English
These operating instructions are an integral part of this
product. They contain important information and safety
notes, and should therefore be kept in a safe place at all
times. Be sure to pass them on to the new owner if you ever
dispose of the product.
1. SAFETY NOTES
Q Read the instructions before using the controller
Q Avoid heat build-up
Provide unobstructed air circulation round the controller
Q Do not connect the flight battery with reversed polarity
Connecting the battery leads with reversed polarity will
instantly wreck the controller
For this reason:
• red wire to the POSITIVE terminal (+)
• black wire to the NEGATIVE terminal (-)
Q When soldering or working on the motor or controller
Always disconnect the battery (short-circuit / injury hazard)
Q When testing and running the power system
Do not run the motor while holding it in your hand; always
secure the model firmly. Check that there is adequate space
for the propeller to rotate. Remove all objects from the area
around the propeller which could be sucked in or blown away
(clothing, paper etc.). Never stand in the rotational plane of
the propeller (injury hazard).

4. WIRING
Q Note: if you wish to use a different connector system for
connecting a ROXXY BL-Control S-BEC speed controller to
your motor and / or battery, please note the following information:
Soldering requires some care, as the quality of the joints is
crucial to the reliability of the power system:
Use electronic-grade solder for all soldered joints
Parts to be soldered must be hot enough (the solder must
flow), but must not be overheated (damage to components)
If you are unsure, ask a modeller with experience in soldering
to help you
Carefully insulate all solder joints and bare wires (e.g. using
heat-shrink sleeving)
Attaching the battery connectors
The battery connectors have to be attached to the two wires (red
= +, black = -). Keep the wires as short as possible. If necessary,
cut the battery leads to the required length. Fit a piece of heatshrink sleeve on each wire, and shrink the sleeve over the
soldered joint. Take great care to maintain correct polarity when
soldering the battery connectors to the leads. Reversed polarity
inevitably and invariably wrecks the controller.
Connecting the speed controller to the motor
The motor is connected to the three wires which exit one end of
the controller. Solder sockets to the wires which match the motor
connectors, and insulate each soldered joint with a separate
heat-shrink sleeve. Keep the leads as short as possible.
If you need to reverse the direction of rotation of the motor,
simply swap over two of the three wires leading to the motor;
alternatively change the direction by programming ( 6.3.).

the receiver

please refer to the Programming section ( 6.).
Start-up protection
The ROXXY BL-Control S-BEC speed controller are only armed
when the throttle stick is moved to the motor OFF position, and
when the audible “ready” indication has been emitted.
Always carry out a range check
Every time you wish to fly, carry out a range check with the RC
system switched on. Check in particular that radio range is not
diminished at full-throttle and half-throttle, and that no
interference occurs. Watch the servos in the model: if they jitter
or carry out random movements, this indicates an interference
problem which must be solved.
6. PROGRAMMING
Programming the ROXXY BL-Control S-BEC speed controller
could hardly be simpler; it is carried out using the transmitter
throttle stick or the MULTIPLEX MULTImate # 8 2094.
Beeps indicate the status of programming when using the
transmitter stick, and also confirm any changes. The procedure
runs through all variable parameters step by step. You select the
desired programming option by moving the throttle stick either to
the full-throttle or motor OFF position. Returning the stick to
centre takes you on to the next programmable parameter.

7. S-BEC = SWITCHING BEC
The ROXXY BL-Control S-BEC speed controller are equipped with a
high-performance regulator BEC system: the receiver and servos are
fed power from the flight battery via the regulator; no separate
receiver battery is required.
Never connect a separate receiver battery!
Please note that the ROXXY BL-Control S-BEC speed controller SBEC power supply can only deliver a limited current to the receiving
system in the model:
The actual current drawn by a servo varies according to its
performance, the frequency of commands and – in particular – the
freedom of movement of the control surface linkages (!). This means
that it is essential to measure the current drain of the servos in the
model before the first flight, and at regular intervals thereafter.
If you have no means of measuring the BEC current: carry out a test
run on the ground: operate the servos in a “normal” way (similar to
flying the model) until the low-voltage cut-off is triggered (i.e. battery
flat). At this point the speed controller should be no more than warm
to the touch, and the servos must work properly all the time, without
ever threatening to fail or move erratically.
Q Note: disabling the S-BEC system
The S-BEC system must be disabled, and a separate receiver
battery must be used instead, if:
the model carries more servos, or servos with a higher current
drain, than is permissible for the selected battery cell count ( 2.), or
problems are evident during the test-run
Disabling the S-BEC system: locate the UNI connector attached to
the three-core lead and remove the red wire (+). Insulate the bare
metal parts with a heat-shrink sleeve.
8. LOW-VOLTAGE CUT-OFF WITH RESET FUNCTION
7.2
8.2
9.1
Confirmation signal
emitted
Select model type
(nine-times beep, continuously repeated)
If the battery voltage falls to the low-voltage threshold, the controller
automatically cuts off power to the motor. This ensures that sufficient
energy is available for the BEC power supply to allow a safe landing
to be carried out. A steady decline in motor speed is a further
indication that the flight battery is almost discharged; you should
initiate the landing as soon as you become aware of this.
If the controller cuts the motor, it can be switched on again briefly if
required by momentarily moving the throttle stick to the motor OFF
position (Reset function).
Q Note: do not use the low-voltage reset function more than
once or twice
Repeated throttling back to re-arm the motor may dis-charge the
flight battery to the point where the receiver power supply falters and
fails. Note that LiPo flight batteries can be permanently damaged if
they are deep-discharged.
Seite 6/10
Notice d’utilisation ROXXY BL-Control 720/755 S-BEC
Q Note: If you are using the latest generation of LiPo batteries, the
low voltage cut-off function will not work correctly due to the cells’
constantly high voltage curve; in this case the speed controller is
unable to cut the motor in good time. In these circumstances you
should fly using a current sensor or a timer, to avoid discharging the
drive battery to a dangerous level.
9. FAULT-FINDING, FAULT CORRECTION
Instructions ROXXY BL-Control S-BEC, # 82 5760 (16-09-23/JES) • Errors and omissions excepted! • MULTIPLEX
The controller switches the motor off after a few seconds
The controller will switch the motor off immediately if the battery
voltage falls below the low-voltage threshold. This is designed to
prevent loss of control of the model due to low voltage at the
receiver. If the battery is fully charged and you apply full-throttle, a
motor cut indicates a serious voltage collapse in the flight battery.
Measure the current drain, or fit a battery with a higher current
delivery capacity (higher C-rate).
Serious interference or failure of the transmitter signal will also cause
the controller to cut the motor immediately. Throttle the motor back,
wait about one second, then re-arm the controller by opening the
throttle again; this will only work if proper reception has been
restored.
Everything is connected correctly, the S-BEC system is
working, the servos are operating, but the throttle function does
not work
You probably did not wait long enough in the motor OFF position
after connecting the flight battery; this means that the controller is not
armed. Move the stick back to the motor OFF position (trim also at
idle end-point) and wait one or two seconds. Check that the throttle
channel is set to full travel, i.e. at least 100%. If the two rising beep
sequences still do not sound, and the motor still does not start, you
need to reverse the direction of operation of the throttle channel at
the transmitter.
Nothing works: receiver, servos and ESC do not function at all
Check all plugs, sockets and solder joints for intermittent contact,
and check again for correct polarity (+/-). If the unit still does not
work, contact the dealer from whom you purchased the speed
controller.
