In its default state and after a RESET the FAIL-SAFE function is
switched OFF, and is only activated when you select the FAIL-
SAFE settings for the first time. FAIL-SAFE is set using the SET
button on the receiver, or - in the case of certain transmitters -
“by radio”.
If you wish to disable FAIL-SAFE again, the receiver must be
reset to the default state (RESET
Î
8.5
). After a RESET you
must repeat the binding procedure (
Î
8.2.1
)!
!
Note: always activate FAIL-SAFE!
For safety reasons we recommend that you always activate
FAIL-SAFE, and ensure that the selected FAIL-SAFE settings
will cause the model to take up as safe an attitude as possible
(e.g. motor idle / electric motor OFF, control surfaces neutral,
landing flaps deployed, tow-release open, …).
Selecting the FAIL-SAFE settings:
Use your transmitter to move all the servos (and the speed
controller) to the desired position. Hold the SET button pressed
in briefly (0.5 to 1 second). This stores the FAIL-SAFE positions
for all servo channels; the LED flashes to confirm this (LED code 5
Î
8.1
).
Testing the FAIL-SAFE positions:
Move the sticks to positions other than the FAIL-SAFE settings,
and then switch the transmitter OFF: the servos should go into
HOLD mode briefly (0.75 seconds), and then move to the FAIL-
SAFE positions which you previously selected.
The FAIL-SAFE positions must always be checked and updated
when necessary, e.g. when you install the receiver in a new
model.
!
Checking the FAIL-SAFE function:
Never operate the receiver with the transmitter switched off for
longer than it takes to check the FAIL-SAFE function. Caution: if
the FAIL-SAFE position is incorrect, the motor could burst into
life - injury hazard!
After sixteen seconds in FAIL-SAFE mode the receiver no lon-
ger sends signals to the servos. Analogue servos and some
digital servos (see instructions) then become “soft”, to avoid
them being stalled. Modern speed controllers switch themselves
off. However, some digital servos remain “hard” and maintain
their last position.
8.5 RESET to default settings
The receiver settings can be reset to the factory default values if
you wish. If you do this, please note that all your settings (e.g.
binding information, FAIL-SAFE settings) will be lost.
Hold the SET button pressed in for at least ten seconds (as a
guide, the LED goes out when you press the button, comes on
again after two seconds, then off again after ten seconds).
When the RESET is complete, the receiver LED flashes to con-
firm the action (LED code 5
Î
8.1
), and the receiver switches to
binding mode.
!
Note:
a RESET is not possible if the receiver is in binding
mode (LED flashing at high rate).

Protect your receiver from vibration, especially in models
powered by an internal-combustion engine (e.g. pack it
loosely in foam).
x
Locate the receiver at least 150 mm away from electric mo-
tors, petrol engine ignition systems and any other electronic
components such as speed controllers for electric motors and
drive batteries. Do not route the aerial close to these com-
ponents.
x
Install the receiver in the model in such a way that the aerial
is as far away as possible from any conductive material.
x
If the fuselage is made of conductive material (e.g. carbon
fibre), the aerial must be installed in such a way that it is
located outside the model.
x
Do not deploy the aerial inside or resting against model
components which are skinned or reinforced with conductive
material (metal foil, carbon fibre, metallic paints, ...), as they
can have a shielding effect.
x
Do not shorten, lengthen or repair the aerial yourself.
x
Do not deploy the aerial parallel to servo leads, high-current
cables or electrically conductive components (e.g. pushrods).
x
High-current cables, e.g. those attached to the speed con-
troller, motor and flight battery, should be kept as short as
possible.
x
Reception quality can be optimised by fitting a special ferrite
ring (
# 8 5146
) in the speed controller cable. It is also
advisable to fit effective suppressors to conventional (brushed)
electric motors (not brushless types) (e.g. use the suppressor
set
# 8 5020
).

Regular range checks are very important - even when using a
2.4 GHz system - in order to ensure reliable operation of the
radio control system, and to enable you to detect sources of
interference in good time. This applies in particular:
x
Before the use of new or changed components, or existing
components in a new or modified arrangement.
x
Before re-using radio control system components which were
previously involved in a crash or a hard landing.
x
If you have encountered problems on a previous flight.
Important:
x
Always ask a second person to help you with your range
check, so that one of you can secure and observe the model.
x
If possible, carry out the range check when no other trans-
mitters are operating.
Carrying out the range check:
1. Select “Range check” mode on your transmitter (see the
operating instructions supplied with your M-LINK transmitter
or M-LINK RF module).
There must be line-of-sight contact between the transmitter
and the receiver aerial (i.e. the model) during the range
check.
Keep the transmitter and the model about one metre above
ground during the range check.
2. The range of the
RX-6 light M-LINK
receiver must be at least
forty metres with the transmitter set to low power. You have
reached the range limit when the servos start to move jerkily.
If your transmitter features an automatic servo test facility, we
recommend that you activate it for one control function (e.g.
rudder). This sets up a steady movement of the servo, and
enables you to detect the limit of range clearly.
Important:
Carry out the first range check with the motor switched off. Turn
the model in all directions and attitudes, and adjust the position
of the receiver and / or the aerial if necessary.
For the second range check, run the motor at varying speeds
and check that the effective range is not significantly reduced. If
there is a marked reduction, locate and eliminate the cause of
the interference (caused by the motor, the arrangement of the
receiving system and power supply, vibration, etc.).
