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 model 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 built-up
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 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.
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 and fit the
screw.
Safety notes and warnings relating to model
aircraft powered by glowplug motors
• 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 or her 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. We do not permit this model’s use in any way except as a model
aircraft.
• 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 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 (CG) 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 and motor.
• 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 a motor 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 motors produce lethal carbon monoxide gas just like
full-size engines.
• Motors 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 motor 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

GRAUPNER GmbH & Co. KG D-73230 KIRCHHEIM/TECK GERMANY

especially when carrying out adjustments - wear protective gloves. Hot
engines can even start a fire under certain circumstances.
• When the motor 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 motor 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 motors are usually started with the help of an electric starter which
should be fitted with the appropriate adaptor where necessary. With fixed-
wing 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 motors are very noisy, producing a sound level much higher than
85 dB (A), which implies that you should wear ear defenders. Never run a
motor without the silencer fitted. Even with a silencer, model engines can
easily disturb your neighbours. Don’t run motors when other people expect
peace and quiet.
• If you start your motor 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 glowplug clip and the glow 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 motor 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 motor, 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 can stop your motor 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 motor 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. 8034.01, and
contains a summary of all these rules. Your local model shop should have a
copy which you can read. For models powered by internal-combustion
engines it is essential to obtain the landowner’s permission before flying.
There are also Post Office regulations concerning your radio control system,
and these must be observed.
• 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 incompetent or incorrect
use and operation of our products, 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, damage 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 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.
Before you operate the model for the first time, please check that your private third-party
liability insurance policy covers you for the operation of models of this type. If you are
not sure, take out a special policy designed to cover modelling risks.
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.

• Before you fly the model, check that the radio control system is working reliably, and
that all connections are secure.
• If you use dry cells as an energy source, please note that you must never attempt to
recharge them. Only batteries marked specifically as “rechargeable” may be
recharged safely.
• 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 fully charged before each session and checked before each flight.
• Ensure that the channel you intend to use is not already in use by other modellers.
Never fly the model if you are not certain that your channel is free.
• Read and observe the instructions and recommendations provided by the
manufacturer 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 motor 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 propeller.
Clean the model and RC components using suitable cleaning agents only. Ask your
model shop for information.
• If the model is not to be operated for a considerable time it is important to clean and
re-lubricate all the moving parts.
Notes on completing the model
• Before building the model it is important that you read the instructions right through to
the end.
• Tools can be dangerous; please be aware of the hazards involved in using them.
• Use cable of adequate cross-section, capable of carrying the currents which will flow
when the model is flying.
• Deploy the receiver aerial as far away from high-current cables as possible (at least
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 to the fuselage it is essential to roughen the surfaces
with fine abrasive paper and de-grease them with acetone or similar solvent,

Radio control system
For this model you require at least a six-channel RC system with eight servos. The
transmitter should also feature a servo reverse facility.
We particularly recommend mc-22 to mc-24 computer systems. The model is designed
for standard-size servos.
We recommend the following receiver battery: GMVIS GP 3300 NiMH, Order No.
2573.4, which should be properly maintained before and after each flying session.
Please remember that the pack needs to be cycled (charged and discharged) several
times before it reaches full rated capacity.
For connecting the aileron, landing flap and retract servos to the receiver you will need
five suppressor filters, Order No. 1040, or a folding ferrite ring, Order No. 98516.1,
together with five extension leads, Order No. 3935.11. The two aileron servo leads
should be extended using extension leads, Order No. 3935.32, the two flap servo leads
with Order No. 3935.11.
Foam padding for the receiver and receiver battery is included in the kit.
The model is designed for standard-sized servos.

Assembling the Focke Wulf 190 D
Don’t start building the model until you have read right through the building instructions
and are familiar with all the model’s components. If you are not satisfied with any part,
inform your supplier before you start work on the model.
Completing the fuselage
Locate the openings in the fuselage sides for the tailplane panels, and the joiner holes in
the tailplane root ribs, and melt the film away using the tip of a hot soldering iron.
Remove all the covering film from the tailplane root ribs in order to obtain sound glued
joints.
Check the fit of the tailplane panels by sliding the aluminium tube through the fuselage
and fitting both tailplane panels onto it.
When you are satisfied, glue the tailplane panels to the aluminium tube and to the
fuselage.
Tape the tailplane in place while the glue is hardening.
Drill blind holes at the marked points in both elevator panels for the horns; they should
be 6 mm Ø diameter and 8 mm deep.
Tip: you can avoid drilling too deep by clamping a collet on the bit at the required depth.
The elevators can now be attached to the tailplane using the hinges provided. This is
done by gluing the hinges half-way into the elevators and allowing the glue to set. The
projecting hinges can then be glued in the slots in the tailplane.
When the adhesive has cured, glue the horn sockets in the holes in the elevator panels,
after removing a disc of covering film the size of the socket flange. To mark the
diameter, fit the socket in the hole and slit the film round it using a sharp balsa knife.
Tip: a good method of cutting out accurate discs of film is to take a piece of brass tube
whose I.D. (internal diameter) is the same as the O.D. (outside diameter) of the socket,
and sharpen the edge to form a hole-punch. Rotate the tube gently to cut the film.
The horns can now be glued in place permanently: fit the M3 stud into the socket as far
as it will go, and secure it with an M3 lock-nut. Set the linkage lugs to the correct height,
then cut off the excess stud length and file it back flush with the lug. The correct height
of the horns is dictated by the level of the pushrods where they exit the fuselage. With
the elevators at neutral, the pushrods should run in a straight line to the linkage hole.
Obviously it is essential to set both elevator horns to the same height.

Attach the rudder to the fin by gluing the hinges in place, as described for the elevators,
and complete the linkage in the same way.
The next step is to install the elevator and rudder servos in the mounting plate in the
fuselage, as shown in the following photos.
Drill out the linkage holes in the servo output arms to 1.8 mm Ø in order to accept the
pushrods.
Set the control surfaces and servos to centre, and mark the point on the pushrods where
they cross the servo output arms. Bend the pushrods at right-angles at the marked
points using a pair of flat pliers, and remove excess rod length; they should project
beyond the retainer clips by about 1.5 mm.
Fit the retainer clips and push them onto the pushrods from the side.
Assembling and installing the fueltank
Cut a piece of silicone fuel tubing and push it onto the fueltank clunk weight. Push the
free end of the fuel tubing onto one of the tubes in the fueltank stopper, and check that
the clunk will be able to move freely inside the tank without binding or jamming when
the stopper is in place. Use a match or a heat-gun to soften the projecting plastic tubes,
and bend them to the shape shown in the illustration. Check that one pipe points down
(filler line) and one up (vent line; this is the overflow when you are filling the tank).
Push the stopper into the tank and tighten the cross-point clamping screw. Ensure that
the screw is tight enough to seal the fueltank completely. You can check this by holding
the tank under water: blow into the tubes and watch carefully: if bubbles rise, there is a
leak which must be sealed.
Cut three pieces of silicone fuel tubing and push them onto the tubes where they exit the
fueltank.
Mark the fuel lines using a felt-tip pen or coloured tape to indicate which is the fuel feed,
the overflow and the filler.
Fit the fueltank through the wing saddle and into the tank compartment in the fuselage,
slipping the three silicone fuel tubes through the hole in the nose bulkhead.
Fit a rubber band between the projecting tongues of the bulkhead behind the fueltank;
this pulls the tank forward, and ensures that it cannot shift in flight.
If you intend to install a petrol engine, the fueltank stopper supplied in the kit must be
replaced with a petrol-resistant equivalent, e.g. Order No. 133. The silicone fuel tubing
must also be replaced with a type suitable for petrol, e.g. Order No. 1325.2.
Installing the glow motor
The instructions and photos show the installation of an OS MAX FS 120 four-stroke
motor, but the procedure is basically the same if you fit a different OS MAX power plant.
Fix the motor mount to the nose bulkhead using the screws supplied; remember to
secure each screw with a drop of thread-lock fluid.
The next step is to screw the glow motor to the motor mount. Note that the distance
between the nose bulkhead and the front face of the propeller driver should be around
145 mm. With the motor in this position, mark the location of the holes in the mounting
lugs on the mount arms: a good method is to use a drill bit the same diameter as the
holes in the mounting lugs, and twist it lightly to make a mark. Remove the motor, drill
the holes for the retaining screws at the marked points, and fix the motor to the mount.

The throttle pushrod can now be fitted, but first the throttle arm has to be removed from
the carburettor. Connect the pre-formed end (Z-bend) of the throttle pushrod to the
outermost hole in the throttle arm. Slip the pushrod into the appropriate guide tube, and
fit this assembly through the hole in the nose bulkhead from the front. Fit the throttle arm
on the shaft of the throttle barrel in such a way that it is parallel to the carburettor
centreline when the throttle barrel is exactly half-open.
Attach the swivel pushrod connector to the output arm of the throttle servo.
Apply a drop of UHU thread-lock fluid to the nuts to prevent them working loose. Ensure
that the pushrod connector rotates smoothly, but without significant slop; take care not
to jam it with the thread-lock fluid.
Install the throttle servo in the servo plate in the fuselage, at the same time fitting the
throttle pushrod through the swivel connector. Glue the throttle guide tube to the
fuselage side at a point about 150 mm from the throttle servo.
Screw a silencer support bracket, e.g. Order No. 607, to the nose bulkhead, as shown in
the photo.
The silencer itself is attached to the bracket using binding wire or a metal clamp.
Prepare the cowl by cutting and filing out the openings for the cylinder head, needle
valve etc., and drilling the holes required. The cowl can be fixed to the model using
either of two methods: either using externally fitted screws or concealed fixings, fitted
from the front.
For the first version hardwood blocks have to be glued in the recesses in the nose
bulkhead; the cowl retaining screws are fitted into these blocks.
For the concealed version the nose bulkhead is glued in the cowl, which is then fixed to
the main bulkhead from the front using four cheesehead screws. In either case it is
important to ensure that the motor crankshaft exits the cowl in the centre of the opening,
and that there is about 10 mm clearance between the cowl and the propeller driver.
Assemble the tailwheel unit as shown in the photos, and screw it to the fuselage and the
rudder. Drill pilot-holes for the retaining screws beforehand.
The final stage involving the fuselage is to fit the dummy exhaust pipes and turbo-
charger. Use your fingertip to locate the opening for the dummy turbo-charger in the left-
hand fuselage side, and melt away the covering film over an area slightly smaller than
the opening using a hot soldering iron.
Glue the dummy turbo-charger to the fuselage.
The dummy exhaust pipes are glued to both sides of the fuselage, as shown in the
photo.
The ON / OFF switch should be fitted in the left-hand fuselage side. Cut an opening in
the fuselage side to suit the switch, and install it using the screws provided.

epoxy, keeping the marked line just visible. Distribute the excess glue over the face of
the root rib. We recommend the use of a slow-setting adhesive for this stage, e.g. UHU
coll or UHU plus endfest.
Apply plenty of epoxy to the inside of the joiner socket of the other wing panel, apply
more adhesive to the root rib, and push the wings together. Wipe away excess glue,
then line up the root ribs carefully and tape the wings together while the glue is
hardening.
When the joint has cured, use your fingertips to locate the openings in the wing for the
undercarriage, and melt away the excess film using a hot soldering iron. You have the
option of installing a fixed undercarriage or a retractable version.
If you opt for retracts, the mechanical units must first be adjusted, i.e. the end-points
have to be set correctly to suit the model.
Slip the retract pushrods through the openings in the retract units, and connect them to
the actuating tongues. Position the retract units in the recesses, mark and drill the holes
for the retaining screws, and fix the units in place using the screws provided.
Fit the wheels on the axles and attach the axles to the wire undercarriage legs. Check
that the wheels are located exactly in the centre of the wing recesses when retracted.
The wheels are attached to the axles of the retract units using collets and self-locking
nuts; two collets are used for each wheel of the fixed undercarriage.
The next step is to mark the exact length of the retractable wheel legs.
Remove the wheel legs from the retract units and cut them to length; a cut-off disc in a
mini-drill is best for this. Note that a small flat section must be filed or ground into the
wheel legs at the appropriate point to accept the axle clamping screws. The wheels
should be installed with about two degrees of toe-in.
If you are fitting a fixed undercarriage, naturally you should only melt away the
film over the channel for the wire undercarriage units - not the area for the retract
unit.
Fixed undercarriage: insert the undercarriage units in the channels and secure them with
the plastic saddle clamps. Drill pilot-holes for the retaining screws beforehand.
Press the rubber grommets and tubular spacers into the mounting lugs of the retract
servo, and screw it to the servo plate.
Two holes have to be drilled in the large servo output disc for the linkage to the two
retract units; the holes should be 25 mm apart.
Mount swivel pushrod connectors in the two holes in the output disc, ensuring that they
rotate smoothly, but without significant play. The output disc should be fitted on the
retract servo in such a position that the two swivel pushrod connectors are opposite
each other at the “retracted” end-point of the servo. Retract the wheels by moving the
pushrods to their end-points, then tighten the grubscrews to secure the pushrods in the
swivel connectors.
Apply a drop of UHU thread-lock fluid to the two grubscrews to prevent them working
loose.

Install the aileron and flap horns as described for the elevator and rudder: mark the
correct position, drill the blind holes to the correct depth, and glue them in place.
The aileron and flap servos can now be prepared for installation while the glue is
hardening.
Press the rubber grommets and brass tubular spacers into the servo mounting lugs; the
spacers act as a template when marking and drilling the holes in the servo mounts for
the retaining screws. Drill 1.5 mm Ø pilot-holes and install the servos using the screws
supplied with them.
Extend the servo leads using the appropriate extension leads, and secure the
connections with a drop of glue or a piece of heat-shrink sleeve. Fit an M2 locknut and
an M2 clevis on each threaded pushrod.
Cut down the servo output arms as shown in the photo, then press them onto the servo
output shafts and fit the retaining screws. Ensure that the outermost linkage hole is the
correct diameter for the clevis pin.
Set the servos to centre (neutral) before fitting the output arms on them.
The servos can now be installed in the wing, but first the recesses must be opened up.
To ensure that the decals line up correctly, the covering film should not be melted away
in the usual way, but carefully cut out along the outside edge using a sharp balsa knife.
The film can then be stuck down to the Servo-Locks (servo mounts).
Screw the Servo-Locks in the recesses in the wing, and route the servo extension leads
out of the holes adjacent to the root ribs.
Connect the clevises on the pushrods to the outermost holes in the servo output arms.
Set the servos and control surfaces to centre, and mark the point on the pushrods where
they cross the horns. Bend the pushrods at right-angles at the marked point and snip off
excess rod material. Fit the retaining clips and snap them over the pushrods.
The areas of the wing where the retaining screws are fitted should now be reinforced by
gluing the plywood spreader plates over the holes on the underside.
Remove the covering film from the underside of the wing at the spreader plate location,
cutting slightly inside the line, and glue the plates in place. Fit the wing on the fuselage
and tighten the retaining screws moderately to hold the spreader plates in position while
the glue is hardening.
Assembling the FOCKE WULF 190 D
To make it easier to connect the aileron, flap and retract servos to the receiver, we
recommend that you connect a 100 mm extension lead to each of the appropriate
receiver sockets.
Connect the aileron, flap and retract servos to the extension leads, then attach the wing
to the fuselage as follows: engage the hardwood dowels in the holes in the fuselage
former, then fit the two countersunk retaining screws at the trailing edge. Tighten the
screws just to the point where the wing is held securely on the fuselage, and cannot
shift.

Balancing the FOCKE WULF 190 D
Support the assembled model (fueltank empty) under both wing roots at a point about
115 mm to 125 mm aft of the wing root leading edge; it is best to hold the model inverted
for this procedure. If the CG position is correct, the model will hang level, with the nose
inclined slightly down. If necessary, re-position the receiver battery to obtain the correct
balance, or glue lead ballast to the nose or tail. All the control surfaces must be exactly
at centre when the transmitter sticks and trims are in the neutral position; check this
before the first flight.
Control surface travels
Ailerons 17 mm up, 17 mm down
Elevators 18 mm up, 18 mm down
Rudder 35 mm right, 35 mm left
Landing flaps take-off: 12 mm
landing: 35 mm
We recommend that you set 35% exponential on the ailerons, and 50% on the elevator.
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: elevators 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 motor should run to the full-throttle
position, i.e. the carburettor barrel should be fully open. The landing flaps can be
assigned to a slider or a three-position switch. We recommend a two-position switch for
the retractable undercarriage.
We wish you every success and many enjoyable flights with your FOCKE WULF 190 D.
