Please be sure to read through the safety notes in the Appendix to these operating instructions. If you ever dispose of the model, it is important to pass on the complete operating
instructions to the new owner.
Introduction
The ELEKTRO-ROOKIE S is a radio-controlled model aircraft with an excellent performance, designed specifically for the newcomer to the hobby. The aircraft can be
stored and transported safely and conveniently in the packaging carton.
Please start by reading right through these operating instructions - before you at-
tempt to operate the model - and make yourself familiar with the method of
operating your HoTT transmitter. Keep the manual for your HoTT COMPUTER
SYSTEM to hand when preparing the model.

Assembling the model
The model can very quickly be prepared for the air, but it is important to read and
observe the following notes, as this will avoid problems, especially on the first flight.
Note: To open the cockpit canopy, hold the rear portion by the sides and pull it
upward. This procedure may require a relatively great amount of force. However, the
holding power of the cockpit closure will lessen after a few opening attempts.
Connect the elevator horn as shown in the pictures, then fix the tailplane to the top of
the fin using the M4 x 25 mm countersunk screw (shown already fitted in the photo).

This requires the correct size of cross-point screwdriver, which is not included in the
pack.
The wing panels are assembled and fitted as shown in the illustration above: first join
the wings using the CFRP spar, then push the wings together. Please note that
pushing them together may require a relatively great amount of force. Tip: Putting the
wing halves together is easier if you first squeeze the two tabs of the left wing
together somewhat.
Note: the underside of the wings features recesses for aileron servos. The recesses
have no adverse effect on the model’s flying characteristics, but you can cover them
with the self-adhesive decals, Id. No. 0062349, if you wish; these are included in the
pack.
The COMPACT motor set
The high-quality COMPACT motor set is supplied already installed in the fuselage.
The matching speed controller is set up accurately at the factory to suit the
ELEKTRO-ROOKIE S, eliminating the need for programming. Please note that the
operating instructions for the BRUSHLESS CONTROL 18 speed controller are supplied separately in the pack.
Binding the GR-12 receiver in the model to your HoTT transmitter
The “BINDING” procedure varies according to the HoTT COMPUTER SYSTEM you
are using; please observe the following notes, and the section entitled “Binding the
receiver” in the manual supplied with your radio control system.
1. Give the LiPo flight battery and the transmitter battery a full charge.
2. Locate the right-hand stick on your transmitter, and move it back towards you to
the “motor stop” position.
3. Now connect the BEC plug and socket between the speed controller and the LiPo
battery.
4. Initiate the “BINDING” procedure, and then carry out a full check of the working
systems. The servo leads should be connected to the receiver in the following
sequence: socket 1: speed controller; socket 2: rudder servo; socket 3: elevator
servo. This means that the throttle (motor control) and direction (rudder control)
are both assigned to the right-hand stick on the transmitter, and the elevator to
the left-hand stick. Pulling the elevator stick back towards you causes the elevator
to deflect up; moving it away from you causes it to deflect down.
5. If necessary, use your transmitter’s “Servo settings” menu to correct the direction
of rotation of the servos, and set the control surfaces exactly to centre (neutral

position). This is very important, otherwise the model will not fly straight, and will
constantly tend to climb or dive.
6. Now it is time to check the motor function by cautiously moving the right-hand
stick forward (away from you). It is always better to test the motor outdoors, and it
is very useful to have a friend to hold the model securely while you operate the
transmitter.
This photo shows the HoTT GR-12 receiver connected to the other components, and
the completed BEC connection between the speed controller and the LiPo battery.
Control surface travels
We recommend the following maximum travels, in each case measured at the trailing
edge of the control surface: rudder 20 mm to either side of neutral, elevator 8 mm up
and down. The correct travels can be set at the transmitter; please refer to your HoTT
COMPUTER SYSTEM manual for information on this process.
Balancing
Assemble the model completely, ready to fly. The Centre of Gravity range is 70 to 80
mm aft of the wing root leading edge; this can be achieved by adjusting the position
of the LiPo flight battery. Support the model at the stated CG position with two fingers
under the wing roots, and allow it to hang freely: the fuselage will remain level when
the model is balanced correctly. Note: The model comes standard with a trim weight
on the underside of the battery compartment. Make sure this trim weight always
remains in the model.
Flying
Wait for a day with little or no breeze for the initial test-flight. The ideal flying site is a
flat grassy field with a gentle slope facing into wind. Never launch the model between
buildings or trees, as the air will be turbulent, making the aeroplane difficult to control.
If you are a complete beginner to flying model aircraft, it is extremely helpful if you
can find an experienced modeller to check the model and help during the first flights.
Switch the motor on and give the model a hand-launch exactly into any breeze;
trotting forward for a few steps gains the necessary momentum. The fuselage nose
should be inclined up slightly (approximately 15°) for launching.
You will undoubtedly need to trim the model after the first launch; fine-tuning can be
carried out by adjusting the trim buttons situated below and adjacent to the transmitter sticks. Always land the model directly into wind, with the motor switched off.
Just before touch-down, apply slight up-elevator to flare out and slow the machine

Safety Notes
Before you fly the model for the first time it is essential (and a legal requirement) to take out an
insurance policy designed to cover modelling risks.
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. You alone are responsible for the safe
operation of your radio-controlled model aeroplane. Young people should only be permitted to
build and fly this model under the instruction and supervision of an adult who is aware of the
hazards involved in flying an RC model aircraft.
In legal terms our models are classed as aircraft, and as such are subject to statutory
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.

It is important to use only those parts included in the kit, together with other genuine Graupner
accessories and replacement parts as recommended expressly by us. Even if you change a
single component, you can no longer be sure that the whole system will work reliably, and
such changes also invalidate your guarantee.
Avoid short circuits and reverse polarity at all times.
The high energy density of rechargeable batteries involves a permanent risk of fire and even
explosion.
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. Nobody would climb into a
full-size sailplane and try to fly it without first completing a course of training. Model flying is
just such a skill, and has to be learned in exactly the same way.
However, as manufacturers we have no means of influencing the way you build and operate
your RC model aircraft, and for this reason we can do no more than point out the hazards
expressly. We accept no further liability.
If you need help, please enlist the aid of an experienced modeller, join a model club or enrol at
a model flying training school. Model shops and the specialist model press are also good
sources of information. The best course is always to join a club and fly at the approved model
flying site.
The operator of the model must be in full possession of his or her bodily and mental faculties.
As with car driving, flying a model aircraft under the influence of alcohol or drugs is highly
dangerous and not permissible under any circumstances.
Make sure that all passers-by and onlookers are aware of the hazards involved in the operation
of your model. Remind spectators to keep a safe distance from the model.
Always maintain a safe distance between your model and other people or objects. Never fly low
over people or directly towards them.
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, the strength of glued joints and other unwanted effects.
All model flyers should behave in a way which minimises the danger to people and property.
Never act in any manner which will disturb other pilots, or have an adverse effect on safe,
orderly flying at the site.
Don’t operate your model in the vicinity of overhead power cables, industrial sites, residential
areas, public roads, school playgrounds, public parks or sports fields etc.
Pre-flight checks
Check that the radio control system works correctly before every flight: switch on the
transmitter and the receiving system, and check that all the control surfaces are at neutral,
work smoothly and immediately, and deflect in the correct “sense” in relation to the stick
movements.
If you are a beginner to this type of model flying, we recommend that you enlist an experienced
model pilot to help you check and test-fly the model.
Don’t ignore our warnings They refer to hazardous materials and processes which, if ignored,
can result in fatal injury or serious damage to property.
Propellers powered by a motor constitute a permanent hazard and represent 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 cut your finger badly.
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. In unfavourable circumstances this could result in serious injury. Ensure that the revolving propeller never comes into contact with any object.

Make sure that it is impossible for any object to stall or block the propeller.
Every time you intend to operate your model, check carefully that it and everything attached to
it (e.g. propeller, tailplane etc.) is in good condition and undamaged. If you find a fault, do not
fly the model until you have corrected it.
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.
Do not switch the electric motor on unless you have checked that there is nothing in the
rotational plane of the propeller. Never attempt to stop the propeller when it is spinning.
Electric motors with propellers fitted must only be run when firmly mounted.
If you are to fly your model safely and avoid problems, it is essential that you are aware of its
position and attitude throughout each flight - so don’t let it fly too far away. If you detect a control problem or interference during a flight, immediately land the model to prevent a potential
accident. Model aeroplanes must always give way to full-size aircraft. Take-off and landing
strips should be kept free of people and other obstacles.
Your HoTT COMPUTER SYSTEM can only work reliably if the batteries are kept fully charged.
Never use hot, faulty or damaged batteries. Observe the instructions provided by the battery
manufacturer 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. Provided that you take reasonable care, model flying is a highly
creative, instructive, enjoyable and relaxing pastime.
