the rudder are noticeably slower. Replace damaged
batteries in a timely manner.
Always follow the manufacturers charging instructions.
Do not charge the batteries without monitoring them.
Never attempt to charge dry batteries. An acute
explosion hazard exists.
All batteries must be charged before each use. To
prevent short-circuits, first plug the banana plugs of the
charging cable into the charger (make sure the poles
are correct). Then plug in the charging cable plugs into
the sockets of the transmitter and receiver battery.
If you are not going to use your model for a while,
disconnect all power sources.
Never use rechargeable or replaceable batteries with
damaged, defective or different cell types; that is, a
mixture of old and new cells, or cells by a different
manufacturer.
Capacity and operating time
The following applies to all power sources: The capacity
decreases with each charge. At low temperatures,
the internal resistance increases while the capacity
decreases further. As a result, the battery's ability to
discharge and retain power is reduced.
Frequently charging and/or using battery care programs
can also gradually reduce the capacity. Nevertheless,
check the capacity of power sources at least every
six months, and replace them if their performance is
significantly low.
Only use original Graupner rechargeable batteries!
Suppressing interference in electric motors
All conventional electric motors generate
sparks between the collector and
brushes which more or less interfere with the
operation of the remote control system depending on
the type of motor.
Interference-suppressed electric motors are therefore
required for the system to work well. Particularly when
the models have an electric drive, the interference
for each motor must be carefully suppressed. Noise

Safety instructions
filters largely suppress such interference and must be
installed.
Follow the related instructions in the motor's operation
and installation instructions.
Additional details on noise filters can be found in the
main Graupner FS catalogue or on the Internet at www.
graupner.de.
Servo noise filters for extension cables
Order No. 1040
The servo noise filter is required when using longer-
than-usual servo cables. The filter is connected directly
to the receiver output. In critical cases, a second filter
can be placed on the servo.
Electronic speed controllers
The performance of the electric motor determines which
electronic speed controller is used.
To keep the speed controller from overloading or
becoming damaged, the current carrying capacity of
the speed controller should be at least 150 % that of the
maximum stall current of the motor.
Exercise caution with tuning motors, because they only
have a few windings and take several times their rated
current in a stall which can destroy the speed controller.
Electrical ignitions
Ignition systems of gas motors also generate inter-
ference that may impair the correct function of remote
controls.
The power supply for electrical ignitions should always
be from a separate source.
Only use interference-suppressed spark plugs and
spark plug connectors and shielded ignition cables.
The receiver should be at a sufficient distance from the
ignition system.
Static energy
WARNING:
Magnetic shock waves generated by
lightning can cause remote control
systems to malfunction even if the
lightning is miles away. If a thunderstorm is
approaching, land your model. Static discharge via
the antenna can also be life-threatening.
Note:
•
To satisfy the high-frequency transmission
requirements of the FCC for mobile trans-
mitters, a distance of 20 cm or more must
be maintained between the transmitter antenna and
people. Operation at a closer distance is therefore
not recommended.
•
Make sure that no other transmitter is closer than
20 cm to prevent electrical malfunctions and impair-
ment of emissions.
•
To operate the remote control system, the coun-
try setting must be correct for the transmitter. This
is required to satisfy the various national guidelines
(FCC, ETSI, CE, etc.). Follow the respective instruc-
tions for the transmitter and receiver.
•
Before each flight, perform at least one complete
range and function test, and run through an entire
flight simulation to determine if there are any prob-
lems with the system or the programming of the
model. Follow the instructions on page 77.
•
Never program the transmitter or receiver while us-
ing the model.
Care
Never clean the housing, antenna, etc. with
cleansers, gas, water, etc. Only use a dry, soft
P
cloth.
Components and accessories
NOTE:
As the manufacturer, Graupner|SJ GmbH
recommends only using components and
accessories that have been tested and
accepted by Firma Graupner|SJ GmbH for suitability,
functioning and safety. If this is done, Graupner|SJ
