Assembly instructions
Please read these building instructions completely before you start building, so that
you have a clear idea of the sequence required. Before each stage, identify all the
parts, tools and adhesives you will need, and have them ready. When working,
always lay the parts on a clean, smooth surface, or a layer of foam material. Unless
the instructions specifically state otherwise, use fast-setting glue with activator as
adhesive. The best method is to apply glue to one face, then spray activator on the

opposite face. Make sure that no residual adhesive gets on your hands or on the
surface of the model. Immediately wipe of excess adhesive with wood pulp paper.
Caution: Cyano-acrylates must not come into contact with any part of your
body or the eyes; for this reason, we recommend that you wear protective
goggles when using this material. Store the adhesive out of the reach of
children. For safety reasons, use only the adhesive mentioned above. Please
observe the operating instructions and safety notices for the respective
accessories.
The wing
First apply adhesive (UHU ALL PURPOSE ADHESIVE Power) to secure the already
inserted aileron and landing flap hinges.
Then push up the ailerons and flaps until there is a gap of about 1 mm. After waiting
for them to dry, check whether the rudders are secure.
Unscrew the servo cover from the wing and fit in the servo. Cut off the excess part of
the levers and drill the desired hole for the servo lever to Ø 1.8 mm. Put the servo
into the neutral position, attach the servo level vertically, and screw it tight. Use
cyano-acrylate to glue the servo to the respective attachment tab.
Insert a string to pull the servo lead carefully into the wing. Attach a 100 mm
extension cable to the aileron servos. Screw on the servo cover and make the aileron
and landing flap connection. Connect the pushrods and glue in the horns of the
ailerons.

The figure shows the completed aileron connection. Note that the length of the servo
levers should be a minimum of 14 mm to keep the clevis
from colliding with the wing.
The figure shows the completed landing flap connection. Note that the length of the
servo levers should be a minimum of 12 mm to keep the clevis
from colliding with the wing.
Note: Arrange the spreading landing gear so that the flap deflection is about 12 mm
with the servo in neutral position, as shown here. Set the full deflection to about 25
mm. It is best to operate the flaps on the transmitter with a 3-stage switch. The
asymmetrical servo arrangement makes it possible later to control both servos
without a mixer with a connector cable Order No. 3936.32 at one of the transmitter
outputs.
The figure shows the servo lead exiting at the wing root. Later, use the CRP tube Ø
5x125 mm to push the halves of the wing onto the fuselage.

Fuselage with tail group and cockpit canopy
First place the motor spindle, motor mount, and locking ring onto the motor; these
parts are included as accessories in the package for Order No. 7738.
The figure shows the individual parts for the motor spindle and motor mount; tighten
all screws.
The figure shows the motor with attached motor mount and motor spindle. Separate
the motor leads and remove about 5 mm of insulation. Apply solder to the ends of all
leads and then solder on the G 3.5 connectors (included with Order No. 7738);
insulate the connector shaft with the heat-shrink sleeves (included with Order No.
7738). Use a hair dryer to shrink the heat-shrink sleeve. Then do a test run of the
motor. Viewed in flight direction, the motor should rotate to the right; if this is not the
case, switch any two of the leads and re-insert.

First press the pronged nuts from behind into the motor bulkhead and secure with
glue. Using the 4 M 3x10 mm screws and the washers and locking rings shown,
screw the motor in tight. Position the motor so that the feed cables run under the right
side of the fuselage toward the back.
Pull the motor bulkhead all the way forward, glue it, and insert and glue the 8x8
chamfer strips. Also completely glue the motor bulkhead into the corners from the
front. Then do a test run of the motor. Viewed in flight direction, the motor should
rotate to the right; if this is not the case, switch any two of the leads and re-insert.
Thinly mark the mid-lines of the attachment tabs for the motor bonnet on the fuselage
so that they can be erased later. Slide on the spinner cap and motor bonnet. Align
the motor bonnet so that the spinner cap is exactly centred and is about 5 mm in front

of the forward edge of the motor bonnet. Hold the motor bonnet in place with tape,
and drill the Ø 1 mm attachment holes. Screw the motor bonnet on tight with four Ø
2.2x6 mm metal screws.
Place the GRP propeller spacer onto the propeller, enlarge the cut-outs in the spinner
cap to fit the propeller, and separate the two short pins on the spinner back plate so
that the spinner cap fits and can be pushed on without any stress. When everything
fits, attach the spinner to the propeller. Tighten the propeller attachment nut.
Use UHU ALL PURPOSE ADHESIVE Power to glue in the rudder hinges of the
tailplane and vertical stabilisers in accordance with the method already described;
glue the aileron connectors in with fast-setting glue. Use a geometric protractor and
overhead marker to exactly mark the midline of the tailplane, then on all the areas to
be glued to the fuselage and on the vertical stabiliser, and also use the hot tip of a
soldering gun to cut through the covering sheet, and pull it off.
Slide the tailplane into the fuselage exactly centred and glue it. For the lowest rudder
hinge of the rudder, cut a slit in the fuselage; then push on the vertical stabiliser as
well. First try this procedure without any adhesive. Above all, make sure you do not
use activator for the gluing process.

ADHESIVE Power; hold in place with tape.
Undercarriage
Included standard in the package is a rigid undercarriage; the model can also be
equipped with a retractable undercarriage (Order No. 193.3; of which 2 are
required). No additional servo is needed for the electric retractable undercarriage.
When using the connecting cable (Order No. 3936.32), only one receiver output is
required.
Caution: If you want to install only the rigid undercarriage, do not remove the
covering sheet over the cutout for the retractable undercarriage on the underside of
the wings. (See following assembly step photo.)
The figure shows how the undercarriage struts are inserted into the mounting block.
The covering sheet for the mounting block has been separated.
Glue in the completely pressed in undercarriage struts; secure with an attachment
tab and two Ø 2.2x12 metal screws as shown. Push on the wheel with the protruding
wheel hub facing the strut; then secure it with 2 plywood spacers.

Deals
Cut out the individual decals and name placards and apply them as shown in the
illustrations on the kit box.
Installing the receiver and LiPo battery
The first step is to connect the servo leads to the receiver; we recommend the
following sequence: speed controller to socket 1, left aileron servo to socket 2
(extension cable 100 mm), elevator servo to socket 3, rudder servo to socket 4, right
aileron servo to socket 5 (extension cable 100 mm), left landing flap socket 6
(extension cable 100 mm). Right landing flap to socket 7 (extension cable 100 mm),
retractable undercarriage to socket 8 (connecting cable); now do a test of all
functions using the radio control transmitter. Caution: After closing the G3.5
connector, the motor can start; do not touch the propeller!

The figure shows the LiPo battery held in place by hook-and-loop cable ties, the
speed controller, and the GR-16 HoTT receiver. Push the servo power lines into the
receiver before using two M4 plastic screws
to mount the wing on the fuselage
Rudder deflections
The following rudder deflections are recommended, but can be changed as desired.
Ailerons 15 mm in each direction, elevators 15 mm in each direction, rudder 30 mm.
All measured at the inboard or bottom edge of the rudder. For airbrake deflections,
see the section on "The wing."
Balancing
Check the balance with the model in ready-to-fly condition, meaning with the LiPo
inserted. The centre of gravity is 55 mm from the leading edge of the wing. Adjust it
by moving the LiPo battery as needed. Check the centre of gravity by simply
supporting the model near the centre of gravity under the wing on two fingers. The
model should balance level at the point indicated.
Flying
Fly the model for the first time with rudders in the neutral position on a day with little
or no breeze. A smooth runway into the wind is ideal for a ground start. If no runway
is available,
the model can be started by means of a hand start into the wind. Use minimal aileron
and elevator corrections to keep the model in a straight climb. The fine trim is done
via the trim slider below or next to the joysticks. Always land the model flying directly
into wind, with the motor idling but not switched off. Just before touch-down reduce
air speed through careful use of up-elevator. Always land the model into the wind.
Here at GRAUPNER Modellbau, we hope you will have many enjoyable flights with
your new aircraft model, the

Safety notes
Valid third-party insurance must be obtained before you operate any model aircraft; this is now
a legal requirement.
Before you attempt to assemble and fly the model, it is essential to carefully read all the
assembly and operating instructions. You alone are responsible for the safe operation of your
RC model aircraft. Young persons should be permitted to build and operate this model only
under the instruction and supervision of an adult who is aware of the hazards involved in this
activity.
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 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. In addition, you must also observe postal regulations for the radio control system. You
will find more information on this subject in the operating instructions for your radio control
system.
Be sure to use only those parts included in the kit, together with other genuine Graupner
accessories and replacement parts as recommended expressly by us. If you change a
component of the propulsion system, you can no longer be sure that the system will work
reliably, and such changes also invalidate your guarantee.
Take care to avoid short-circuits and reversed polarity.
The high energy of the LiPo batteries involves a risk of fire and explosion.
A radio-controlled model aircraft can only work properly and fulfil your expectations if it is built
with the greatest of care and in accordance with the assembly instructions. To avoid injuring
people and damaging property, it is essential to be careful and thoughtful when operating your
model. Nobody would climb into a full-size glider and attempt to fly it without undergoing
training beforehand. Successful model flying also requires training and practice.
As manufacturers, however, we are not in a position to influence the way you build and operate
your RC model aircraft. We therefore hereby expressly point out the hazards and reject any
liability.
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. It is always best to join a club and fly at the approved model flying site.
Adhesives contain materials which may be hazardous to health under certain circumstances.
You should therefore read and observe the notes and warnings supplied by the manufacturers
of these materials.
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.
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.
Always keep a safe distance from people and objects when flying; never fly low over people’s
heads, and never fly directly toward them!
Models should only be flown in a temperature range of -5°to +35 °C. Extreme temperatures can
lead to changes in battery capacity and material characteristics as well as weakened glued
joints, et cetera.
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.

Never operate your model aircraft close to high-tension overhead cables, industrial sites,
residential areas, public roads, squares, school playgrounds, public parks or sports grounds et
cetera.
Pre-flight check
Check for correct functioning before every flight. To do so, switch on the transmitter, followed
by the receiving system. Extend the transmitter aerial, then check that all the model’s control
surfaces are at neutral, work properly, and deflect in the proper 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.
Do not ignore warnings! They refer to materials and situations, which, if ignored, can - in
extreme cases - result in fatal injury or permanent damage.
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
can easily cut your finger.
Always keep well clear of the rotational plane of the propeller! You never know when some part
or even the entire propeller may come loose and fly off at high speed, hitting you or anybody
else in the vicinity. This could result in serious personal injury. Make sure that no other object
can come into contact with the rotating propeller.
Make sure that no object is blocking the propeller.
Every time you intend to operate your model, check carefully to ensure that it and everything
attached to it (such as the propeller, RC components, et cetera) are securely attached and
undamaged. If you find a fault, do not fly the model until you have corrected it.
Always make sure that your transmitter frequency is vacant. Do not switch on the transmitter
until you have! 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.
Do not switch on the electric motor unless you are sure that there is nothing in the rotational
plane of the propeller. Do not try to stop the rotating propeller. Electric motors with the
propeller attached should only be run when firmly mounted.
You should always be aware of the model’s position and attitude throughout each flight, so
that you can execute control and avoidance manoeuvres. If you detect a control problem or
interference during a flight, immediately land the model for the sake of safety. Models must
always give way to full-size aircraft. Take-off and landing strips should be free of people and
other obstacles.
To ensure proper operation of your RC system, make sure that the batteries are kept fully
charged.
Never use batteries which are hot, faulty or damaged. At all times heed the instructions
provided by the battery manufacturer.
Before each flight check that all functions on the model aircraft are working correctly, and that
the radio control system is in good order and operating at full range.
Note that the motor control function on the transmitter must always be moved to the OFF
position as the first stage in preparing for a flight. To keep the electric motor from starting
unexpectedly, always switch the transmitter on first, and only then the receiving system.
Likewise, always switch the receiving system off first and only then the transmitter.
Check that the control surfaces follow the movement of the transmitter joysticks.

After each session, remove the battery from the model, discharge it, and store it in a safe
place, well out of the reach of children, at a temperature in the range about +5°C to +25°C.
These notes are intended only to make you aware of the many dangers and hazards that can
arise if you work carelessly or irresponsibly. If you take reasonable care, model flying is a
highly creative, instructive, and relaxing pastime.
