Type
Order no.
_________________________________________________________________
Glass-fibre Canopy cover with fixing wire UHU plus endfest 300
reinforced polymers order no. 950.43

wire

Glass-fibre Fuselage with servo board UHU plus endfest 300
reinforced polymers order no. 950.43
with wood

Note:

Roughen the surfaces to be glued in the fuselage with fine-grained sandpaper to
remove any adhesive release agents. Wipe off any grinding dust. The glossy surface
of the fuselage must be rendered matt as otherwise good bonding of the adhesive
with the fuselage cannot be guaranteed. For information about bonding the
individual parts to one another follow the processing instructions of the adhesives.
When using adhesives containing solvents ensure that your work area is well
ventilated. Follow the instructions provided by the manufacturers.

Important Note

No adhesives which contain solvents, in particular no superglue, must be used
for any glueing which comes into contact with the polystyrene in the wings
cores. These adhesives lead to the large-scale destruction of the styrofoam; the
part consequently becomes unusable. Always use solvent-free adhesives for
this process. We recommend glueing with UHU-Endfest or epoxy resin
thickened with cotton flocks. However, do avoid using 5 min Epoxy for
bondings which are relevant for statics or control technology!

Tip: Using with Epoxy Resins

Epoxy alone is not a viable adhesive! However, the addition of appropriate
additives turns laminating resin into a variety of excellent adhesives. Choose
the appropriate additive to create an adhesive which perfectly matches the job
requirements:

1. Chopped cotton fibre flocks produce a tough, but flexible bond.

2. Superfine glass fibres produce a very hard, but well grindable bond.

3. Micro-balloons produce a highly effective, lightweight filler.

capacity.

Re-chargeable batteries are recommended for the receiver and transmitter as they
provide the highest level of safety. For suitable battery chargers see our catalogue.

Assembling the ALPINA 3001 CHAMP PRO

Only begin the assembly after you have familiarised yourself with the individual
components and construction stages. In the event that a component should give
reason for complaint this should be communicated to your specialist dealer prior to
the start of construction.

The wings

Feel with your fingertips for the servo openings for the aileron and flaps servos, then
melt them free with a hot soldering iron or cut free with a sharp balsa knife and adjust
to accomodate the control horns as nesssary. As shown in both photos glue in the
GRP control horns using suitably thickened epoxy resin.

8

The depth of the servo openings is mechanically prefabricated; it may, however, be
necessary to adjust the depth of the openings by removing further Styrofoam (as
much as possible, until veneer with a fibre orientation transverse to the wingspan
becomes visible).

While waiting for the the adhesive to cure, prepare the servo control horns as shown
in the photo. The outer hole may need to be drilled open to a diameter of 1,6 mm to
accomodate the push-rod.

With servo in the centre (neutral) position the prepared servo levers are mounted on
each respective servo and tightly screwed down. In order to do this, place the servo
via the remote control in neutral position.

9

Before glueing the servos on the covers the connection cables must be soldered onto
the extension cables which have already been pre-fitted into the wings and the
mounting links must be removed from the servos. When doing so ensure that the
correct polarity is applied, i.e. the correct colour-coded cables are soldered together.
As shown in the photo isolate the soldering joints with heat shrinkable tubing which
must be pushed onto the cables before soldering.

Now the servos are glued onto the servo covers; as shown in the photo. The servo
lever must be in the centre of the output fairing and the servo must be about 8 mm
from the edge. The servo cover and the servo casing itself must be well roughened
with sandpaper. Superglue (order no. 5821) can be used as adhesive here. Ensure
that the servo is placed in the correct position at the first attempt at assembly.
Note: When using superglue it is not possible to move the item at a later stage in
order to correct its position.

The push-rods for the ailerons and wing flaps are made from the M2 threaded rods
supplied in the hardware pack and are fitted with a M2 lock nut and a M2 clevis. The
aileron push-rods must be bent so as to measure 40 mm from the mount point on the
servo lever to the clevis pin. For the wing flaps the distance must be about 45 mm.
The exact length can be adjusted after screwing the covers is adjusted by turning the
clevis in or out.
