Introduction: the XS-6 FM RACE radio control system
Charging batteries
All rechargeable packs must be charged before each
session. Keep to the battery manufacturer’s
recommendations for charging, and do not exceed the
stated charge times.
Never
leave batteries on charge unsupervised.
Never
attempt to recharge dry cells, as they may explode.
Charging the transmitter batteries
The transmitter battery compartment can be fitted with
individual rechargeable cells.
Be sure to use cells of the Mignon / AA / R6 size.
If the transmitter is fitted with rechargeable cells, they
can be recharged via the charge socket mounted on the
side of the transmitter. Note that the transmitter must be
set to “
OFF
” for the full period of the charge process.
The transmitter charge socket is fitted with a reverse-
flow guard circuit which prevents damage to the
transmitter electronics if the banana plugs on the charge
lead are short-circuited or connected with reverse polarity.
The transmitter battery
cannot be charged
using an
automatic charger due to the presence of the protective
circuit.
Maximum transmitter charge current
To avoid damage to the transmitter the charge current
should
never
exceed
500 mA (0.5 A)
. Always keep to
the recommendations for charging and general handling
stated by the manufacturer of the battery and charger.
Capacity and operating times
This rule applies to all forms of electrical power source:
at low temperatures capacity is greatly reduced, i.e.
operating times are shorter in cold conditions.
Suppressing electric motors
In electric-powered models every motor must be
thoroughly suppressed. Some electric motors are fitted
with basic suppression measures as standard, but these
are generally not adequate for our purposes - they are
only designed to satisfy legal requirements. Please read
the notes and recommendations supplied by the model’s
manufacturer.
Refer to the main GRAUPNER FS catalogue for details
of suppressor filters.
Using electronic speed controllers
When selecting an electronic speed controller you should
take into account the type and size of the electric motor
and the nature of the radio-controlled model. To avoid
overloading and damaging the speed controller, its
continuous load capacity should be
at least
half of the
maximum motor stall current. This means: if the motor
draws 100 A when stalled, the speed controller should
be rated at 50 A continuous current.
Take particular care if you wish to use a “tuning” or “hot”
motor. These have a small number of turns on the
winding, which means that the stall current may be
several times higher than its nominal current. Stalling a
motor of this type would destroy the speed controller
immediately.
In model boats an even higher safety margin should be
invoked. If the propeller is stalled by floating weed or
other debris, the speed controller is subjected to the
motor’s full stall current.
Check the direction of running
Many speed controllers with a reverse stage have a lower
current capacity in reverse than in forward running.
For this reason it is essential to check that your speed
controller is in “forwards” mode when the car is actually
moving forward.
Liability exclusion / Compensation
As manufacturers, we at
GRAUPNER
are not in a
position to influence 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
incompetent or incorrect use and operation of our
products, 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 limited to
the invoice value of that quantity of
GRAUPNER
products
which was immediately and directly involved in the event
in which the damage was caused.
Be sure to keep to our safety recommendations!
