Operating instructions for MULTIcont
BL-20 SD / SD-L brushless speed controllers
⇒ Stick to Idle position
within three seconds
⇒ "Beep [•]" -> Stick to full-
throttle position -> Low
⇒ "Beep beep [•_•]" -> Stick
to full-throttle position ->
Medium
⇒ "Beep beep beep [•_•_•]"
-> Stick to full-throttle
position -> High
⇒ Confirmation signal
emitted
Low is the default setting, and can be
used with most motors. If you are not
satisfied with your motor's running
characteristics -> try the Medium or High
setting.
⇒ Leave stick at full-throttle
position.
⇒ Stick to Idle position
within two seconds of
hearing confirmation signal
8.2
⇒ Stick to Idle position
within three seconds
⇒ Confirmation signal
emitted
=> Controller ready for use!
⇒ Stick to Idle position
⇒ Confirm signal emitted
=> Controller ready for use!
7. BEC = B
ATTERY
MULTIcont BL controllers are equipped with a high-performance
BEC system: current is supplied to the receiver and servos from
the flight battery via the controller. A separate receiver battery is
not required.
Do not connect a separate receiver battery!
Please note that the BEC system of MULTIcont BL controllers
can only supply a limited current for the airborne receiving
system. The maximum current which the BEC circuit can deliver
varies according to the operating voltage (battery voltage). The
higher the voltage, the lower the maximum BEC current:
max. P = (U – U ) x I

U = 5.0 V

The actual current drawn by a servo varies according to its
performance, the frequency of commands and – in parti-cular –
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.
! Note: disabling the BEC system
The 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, or
•
the model is powered by a NiXX flight battery with more than
nine cells
Disabling the BEC system: locate the UNI connector attached to
the three-core lead. Use a pointed instrument to raise the plastic
lug of the red wire (+), and withdraw the red wire from the plastic
housing. Insulate the bare metal parts with a heat-shrink sleeve.

OW VOLTAGE CUT
FUNCTION
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).
! 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.
! Note: if you are using the latest generation of LiPo batteries,
the low voltage cut-off function will not work correctly due to the
