Capacity and operating times
This rule applies to all forms of electrical power sour-
ce: capacity is greatly reduced at low temperatures,
i. e. operating times are shorter in cold conditions.
Frequent charging of batteries, and use of battery
maintenance programs, can also result in a gradual
loss of battery capacity. For this reason you should al-
ways check the actual capacity of your packs at regu-
lar intervals - every six months at least.
Purchase only genuine GRAUPNER batteries!
Suppressing electric motors
All conventional electric motors produce sparks bet-
ween commutator and brushes, to a greater or lesser
extent depending on the motor type; the sparking ge-
nerates serious interference to the radio control sys-
tem.
In electric-powered models every motor must there-
fore be thoroughly suppressed. Suppressor fi lters ef-
fectively eliminate such interference, and should al-
ways be fi tted.
Please read the notes and recommendations sup-
plied by the motor’s manufacturer. Refer to the main
GRAUPNER FS catalogue for more information on
suppressor fi lters.
Servo suppressor fi lters for extension leads
Order No. 1040
Servo suppressor fi lters are required if you are obli-
ged to use long servo extension leads, as they elimi-
nate the danger of de-tuning the receiver. The fi lter is
connected directly to the receiver input. In very diffi -
cult cases a second fi lter can be used, positioned clo-
se to the servo.
Using electronic speed controllers
Electronic speed controllers must be chosen to suit
the size of electric motor which they will control.
There is always a danger of overloading and possibly
damaging the speed controller, but you can avoid this
by ensuring that the controller’s current-handling ca-
pacity is at least half the motor’s maximum stall cur-
rent.
Particular care is called for if you are using a “hot” (i. e.
upgrade) motor, as any low-turn motor (small number
of turns on the winding) may draw many times its no-
minal current when stalled, and the high current can
easily wreck the speed controller.
Electrical ignition systems
Ignition systems for internal combustion engines can
also produce interference which has an adverse ef-
fect on the operation of the radio control system.
Electrical ignition systems should always be powered
by a separate battery – not the receiver battery.
Be sure to use effectively suppressed spark plugs
and plug caps, and shielded ignition leads.
Keep the receiving system an adequate distance
away from the ignition system.
Static charges
The operation of a radio control system can be affec-
ted by magnetic shock waves which are generated by
lightning – even when the storm is several kilometres
away. For this reason …
… if you see a storm approaching, cease opera-
tions immediately! Static charges via the trans-
mitter aerial also constitute a lethal danger!
Caution
Radio control systems may only be operated on the
frequency bands and spot frequencies which are ap-
proved for that purpose in the country in which the
equipment is used. Information on this can be found
in the section entitled “Approved Operating Frequen-
cies” on page 206. It is prohibited by law to use radio
control systems on any other frequency, and such mis-
use will be punished by the relevant authorities.
Care and maintenance
Don’t use cleaning agents, petrol, water or other sol-
vents to clean this equipment. If the case, the whip
aerial etc. should become soiled, wipe clean with a
soft dry cloth.
Components and accessories
As manufacturer of this equipment, GRAUPNER
GmbH & Co. KG recommends that you only use com-
ponents and accessories which have been checked
by
GRAUPNER and are known to work properly and
reliably. If you observe this advice, GRAUPNER ac-
cepts product responsibility.
GRAUPNER does not accept liability if this equip-
ment is used in conjunction with components or
accessories made by other manufacturers which
have not been approved. We are not in a position
to assess whether every individual product made
by other companies can be used with safety.
Liability exclusion / Compensation
As manufacturers, we at GRAUPNER are not in a po-
sition to infl uence the way you install, operate and
maintain the radio control system components. For
this reason we are obliged to refute all liability for loss,
damage or costs which are incurred due to the in-
competent or incorrect use and operation of our pro-
ducts, or which are connected with such operation in
any way.
Unless otherwise prescribed by law, the obligation of
the
GRAUPNER company to pay compensation is li-
mited to the invoice value of that quantity of GRAUP-
NER products which was immediately and directly in-
volved in the event in which the damage occurred.
This does not apply if GRAUPNER is found to be sub-
ject to unlimited liability according to binding legal re-
gulation on account of deliberate or gross negligence.
