Caution: This model is not a toy!
If you do not have experience with such motorised models, please ask experienced
model flyers for help. If the model is operated without the proper knowledge, injuries
can result. Think of your health and safety!

Important! Before you start the assembly!
Even if you have already built lots of RC models, read these instructions through
carefully and check the parts in the kit for completeness. A lot of effort was made to
keep things as simple as possible without neglecting safety.

Note on the covering sheet
Because of strong changes in the weather (temperature, humidity, et cetera), small
creases can appear in the covering sheet. In rare cases, the components can even
be warped. This lies in the nature of wood construction with covering sheet. This can
be corrected as follows using a hair dryer like those available to model builders.
Creases: Blow hot air over the area and rub with a soft cloth.
Warped area: Gently twist the area against the direction of warping and smooth

it out again using hot air.

Caution! Never use more heat than is absolutely necessary. If the iron is too hot, the
covering sheet will melt and holes will form.

The extensively pre-fabricated model can be built in a very short time. However, the
remaining steps are important and have to be carried out with care. Doing this work
properly determines whether the model will have the prescribed rigidity and flight
characteristics; so please work slowly and precisely!

When putting screws into wood, apply a little casein glue to keep them from
loosening: Squirt casein glue into the drill hole and screw in the screw.

6865

• Before assembling the model, it is essential to read the construction diagram and
the instructions all the way through. When using tools, be aware of the possible
dangers.

• Use only suitable cables that are adequate for the electrical currents that occur
during operation.

• Set up the receiver aerial as far as possible away from the cables carrying the
operating current (at least 3 cm).

• Clean residual grease from all connections that are to be glued. This could be
done, for example, through sanding and using a non-relubricating cleaning
solution. The same goes for the surfaces to be painted, in order to make sure that
the paint sticks. Before gluing parts, always roughen the corresponding surfaces
(especially for GFR fuselages) carefully with fine sandpaper and de-grease them
thoroughly, for example with acetone. Otherwise, adequate adhesion is not
assured.

Assembling the JODEL ROBIN DR 400/180

Wings with undercarriage and tailplane

Do not begin the assembly until you have familiarised yourself with the components
and the individual construction stages. If you are not satisfied with any component,
report it to your retailer before you start the construction process.

Using sandpaper or sanding block, sand the control horns on the surfaces to be
glued in order to achieve an adequate connection when gluing.

As seen in the photos, remove the covering from the slots for the GRP control horns,
put a dab of glue into the slot, and push the control horn in until it stops.

Wipe off any excess glue.

Until the glue hardens, the servos
are installed in the corresponding mounts and fastened into the wing or tailplane.

Extend the servo cables using the corresponding extension cable and make sure
they can not come loose, for example with a piece of heat-shrink tubing or a drop of
fast-setting glue. Using the RC system, bring the servos into centre position and
install the servo levers.

Fasten the servo to the attachment block using the screws included with the servos.
To do so, insert the rubber grommets with the brass hollow rivets, collar downward,
into the servo flange. For drilling Ø 1.5 mm holes for the screws, the hollow rivets can
be used as a drilling template. To make it easier to push them in,
the hollow rivets can be placed onto a screwdriver of the proper size.

Now the servo cables are pulled into the wing halves and tailplane halves using a
thread. Just behind the connector, tie the thread to the cable and pull it in so that it
comes out the wing root.
With servo and rudder in neutral position, screw together the lengths of the rods for
the ailerons, landing flaps, and elevators, adjust them; then use thread lock fluid
(such as UHU schraubensicher) and lock nuts to secure them against loosening.

As shown in the photo, secure the hinges for the landing flaps using heat-shrink
tubing.

On the underside of the wings, there are markings indicating where the flap hinges
can be screwed in. Make sure that the axes of rotation of the hinges are all the same
distance from the trailing edge of the wing.
As shown in the photo at the left, use one screw to

fix the hinges in place; then use an engineer's square or geometric protractor for
alignment with the trailing edge, and fasten the hinges with two more screws. Now
push the landing flaps up against the wings and tape them in place temporarily; align
them, and fasten them with screws.
Screw the pushrods together as shown in the following photos.

In the next step, use your fingers to feel for the slot for the landing gear wire, and
melt it free with a hot soldering iron.

Now place the leg of the undercarriage into the slot to mark the attachment points of
the two tabs and the wheel fairing support block.

Drill pilot-holes in the wings for the retaining screws; then screw the tabs and the
wheel fairing support block to the wing.

For the wire undercarriage units you will need to file away the inside of the two
fairings a bit. When installing the fairings, make sure that the wheel covers 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. Loosen the grubscrew at the front of the shock absorbing strut, loosen, and
push the wheel axle to the other side. Re-tighten the grubscrew.

The wheels and wheel fairings must be aligned exactly parallel with the fuselage
centreline.

The final work on the wing is to install the landing searchlight.
As shown in the following photographs, fit the two LEDs in the white plastic holder
and secure them with a little UHU Power all-purpose adhesive.

Trim the outside edges of the plastic holder so that it fits in the recess in the wing.
Route the connecting leads of the two diodes to the root rib using a piece of thread,
and run they out of the drilled access hole. The plastic holder can now be glued in

using UHU Power all-purpose adhesive. Fix the glazing to the wing using clear
adhesive tape.

Fuselage with tailplane, vertical stabiliser, and nose gear

The vertical stabiliser can either be glued permanently to the fuselage or fastened
removably using four screws.
Only the fastening of the vertical stabiliser using screws is described.
Before putting in the screws, the two extension cables for the two elevator servos
must be pulled into the fuselage.

Use the Ø 12 mm aluminium tube to put the horizontal stabiliser onto the fuselage to
test the fit; the two extension cables must be routed through the openings of the
horizontal stabiliser on the right and left.

We reserve the right to introduce modifications. Not liable for printing errors!

11/2011

10

The two halves of the tailplane must be attached to the fuselage using the Ø 12 mm
aluminium tube and four M3x16 Allen screws each.

Now the rudder is fastened to the horizontal stabiliser using steel wire. Assemble the
pull cables as shown in the photo.

Then attach the rudder servo to the servo plate at the front of the fuselage.
As shown in the photo, install the pull cables to the servo lever and adjust them so

that the rudder is in the centre position when the servo is in the centre position.

As shown in the photo, fix the fairing support block to the nose gear using an M4
Allen screw and nut.

11/2011

11

Fix the nose gear in the brackets by tightening the screw in the collet. Assemble the
pull cables as shown in the photo.

Here too, make sure that the nose gear is exactly in the neutral position when the
servo is in the centre position. Later the nose gear steering servo and the rudder
servo can be connected to the same receiver socket either using a Y-lead or via a
mixer at the transmitter.
As shown in the photos, the wheel fairing is attached to the support block using four
self-tapping screws.
The nosewheel can now be fitted onto the axle and secured using two collets, as
already described for the main undercarriage.

As with the ailerons and landing flaps, each of the rudder pushrods consists of two
M3 clevises and nuts and one threaded rod. The length of the two rods must be
adjusted so that the elevators are at the centre position when the servo is in centre
position. Before screwing in the two elevator servos, the connecting cables must be
extended using suitable extension cables.

Screw the aero-tow mechanism into the hole just behind the canopy, and apply UHU
thread-lock fluid to prevent the coupling and nut from working loose.
The aluminium part must be shortened enough so that the clevis can move freely;
adjust the rods accordingly.

It is best to operate the aero-tow release mechanism using a momentary switch
mounted on the joystick. The servo travel must be set accordingly.

Installing the tank and motor
Assembling and installing the fuel tank

Slip a piece of plastic tubing (about 160 mm long) onto the fuel tank clunk pick-up.
Push the free end of the fuel tubing onto one of the tubes in the fuel tank stopper so
that the pick-up will be able to move freely inside the tank later on without binding or
jamming when the stopper is in place. Use a heat-gun or lighter to gently heat the free
plastic tubes so that they can be bent easily. One tube should face down and will be
used later to fill the tank; the other one points upward and will serve later as the
overflow when the tank is filled. Extend each of the two tubes with a piece of fuel
tubing so that they extend to the top and bottom of the tank, respectively.
Now push the tank stopper over the throat of the fuel tank, and tighten the Philips-head
screw to fasten the stopper in place. It is important to tighten the screw so that the tank
is completely sealed. This can be checked by holding the tank under water. Hold it
under water and blow air into it. If the tank is sealed, there will be no air bubbles.

Connect a further length of fuel tubing to each stub tube projecting from the fuel tank.
Mark the silicone tubes with a felt marker to show which of them runs to the motor, the
overflow, and the filler.

11/2011

13

Once the tank is pre-assembled in this way, it is fastened to the attachment block as
shown in the photo.

Push the fuel tank into the fuselage so that the three silicone tubes stick out through
the drill hole in the bulkhead.

The tube from the clunk is then connected to the carburettor, while the overflow is run
downward. The fuel filler tube can later be routed out through a drill hole in the motor
bonnet. After filling, it should be sealed with a plug.
The attachment block is fastened with two screws.

The throttle servo must be installed using the bracket as shown in the photo.
Depending on the motor used, the servo is installed to right or left of the tank.

Installing the motor

This section describes the installation of the OS MAX GT 55, but the procedure is the
same for other engines.
Four holes for the rubber damping elements have to be drilled into the firewall to
match the particular engine.

We reserve the right to introduce modifications. Not liable for printing errors!

11/2011

14

The centre of the motor is marked on the firewall. Drill Ø 10 mm holes to match the
attachment holes for the engine.
Now push the rubber dampers into the four holes, and attach the engine using four
Allen screws, stud bolts, washers, and nuts. Tighten the Allen screws only to the
point that there is still a damping effect.

The throttle rod is adjusted so that the carburettor is half open when the servo is in
centre position. The servo travel must be adjusted so that the engine stops when the
throttle stick and trim are at the full back position.
The silencer is attached using the brass strips supplied, which are bent and drilled
according to the dimensions shown in the photo.

Attach the silencer to the motor using the manifold, the Teflon hose, and the spring
clamps. With these parts in place, the attachment points for the two aluminium
brackets can be marked on the fuselage by screwing the two attachment brackets to
the silencer; drill the Ø 4.2 mm holes and attach the brackets to the fuselage using
M4 Allen bolts and captive nuts.

Now, the silencer can be attached to the

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

11/2011

15

aluminium brackets, and, together with the manifold, can be bolted to the engine; a
drop of UHU thread-lock fluid should be applied to each bolt and nut to prevent them
working loose.

To fit the motor used, it is necessary to cut or file out openings in the engine bonnet
for the silencer exhaust pipe, spark plug, et cetera. Position the engine bonnet on the
fuselage in such a way that the clearance is about 2 mm between the spinner base
plate and the front edge of the bonnet.

To attach the engine bonnet to the fuselage, the four attachment points also have to
be marked on the engine bonnet. To do so, cut four strips of scrap wood and drill a Ø
3 mm hole in each one as shown in the photo.

We reserve the right to introduce modifications. Not liable for printing errors!

11/2011

16

Now each strip is fastened to the fuselage using an M3 Allen screw and taped in
place as shown in the photo.

Unscrew the Allen screws, then push up the engine bonnet so that it moves under
the strips and the spinner base plate is about 1.5-2 mm from the engine bonnet. In
this position, mark the four attachment points on the engine bonnet.

11/2011

17

The engine bonnet is attached with four Allen screws as shown in the photos.

Cockpit canopy

Glue the seat backs and pilot figure in the proper positions as shown in the following
photos.

The parts should be affixed using double-sided tape, such as Order No. 2904.

11/2011

18

The cockpit canopy is attached to the frame using small pan-head self-tapping
screws. A strip of tape all around has proven to be a good way to ensure that the
cockpit canopy fits the frame uniformly.
The final work on the model consists of fitting and gluing the navigation lights, hatch
covers, and aerials and affixing the decals and lettering.

Balancing the Jodel ROBIN DR 400/180

The completely equipped model, with the fuel tank empty, should balance level when
supported at a point about 140 - 150 mm aft of the leading edge of the wing, ideally
in inverted flight position. If the centre of gravity is correct, the model should balance
out horizontally or with the nose pointing slightly downward. If necessary, adjust the
centre of gravity by shifting the position of the receiver batteries or screwing on trim
weights. Before flying the aircraft, set the transmitter trims to centre and ensure that
all the control surfaces are also exactly centred (in neutral position).

Rudder deflection for normal flying

Ailerons 30 mm up and 10 mm down
Elevators 25 mm up and down
Rudder 45 mm left and right
Landing flaps Take-off 15 mm down
Landing 60 mm down
We recommend that you set exponential values of 30% at the transmitter.

Assembling the Jodel Robin 400/180

Attach the two halves of the tailplane to the fuselage using the aluminium tube.
Connect the servo cables to the extension cables coming from the fuselage; secure
with Order No. 3506. Push the halves of the tailplane all the way onto the fuselage
and fasten each with four Allen screws.
Use the aluminium tubes to place the wing halves onto the fuselage. Stick the servo
connector cable together with the extension cable from the receiver and secure with
Order No. 35060. Slide the wing halves completely onto the fuselage and connect

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

19

each to the fuselage using two plastic screws. Only tighten the screws enough to
bring the two wing halves together with the root rib.

Important:

When assembling the rods, always take care to ensure that they move freely and can
move through their entire controllable path - including trim travel - and are not
mechanically impeded.
When the joystick moves to the right, the rudder and nose gear must turn to the right
(left stick/left rudder). When the elevator stick is pulled back, toward your stomach,
the elevators must deflect upward (stick forward = elevators down). If the aileron stick
is moved to the right, the right aileron should move upward; the left aileron
downward. When the throttle stick is pushed forward, the motor must run at full
power; if the throttle stick and trim are moved back to their end-points, the engine
must stop. If the trim travel is moved all the way back, the motor must stop. The
landing flaps are best activated via a three-position switch.
All that remains is to wish you many hours of happy flying your JODEL ROBIN DR
400/180.

Safety notes and warnings

Regarding motorized aircraft models with internal combustion engines

• Before you first attempt to fly the model, it is essential to carefully read all
the operating and assembly instructions.

• These safety notes are part of these instructions and must be stored
carefully with the operating instructions and, if the model is passed on to
others, they must also be passed on to the next user.

• Motorised models are very demanding and dangerous objects and require
that the user have great expertise, skill, and a sense of responsibility.

• Motorised models are not suitable for persons under 18 years of age.

• They may be operated only under the instruction and supervision of an

adult who is familiar with the attendant hazards.

• 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 aircraft models may be used only for the purpose intended
by the manufacturer; meaning not as a sporting device designed to carry
people. Any other use is forbidden.

• A model can only work properly and fulfil your expectations if it is built or
assembled with the greatest of care and in accordance with the assembly
instructions. Independent changes in design or materials are not permitted.
To avoid injuring people and damaging property, it is essential to be careful
and thoughtful when operating your model. Nobody would climb into a full­size glider and attempt to fly it without undergoing training beforehand.
Model flying is also something that has to be learned! We suggest that you
ask an experienced model flyer for help, or join a model club or model flight
training school. Your local model shop and the specialist magazines are
excellent sources of information.

• Always observe the information on the centre of gravity and on control
surface deflection! The model must be adjusted accordingly.

• Radio control system: Make sure the frequency used is vacant. Do not
switch on until you are sure! Check the RC system frequently; it too is
subject to wear. Radio interference caused by unknown sources can occur
at any time without warning. Your model will then be uncontrollable and
completely unpredictable. Never leave your radio control system
unattended, as another person might pick it up and try to use it. To ensure
proper operation of your RC system, make sure that the batteries are kept
fully charged.

• Do not ignore warnings! They refer to materials and situations, which, if
ignored, can - in extreme cases - result in fatal injury or permanent damage.

• You alone are responsible for the safe operation of your model and motor.

• Questions regarding the safe operation of model and motor can be

answered by your retailer.

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

• Propellers and other rotating parts that are powered by a motor pose a
constant risk of injury. Do not touch them with any part of your body! For
example, a propeller spinning at high speed cut off a finger!

• Always 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 and with
great energy, hitting you or a third party. Make sure that no other object can
come into contact with the rotating propeller.

• Be careful with loose clothing, such as scarves, loose shirts, et cetera: They
can be sucked in by the propeller stream and get in the way of the propeller
itself.

• If there are passers-by or spectators at your flying site, make sure that they
are aware of the dangers inherent in your activity before you start the
motor, and insist that they keep a safe distance away (at least 5 m).

• Model aircraft may be flown only at "normal" outside temperatures,
meaning in a range of - 5º C to + 35º C; more extreme temperatures could
lead to changes, such as battery capacity and material characteristics, et
cetera.

• Model fuel is poisonous! Do not let it come into contact with eyes or mouth!
Store only in clearly marked containers out of the reach of children.

• Never run the motor in closed rooms, such as basement, garage, et cetera.
Model motors also produce deadly carbon monoxide gas.

• Operate only outdoors!

• Adhesives and paints contain materials which may be hazardous to health

under certain circumstances. You should therefore observe the notes and
warnings supplied by the manufacturers of these materials.

• Model fuel is highly flammable and combustible; keep away from open
flames, excessive heat, and any sources of sparks or other things that
could lead to ignition. Do not smoke in the direct vicinity of fuel or fuel
fumes.

• During operation, a model motor develops a great deal of heat. Motor and
shock absorbers are therefore very hot during operations and for a while
afterwards. Touching them can result in serious burns. Careful when
making adjustments! Wear protective gloves! In extreme cases, even fires
can be caused.

• While operating the motor, not only poisonous and hot exhaust emanates
from the exhaust pipe but also very hot liquid combustion residue, which
can result in burns.

• After operation, remove residual fuel from the tank and motor.

• Before and after you operate your model, always carefully check it and

everything attached to it (such as propeller, rudder linkages, rudders, et
cetera) for possible damage. If you find a fault, do not fly the model until
you have corrected it.

• The motor is started with an electric starter, which may be equipped with an
adapter that fits the model. As an alternative start aid for fixed-wing models,
a wooden dowel with a piece of watering hose attached can be used, for
example.

• During operation, model motors may develop noise far greater than 85 dB
(A); always wear protection for your ears. Never start motors without a
silencer. However, even with a silencer, model motors can disturb
neighbours. Do not run motors when people expect peace and quiet.

• If the propeller is turning while the model is standing on sandy ground, for
instance, the propeller can suck up sand and dust and hurl it around, and it
could get in people's eyes. Wear protective goggles!

• Take care that the spark plug clip and the lead can not get tangled in the
turning 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!

• Always keep an adequate supply of fuel in the tank. Never continue to fly
the model until all the fuel is used up.

• Never fly directly over people.

• Never fly directly towards people.

• Make sure to keep a safe distance from residential areas: at least 1.5 km “as

the crow flies”. It is always best to join a club and fly at the approved model
flying site. Always keep well clear of high-tension overhead cables.

• Whenever working on the engine, make sure that you have secure footing,
and always hold the model securely.

• When starting and landing, the take-off and landing strips should be kept
free of unauthorised people and movable obstacles.

• The model aircraft must be kept constantly in sight during the entire flight. It
must always give way to manned aircraft.

• Never operate your aircraft from public roads, squares, squares, school
playgrounds, parks, or sports grounds, et cetera, and ensure that you are
always in full control of the model.

• To ensure that you can stop your engine at any time, the throttle must be
adjusted so that the carburettor barrel closes completely when the throttle
stick and trim are moved to their end points. If this does not work, pinch the
fuel line between your fingers or pull off the connecting tube to the tank.
Never try to stop the engine by grasping the flywheel, propeller, or spinner!

• All model fliers should take care to ensure that the public safety, especially
that of people and property, as well as orderly flying operations, are not
endangered or disturbed.

• In legal terms, model aircraft are classed as aircraft and as such are subject
to legal regulations and restrictions that must be observed.

• Our brochure “Modellflugrecht, Paragrafen and mehr” (Model Aviation Law,
Legal Requirements and more), Order No. 8034.02 contains a summary of
all these rules, and your local model shop should also have a copy which
you can read. Models powered by internal combustion engines may only be
flown with the landowner’s permission, and insurance is mandatory. There
are also regulations concerning your radio control system that must be
observed.

reasonable care, model flying is a highly creative, instructive, and relaxing
pastime.

• The extensively pre-fabricated model can be built in a very short time.
However, the remaining steps are important and have to be carried out with
care. Doing this work properly determines whether the model will have the
prescribed rigidity and flight characteristics; so please work slowly and
precisely!

Important safety notes

You have acquired a kit that can be assembled into a fully working RC model when
fitted out with suitable accessories. However, GRAUPNER has no control over
whether you observe the instructions for the installation and operation of the model or
for the use and maintenance of the associated components. For this reason
GRAUPNER assumes no liability for loss, damage, or costs, which are incurred due
to the incorrect use of our products or due to improper 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 GRAUPNER to pay compensation for any
reason whatsoever (including personal injury, death, damage to buildings, damage
due to loss of business or turnover, interruption of business, or other direct or indirect
consequent damage) stemming from the operation of the model is excluded.
The total liability in all cases and under all circumstances is limited to the amount of
money that you actually paid for this model.

This model is started up and operated at the sole and exclusive risk of the
operator. To avoid injuring people and damaging property, it is essential to be
careful and thoughtful when operating your model.

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. Therefore, you should purchase special RC model liability
insurance. Your local model shop will be glad to advise you.
These safety notes must be kept in a safe place, and, if you ever sell the model, must
be passed on to the buyer.

• If you intend to use dry cells as a power supply, please note that they must never
be recharged. Only rechargeable batteries can be re-charged.

• The batteries must be charged, and the range of the radio control system must
have been checked. In particular, the transmitter and receiver batteries must be
charged before each take-off.

• Ensure that the channel you intend to use is not already in use. Never fly the
model if you are not certain that your channel is free.

• Observe the instructions and information regarding your radio control system and
accessories.

• 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 before transporting and storing the model.

• Do not subject the model to intense humidity, heat, cold, or to dirt.

• Protect the model and RC equipment against damage during transport.

Pre-flight check

Check for correct functioning and range before every flight. To do so, screw in the
transmitter aerial and extend it fully. Then switch on the transmitter, followed by the
receiver. At an appropriate distance, make sure that all the control surfaces are
working properly and deflecting in the correct direction.
Repeat the check with the motor running, while someone holds the model securely
for you.
The first time you control a model aircraft, it is best to ask an experienced person to
help you with the pre-flight check and during the first few flights.

Care and maintenance

• Clean the model carefully after every flight. Also remove any dirt from the
propeller. Clean the model and the 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, all the moving parts
must be cleaned and re-lubricated.
