Servo interference filters for extension cables
Order No. 1040
The servo interference filter is necessary when an
extended-length servo cable is used. This filter is attached
directly to the receiver output. In critical cases a second
filter can be attached to the servo.
Using electronic speed controllers
Choosing the right electronic speed controller largely
depends on the power of the motor used.
In order to prevent an overload or damage to the speed
controller, its current rating should be at least half of the
maximum locked-rotor current rating of the motor.
Special caution is necessary in the case of motors refer-
red to as 'tuning motors'. Due to the small number of coil
windings, such motors can draw a multiple of their rated
current in a locked-rotor condition, leading to irreparable
damage to the speed controller.
Electric ignition systems
Combustion engine ignition systems also produce interfe-
rence that can adversely affect remote control functioning.
Always supply power to an electric ignition system from a
separate, dedicated battery.
Use only interference-suppressed spark plugs, spark plug
connectors and shielded ignition cables.
Mount the receiver at an adequate distnce from ignition
system components.
Static charges
Warning:
Lightening results in magnetic shock waves that
interfere with the functioning of a remote control
system – even if the storm is miles away.
Therefore ...
... stop flying right away if a storm is approaching. Static
charges gathered via the antenna also represent a lethal
hazard.
Note
•
In order to fulfill FCC RF emission requirements for
mobile transmitters, a distance of at least 20 cm must
be maintained between the system antenna and any
persons while this system is being operated. Opera-
tion of this system at a smaller distance is therefore
not recommended.
•
To avoid disturbance caused by the electrical
properties and emission characteristics of other
transmitters, maintain a distance at least 20 cm from
other transmitters.
Safety notices
30 30
•
To operate the remote control system, the transmitter
unit requires the correct program setting for the given
country. This is necessary for compliance with various
regulations such as FCC, ETSI, CE etc. Follow the
specific instructions on this provided with the trans-
mitter and receiver.
•
Prior to every flight, perform a complete functional
test, range test and execute a complete simulated
flight in order to rule out any possibility of system
faults or problems with the model's programming.
•
Never program the transmitter or receiver while the
model is being operated.
Care and maintenance
Never clean the housing or other parts with cleaning
agents, gasoline, water or similar means. Use only a dry,
soft cloth.
Components and accessories
As manufacturer of this equipment, Graupner/SJ GmbH
recommends only components and accessories which
have been tested and approved by Graupner for suitabi-
lity, functioning and safety. Where this recommendation
is followed, Graupner/SJ retains responsibility for the
product.
Graupner/SJ cannot accept any liability for non-approved
parts or accessories supplied by other manufacturers and
cannot assess every individual third party product as to
suitability of use without safety risk.
Liability exclusion / damage compensation
Where remote control components are installed, ope-
rated, utilized or maintained, Graupner/SJ cannot monitor
compliance with the assembly or operating instructions
or the related conditions and methods used. Graupner/
SJ consequently accepts no liability whatsoever for loss,
damage or costs resulting from or in any way related to
incorrect usage or operation.
Unless otherwise prescribed by law, the obligation of
Graupner/SJ to provide damage compensation, regard-
less of legal grounds, is limited to the invoice value of the
quantity of goods supplied by Graupner/SJ that is directly
involved in the event resulting in damage. This does
not apply if Graupner is found to be subject to unlimited
liability on grounds of intent or gross negligence pursuant
to binding provisions of law.
