Caution: this model is not a toy!
If you are a beginner to this type of powered model, please ask an experienced
model flyer for help and support. If you attempt to operate the aeroplane without
knowing what you are doing, you could easily injure yourself or somebody else.
Please keep your safety and well-being in mind at all times.
Important: before you start construction
Even if you have already built a large number of RC models please read right through
these instructions and check that all the kit components are actually present. We
have taken great trouble to keep construction as simple as possible, without making
any compromises in the area of safety.
Note regarding the film covering
Minor creases or bubbles may develop in the film covering due to major fluctuations
in weather conditions (temperature, humidity etc.); in rare cases you may even find a
slight warp in a component. These minor faults are in the nature of film-covered builtup wooden structures, and can easily be corrected using a heat gun, as commonly
used for modelling.
Creases: Blow warm air over the area and rub down with a soft cloth.
Wing warp: Hold the panel twisted gently in the opposite direction to the warp,
and apply warm air to remove the creases from the covering.
Caution! do not heat the film more than is absolutely necessary. If the air or the iron
is too hot, the film may melt and holes may be formed.
This aeroplane is highly pre-fabricated and can be built in a very short time. However,
the work which you have to carry out is important and must be done carefully. The
model will only be strong and fly well if you complete your tasks competently - so
please work slowly and accurately.
When self-tapping screws have to be screwed into wood, apply a little white
glue to prevent them shaking loose: just squirt white glue into the hole before
fitting the screw.

Notes on building the model
• Before you start building the aircraft it is essential to study the plan and read right
through the instructions. Please bear in mind the dangers inherent in the handling
of tools.
• When preparing wiring, be sure to use cable capable of carrying the currents like-
ly to flow when the model is flying.
• Deploy the receiver aerial as far away as possible from high-current cables (at
least 3 cm).
• Remove all traces of grease from the joint surfaces of components which are to
be glued. A good method is to sand lightly before wiping with a non-greasy liquid
detergent solution. The same applies to surfaces which are to be painted, otherwise the paint will not adhere permanently. Before gluing any GRP parts, and
GRP fuselages in particular, the joint surfaces must be sanded thoroughly with
fine-grit abrasive paper before de-greasing with a solvent such as acetone. This
is the only method of obtaining durable glued joints involving GRP parts.

Assembling the PIPER CHEROKEE
Wing and undercarriage
Please don’t start assembling the model until you have checked the kit components
and the building instructions, and are familiar with the construction procedure. If you
are not happy with any component, kindly return it to your model shop without delay.

Mark a centreline on all the aileron hinges using a pencil, as shown in the photo.
The hinges can now be inserted in the ailerons as far as the pencil lines, and glued in
place. We recommend thick cyano for this: push the hinges into the slots to a depth
of about 1 mm, apply cyano on both sides, then push them in as far as the marked
lines.
Use your fingertips to locate the holes in the ailerons for the horns, and melt the film
over them using the tip of a hot soldering iron.
When the glue has set hard, insert the projecting hinges into the slots in the wings to
check alignment; you may need to adjust the slots in the wings slightly.
Now repeat the above procedure: push the hinges into the wing to a depth of about 1
mm, apply cyano on both sides, then push the ailerons into place, leaving a gap
about 0.5 mm wide at the hinge line.

Modifications reserved. No liability for printing errors. 06/2010
6
Lengthen the aileron servo leads with the appropriate extension leads, and fit a piece
of heat-shrink sleeve round each connection to prevent it working loose; a drop of
cyano also works well. Set the servos to centre from the transmitter, and fit the output
arms on the output shafts.
Set the servos to centre by connecting them to the receiving system. The wingmounted servos can now be attached to the support blocks using the retaining
screws supplied with them: the first step is to push the rubber grommets into the
servo mounting lugs, followed by the brass tubular spacers, with the flange on the
underside. The spacers are easier to fit if you slip them on a suitable screwdriver first.
Drill 1.5 mm Ø pilot-holes in the support blocks, using the metal spacers as a guide,
then fit the servo retaining screws as shown.
The servo leads can now be pulled through the wing panels using a length of thread:
tie the thread to the servo lead just behind the connector, then pull it through until it
appears at the root rib.
Run the servo leads out of both wing panels through the holes adjacent to the root
ribs, then temporarily fit cable ties on them to prevent them slipping back inside.

Modifications reserved. No liability for printing errors. 06/2010
7
Fit short pieces of heat-shrink sleeve over the landing flap hinges to prevent the jaws
opening.
On the underside of the wing you will find marked points indicating the position of the
flap hinges; note that the pivot axis of all the hinges must be exactly the same distance from the wing trailing edge. Temporarily fix the hinges to the wing with one
screw, as shown in the left-hand photo, then set the hinge assembly exactly at rightangles to the wing trailing edge using an engineer’s square or setsquare before fitting
the remaining two screws to secure the hinge to the wing. Now offer up the landing
flaps to the wings and tape them in place temporarily. Fit the retaining screws to fix
the hinges to the flaps.
On one aileron remove a disc of covering film the same size as the base of the aileron horn socket. Assemble the threaded socket, the cheesehead screw, the horn
lug and the nut as shown in the photo. Repeat for the second aileron.

Modifications reserved. No liability for printing errors. 06/2010
8
Insert the horns in the holes in the ailerons and set them to the correct height (see
photo). The horns can now be glued in the holes in the ailerons. These joints must be
strong, and we recommend the use of thickened 24-hour epoxy for durability.
The aileron and landing flap pushrods are assembled as shown in the following sequence of photos.
Set the servo and each control surface to neutral, then adjust the length of the pushrod and apply a drop of UHU thread-lock fluid to prevent it moving out of adjustment.
The next step is to locate the undercarriage channels in the wings using your fingertips. Remove the film over the channels using the tip of a hot soldering iron.
GRAUPNER GmbH & Co. KG D-73230 KIRCHHEIM/TECK GERMANY
Modifications reserved. No liability for printing errors. 06/2010
9
Now insert the undercarriage leg in the channel prior to marking the position of the
two saddle clamps. Place the clamps and the undercarriage fairing on the wing as
shown in the photo.
Drill pilot-holes in the wings to suit the retaining screws, then screw the clamps and
the wheel fairing support block to the wing.
You will need to file away the inside of the two wheel fairings to provide clearance for
the wire undercarriage units. Note that the convex side of the wheel fairings must
face outwards. The wheels can now be attached to the axles using collets and grubscrews. Apply UHU thread-lock fluid to the grubscrews to prevent them working
loose.
The wheels and wheel fairings must be aligned exactly parallel with the fuselage centreline.
Use your fingertips to locate the holes for the wing retainer screws in the wing root
area, and remove the covering film over them using the tip of a hot soldering iron.
The final stage on the wings is to glue the GRP wingtips to the tip ribs using UHU
Holzleim express, Order No. 958.60. Tape the tips in place as shown in the photo, to
prevent them shifting while the glue is hardening.

Fuselage, tailplane, fin and noseleg
The covering film has to be removed from the mating surfaces of the fuselage and fin
before the fin can be glued in place, as shown in the photos.
Use a felt-tip pen to mark the outline of the fuselage on the tailplane, then run a hot
soldering iron just inside the marked line before peeling off the unwanted film.
Apply UHU Holzleim express, Order No. 958.60, to the tailplane saddle, place the
tailplane in position, and press it firmly into place. Check that the tailplane is ‘square’
to the fuselage in all three axes, then pin or weight it down to prevent it shifting while
the glue hardens.

Modifications reserved. No liability for printing errors. 06/2010
11
Allow the glue to set hard, then push the fin into the slot in the fuselage turtle deck.
Mark the outline of the fuselage on the fin using a felt-tip pen, and the outline of the
rear part of the fin on the top of the fuselage.
Use the tip of a hot soldering iron to melt through the film just inside the marked lines,
and peel off the unwanted material. Apply glue to the fin, the fin slot and the in-fill
piece. Push the fin into its slot, and fit the in-fill piece on the tailplane. The elevator
and rudder can now be attached to the tailplane and fin by fitting the hinges in the
manner already described for the ailerons.
Allow the glue to set hard, then glue the horns in the rudder and elevator as previously described.
Check that the flange of the threaded sockets lies flat on the control surfaces, and
makes good contact all round.
Allow the glue to set hard, then connect the clevises to the horn lugs as shown in the
photos. Squeeze the crimp sleeves firmly onto the steel pull-cables for the rudder
linkage.
Install the rudder and elevator servos in the servo plate as shown in the photo, using
the screws supplied in the servo accessory packs. Drill pilot-holes for the screws before fitting them.

Modifications reserved. No liability for printing errors. 06/2010
12
Screw an M2 locknut onto the threaded end of the elevator pushrod, followed by a
clevis. Screw the clevis in or out until the elevator is exactly at centre when the servo
is at neutral. Adjust the pull-cable (closed loop) rudder system so that the rudder and
servo are exactly at centre, and both cables are under equal and moderate tension,
i.e. there is no lost motion (slop) in the control system.
The two pilots’ seats, the joysticks, the dummy baggage and the sunshield have to be
installed in the cockpit before the canopy is attached to the fuselage, as shown in the
photos below.
Cut out the sunshield along the marked lines, and fix it over the control panel as
shown in the right-hand photo. This is most easily accomplished using strips of clear
adhesive tape.
The dummy baggage can simply be glued in the appropriate position using UHU
ALLESKLEBER Kraft.

Modifications reserved. No liability for printing errors. 06/2010
13
Prepare the baggage straps from the materials supplied, and attach them as shown.
The canopy can now be fixed to the fuselage. Place the canopy accurately over the
cockpit: it should end flush with the black film at the front, and with the red film on
both sides. Fix the canopy to the fuselage in this position using strips of clear adhesive tape.
Glue the dummy lighting units to the top of the fin and rudder using UHU ALLESKLEBER Kraft, as shown in the photo.

14
Install the nosewheel steering servo in the forward servo plate using the retaining
screws supplied in the accessory pack.
Fix the noseleg in the bracket by tightening the screw in the collet. Install the nosewheel steering cables as shown in the photographs.
As with the other control systems, it is important to check that the nosewheel is exactly at the ‘straight ahead’ position when the steering servo is at centre. Later the
nosewheel steering servo and the rudder servo can be connected to separate channels and superimposed using a mixer at the transmitter.
The nosewheel spat can now be attached to the yoke of the noseleg unit. Drill two
mounting holes in the spat as shown in the left-hand photo below. Take care to position the spat correctly, i.e. to drill the holes in the correct side of the moulding.
GRAUPNER GmbH & Co. KG D-73230 KIRCHHEIM/TECK GERMANY
Modifications reserved. No liability for printing errors. 06/2010
15
A hole also has to be drilled in the wheel spat to clear the screw-head of the wheel
axle, as shown in the right-hand photo.
The spat can now be screwed to the noseleg, fitting the wheel on the axle with two
collets at the same time.
Installing the engine
Attach the engine to the two-part engine mount as shown in the photo.
Note that the engine’s mounting lugs should end flush with the front edge of the engine mount arms.
If you wish to install a different power plant, note that the distance between the pro-
peller driver and the rear face of the engine mounts needs to be about 165 mm.
The next step is to mark the position of the engine mount holes on the firewall. Ensure that the centreline of the engine coincides with the marked lines on the firewall.

Modifications reserved. No liability for printing errors. 06/2010
16
Fix the engine mounts to the firewall using the screws supplied in the kit.
Assemble the parts for the throttle servo mount, and glue the completed mount in the
slots in the firewall. Install the servo when the glue has set hard.
Install the pull-cable carburettor linkage as shown in the photo.
The ignition unit for the G 26 should be screwed to the firewall on the left-hand side.

17
Assembling and installing the fueltank
Cut a piece of fuel tubing and push it onto the fueltank clunk pick-up. Push the free
end of the fuel tubing onto one of the tubes in the fueltank stopper, and check that
the pick-up will be able to move freely inside the tank without binding or jamming
when the stopper is in place. Use a heat-gun or match to heat the other two plastic
tubes gently, so that they can be curved: one should face down (later used to fill the
tank); the second faces up (serves later as overflow when the tank is filled). Extend
each tube with a piece of fuel tubing so that they extend to the top and bottom of the
tank respectively.
Now push the tank stopper, complete with pick-up and pre-formed tubes, into the
throat of the fueltank, and tighten the cross-point screw to clamp the stopper in place.
It is essential to tighten the screw to the point where the tank is completely sealed.
You can check this by holding the tank under water and blowing hard into the fuel
tubes: any air bubbles indicate a leak which must be eliminated.
Connect a further length of fuel tubing to each stub tube projecting from the fueltank
stopper.
Mark the individual fuel lines so that you can identify which is the fuel feed (to the
engine), which is the overflow, and which is the filler line.
Push the fueltank into the tank compartment behind the firewall, passing the three
fuel lines through the hole in the bulkhead.
The fuel tube connected to the clunk should be connected to the engine’s carburettor, while the overflow should run down and out of the model. The fuel filler line can
later be routed out of the model through a hole in the cowl. Secure the fueltank carefully, so that it cannot shift in flight.

18
The next step is to cut or file out openings in the cowl to clear the silencer exhaust
pipe, sparkplug, etc.; the position and extent of the openings vary according to the
engine you are using. Position the cowl on the fuselage in such a way that there is
about 2 mm clearance all round between the front face of the cowl and the rear face
of the spinner backplate. Fix the cowl to the fuselage using four pan-head selftapping screws, as shown in the photos.
Cut out the wing-fuselage fairings along the marked lines. Trim them to fit neatly before gluing them to the fuselage using UHU ALLESKLEBER Kraft.
The ON / OFF switch for the engine ignition system should be installed in the lefthand fuselage side, as shown in the photo.
GRAUPNER GmbH & Co. KG D-73230 KIRCHHEIM/TECK GERMANY
Modifications reserved. No liability for printing errors. 06/2010
19
The ON / OFF switch for the receiving system is installed in the right-hand fuselage
side.
Balancing the PIPER CHEROKEE
The completely equipped model, with the fueltank empty (or the flight packs fitted),
should balance level at a point about 95 - 100 mm aft of the wing root leading edge,
ideally with the nose inclined slightly down. It is easier to balance the Cherokee when
it is held inverted. If necessary, adjust the position of the receiver batteries until the
model balances at the stated point. Before flying the aircraft, set the transmitter trims
to centre and ensure that all the control surfaces are also exactly at centre (neutral).
Control surface travels for normal flying
Ailerons 30 mm up, 15 mm down
Elevator 25 mm up and down
Rudder 45 mm right and left
Landing flaps take-off 12 mm down
landing 60 mm down
We recommend that you set 30% Exponential values at the transmitter.
Important:
When fitting and adjusting the various linkages you should ensure that they move
freely, without binding, are able to move to their full extent - including trim travel - and
are not obstructed mechanically at any point.
When you move the rudder stick to the right, the rudder should also deflect to the
right (left stick: left rudder). Pull the elevator stick back towards you, and both elevators must deflect up (stick forward: elevator down). If you move the aileron stick to the
right, the right aileron should rise, the left aileron fall. When you move the throttle
stick forward, the engine should run at full power; pull the throttle stick back, and the
engine should idle. Move the trim right back to its end-point, and the engine should
reliably stop. The landing flaps are best assigned to a three-position switch.
All that remains is for all of us to wish you many hours of pleasure flying your PIPER
CHEROKEE.
Yours - the team !

Safety notes and warnings
relating to model aircraft powered by internal-combustion engines
• Be sure to read right through the instructions covering assembly and operation of your model before you attempt to operate it for the first time.
• These safety notes are an integral part of the instructions. Please keep
them and the operating instructions in a safe place. If you ever dispose of
the model be sure to pass them on to the new owner.
• Powered model aircraft are very demanding and potentially dangerous machines, and call for a high level of technical knowledge and skill from the
operator, together with a responsible attitude.
• Powered model aircraft are not suitable for young persons under eighteen
years of age.
• Young people should only be permitted to operate this model under the
instruction and supervision of an adult who is aware of the hazards involved in this activity.
• The operator of the model must be in full possession of his bodily and
mental faculties. As with car driving, operating a model aircraft under the
influence of alcohol or drugs is not permissible under any circumstances.
• Radio-controlled model aircraft may only be employed for the purpose intended by the manufacturer. They must never be used as man-carrying machines. Any other use of this model is prohibited.
• A radio-controlled model aircraft can only work properly and fulfil your expectations if it is built very carefully and in accordance with the building instructions. Do not make any modifications of any kind to the design features or materials. If you wish to avoid injuring people and damaging property it is essential to be careful and painstaking at all stages of building and
operating your model. Nobody would climb into a full-size light aircraft and
try to fly it without completing a course of training first. Model flying is a
skill which has to be learned in just the same way. We suggest that you ask
for help from an experienced model flyer, or join a model club or flight
training school. Your local model shop and the specialist magazines are
excellent sources of information.
• It is fundamentally essential to set the Centre of Gravity (C.G.) and control
surface travels correctly. Adjust the model until they are exactly correct.
• Radio control system: satisfy yourself that your frequency is vacant before
you switch on. Check your RC system regularly as its components eventually wear and need to be replaced or repaired. Radio interference caused by
unknown sources can occur at any time without warning. If this should
happen, your model will be uncontrollable and completely unpredictable.
Never leave your radio control system unguarded, as other people might
pick it up and try to use it. Your RC system can only work reliably if the batteries are kept fully charged.
• Don’t ignore our warnings. They refer to materials and situations which, if
ignored, can result in fatal injury or permanent damage.
• You alone are responsible for the safe operation of your radio-controlled
model aircraft and engine.

• If you have any questions regarding the safe operation of your RC model
aircraft, please turn to your local model shop in the first instance as the
staff will be pleased to help you.
• Propellers and other rotating parts which are powered by an engine represent a permanent hazard and present a real risk of injury. Don’t touch them
with any part of your body. For example, a propeller spinning at high speed
can easily slice off a finger.
• Keep well clear of the rotational plane of the propeller. You never know
when some part may come loose and fly off at high speed, hitting you or
anybody else in the vicinity. Never touch the revolving propeller with any
object.
• Take care with loose clothing such as scarves, loose shirts etc. Flapping
cloth can easily be sucked into the area of the propeller and then get tangled in the blades. This is extremely dangerous.
• If there are passers-by or spectators at your flying site, make sure that they
are aware of the dangers inherent in your activity, and insist that they keep
a safe distance away (at least 5 m).
• Radio-controlled models should only be flown in “normal” weather conditions, i.e. a temperature range of -5° to +35° C. More extreme temperatures
can lead to changes in battery capacity, material characteristics and other
unwanted effects.
• Model fuels are toxic; do not allow them to come into contact with your
eyes or mouth. Fuel should always be stored in clearly marked containers,
out of the reach of children.
• Never run an internal combustion engine in an enclosed space such as a
cellar, garage etc. Model engines produce lethal carbon monoxide gas just
like full-size engines.
• Engines should only be run in the open air!
• Adhesives and paints contain solvents which may be hazardous to health
under certain circumstances. Read and observe the notes and warnings
supplied by the manufacturer of these materials.
• Model fuels are volatile and highly inflammable. Keep them well away from
open flames, excessive heat, all possible sources of sparks and anything
else which could result in a fire. Do not smoke in the immediate vicinity of
fuel or fuel vapours.
• Model engines generate a lot of heat. The engine and silencer in particular
become very hot when running, and stay at a high temperature for quite a
while. Touching the hot parts can give you serious burns, so take care especially when carrying out adjustments - wear protective gloves. Hot engines can even start a fire under certain circumstances.
• When the engine is running it expels hot toxic gases from the exhaust together with very hot fluid combustion residues which can burn you if you
are not careful.
• Remove all unused fuel from the fueltank and engine after every session.
• Every time you intend to operate your model check carefully that it and
everything attached to it (e.g. propeller, linkages, control surfaces etc.) is in
good condition and undamaged. If you find a fault, do not fly the model until you have corrected it.

• Model engines are usually started with the help of an electric starter which
should be fitted with the appropriate adaptor where necessary. With fixedwing models an alternative is to use a “chicken stick” - a length of thick
wooden dowel with a piece of water hose pushed over it
• Many model engines are very noisy, producing a sound level much higher
than 85 dB (A-weighted), which implies that you should wear ear defenders.
Never run a engine without the silencer fitted. Even with a silencer, model
engines can easily disturb your neighbours. Don’t run engines when other
people expect peace and quiet.
• If you start your engine when the model is standing on loose or sandy
ground, the propeller will suck up sand and dust and hurl it around, and it
could easily get in your eyes and do damage. Wear protective goggles at
such times.
• Take care that the sparkplug clip and the lead cannot get tangled in the
propeller or other rotating parts. Check the throttle linkage too.
• Take particular care when carrying the model with the engine running. Hold
the rotating parts well away from you!
• Be sure to keep an adequate supply of fuel in the tank. Don’t continue to fly
the model until the tank is drained dry.
• Never fly directly over people.
• Never fly directly towards people.
• Keep a safe distance from residential areas: at least 1.5 km ‘as the crow
flies’. The best solution is to join a model flying club and use the approved
flying site. Always keep well clear of high-tension overhead cables.
• Whenever you are working on the engine, make sure that you are on a safe
surface and cannot slip. Get used to holding the model really securely.
• Take-off and landing strips should be kept free of unauthorised people and
movable obstacles, particularly when a model is using the strip.
• Watch the aeroplane constantly while it is in the air. Models must always
give way to full-size aircraft.
• Don’t operate your aircraft from public roads, squares, school playgrounds,
public parks or sports grounds etc., and ensure that you are always in full
control of the model.
• It is important that you are able to stop your engine at any time. This is
achieved by adjusting the throttle so that the barrel closes completely
when you move the throttle stick and trim to their end-points. If this does
not work, pinch the fuel feed line between your fingers or pull it off the carburettor. Never try to stop the engine by grasping the flywheel, propeller or
spinner!
• All model flyers should behave in a manner which minimises the danger to
people and property. Never act in any way which will disturb other flyers
and jeopardise safe, orderly flying at the site.
• In legal terms our models are classed as aircraft, and as such are subject to
legal regulations and restrictions which must be observed.

• Our brochure “Modellflugrecht, Paragrafen und mehr” (Model Aviation Law,
Legal Requirements and more) is available under Order No. 8034.02, and
contains a summary of all these rules. Your local model shop should have a
copy which you can read. Models fitted with glowplug engines may only be
flown with the landowner’s permission, and third party insurance is mandatory. There are also Post Office regulations concerning your radio control
system, and these must be observed at all times.
• Please don’t misunderstand the purpose of these notes. We only want to
make you aware of the many dangers and hazards which can arise if you
lack knowledge and experience, or work carelessly or irresponsibly. If you
take reasonable care, model flying is a highly creative, instructive, enjoyable and relaxing pastime.
• This model is highly pre-fabricated and can be built in a very short time.
However, the work which you have to carry out is important and must be
done carefully. The model will only be strong and fly well if you complete
your tasks competently - so please work slowly and accurately.
Important Safety Notes
You have acquired a kit which can be assembled into a fully working RC model when
fitted out with suitable accessories. However, we as manufacturers have no control
over the way you build and operate your RC model aircraft, nor how you install, operate and maintain the associated components, and for this reason we are obliged to
deny all liability for loss, damage or costs which are incurred due to the incorrect use
of our products or due to incompetent behaviour on the part of the user, or which are
connected with such operation in any way. Unless otherwise prescribed by binding
law, the obligation of the GRAUPNER company to pay compensation, regardless of
the legal argument employed, is excluded. This includes personal injury, death, damage to buildings, damages due to loss of business or turnover, interruption of business or other direct or indirect consequent damage whose root cause was the operation of the model.
The total liability in all cases and under all circumstances is limited to the amount of
money which you actually paid for the model.
This model is built and flown at the sole and express responsibility of the operator. The only way to avoid injury to persons and damage to property is to
handle and operate the model with the greatest care and consideration at all
times.
According to the new regulation of §103 Paragraph 3 of the LuftVZO (German Aviation Approvals Office), all model aircraft - whether slow-flyer, park-flyer, glider, or
model aircraft propelled by any form of power plant - must be insured before the
model is operated. If you are not sure about this, please ask at your local model shop
where the staff will be glad to advise you.
These safety notes must be kept in a safe place. If you ever dispose of the model, be
sure to pass them on to the new owner.

Manufacturer’s declaration:
If material defects or manufacturing faults should arise in a product distributed by us
in the Federal Republic of Germany and purchased by a consumer (§ 13 BGB), we,
Graupner GmbH & Co. KG, Henriettenstraße 94-96, D-73230 Kirchheim/Teck, Germany, acknowledge the obligation to correct those defects within the limitations described below.
The consumer is not entitled to exploit this manufacturer’s declaration if the failure in
the usability of the product is due to natural wear, use under competition conditions,
incompetent or improper use (including incorrect installation) or external influences.
This manufacturer’s declaration does not affect the consumer’s legal or contractual
rights regarding defects arising from the purchase contract between the consumer
and the vendor (dealer).
Extent of the guarantee
If a claim is made under guarantee, we undertake at our discretion to repair or replace the defective goods. We will not consider supplementary claims, especially for
reimbursement of costs relating to the defect (e.g. installation / removal costs) and
compensation for consequent damages unless they are allowed by statute. This does
not affect claims based on legal regulations, especially according to product liability
law.
Guarantee requirements
The purchaser is required to make the guarantee claim in writing, and must enclose
original proof of purchase (e.g. invoice, receipt, delivery note) and this guarantee
card. He must send the defective goods to us at his own cost, using the address
stated above.
The purchaser should state the material defect or manufacturing fault, or the symptoms of the fault, in as accurate a manner as possible, so that we can check if our
guarantee obligation is applicable.
The goods are transported from the consumer to us and from us to the consumer at
the risk of the consumer.
Duration of validity
This declaration only applies to claims made to us during the claim period as stated
in this declaration. The claim period is 24 months from the date of purchase of the
product by the consumer from a dealer in the Federal Republic of Germany (date of
purchase). If a defect arises after the end of the claim period, or if the evidence or
documents required according to this declaration in order to make the claim valid are
not presented until after this period, then the consumer forfeits any rights or claims
from this declaration.
Limitation by lapse of time
If we do not acknowledge the validity of a claim based on this declaration within the
claim period, all claims based on this declaration are barred by the statute of limita-

tions after six months from the time of implementation; however, this cannot occur
before the end of the claim period.
Applicable law
This declaration, and the claims, rights and obligations arising from it, are based exclusively on the pertinent German Law, without the norms of international private law,
and excluding UN retail law.
The following points are important and must be observed at all times:
• Before you fly the model, check that the radio control system is working reliably,
and that all connections are secure.
• If you intend to use dry cells as a power supply, please note that they must never
be recharged. Only cells marked as ‘rechargeable’ are safe to re-charge.
• The batteries must be charged and the range of the radio control system must be
checked before you operate the model. In particular, the radio control system batteries must be charged before each session and checked before every flight.
• Ensure that the channel you intend to use is not already in use by other model-
lers. Never fly the model if you are not certain that your channel is free.
• Read and observe the instructions and recommendations provided by the manu-
facturer of your radio control system and accessory components.
• Ensure that the servos are not mechanically obstructed at any point in their
travel.
• Dry cells and rechargeable batteries must never be short-circuited.
• Remove all batteries from the model prior to transporting and storing it.
• Do not subject the model to dirty or cold conditions, or high levels of humidity or
heat.
• Secure the model and your RC equipment carefully when transporting them.
They may be seriously damaged if they are free to slide about.
Pre-flight checks
Check that the radio control system is working correctly and at full range before every
flight: fit the transmitter aerial and extend it fully, then switch on the transmitter and
the receiving system. Walk away from the model, and check that all the control surfaces work smoothly and immediately at an appropriate distance, and deflect in the
correct ‘sense’ (direction) relative to the stick movements.
Repeat the check with the engine running, while a friend holds the model securely for
you.
If you are a relative beginner to model flying, we recommend that you enlist the aid of
an experienced model pilot to help you check and test-fly the model.
Care and maintenance
• Clean the model carefully after every flight, and remove any dirt from the propel-
ler. Clean the aeroplane and the RC components using suitable cleaning agents
only. Ask your model shop for information if you are not sure.
• If the model is not to be operated for a considerable time it is important to clean
and re-lubricate all the moving parts.
