Do not connect a separate receiver battery to the receiver,
as the controller supplies current to the receiver and servos
via the BEC circuit. Always keep to the maximum servo
count limit in BEC mode (

necessary (

5. U SING THE UNIT FOR THE FIRST TIME
MULTIcont BL-20 SD / SD-L controllers are set up by default to
work with LiPo batteries, and the brake is OFF.
0. First use of MULTIcont BL-20 SD / SD-L controllers
0.1 Programmable radio
control system:
set servo travel for
throttle / motor to 100%
on both sides of neutral
0.2 Move transmitter throttle
stick (and its trim) to the
motor OFF position
0.3 Transmitter ON
0.4 Connect fully-charged
flight battery
⇒ Rising sequence of sounds
⇒ LiPo mode: number of beeps
indicates the detection of a
LiPo battery with X cells
(in NiXX mode the following
signals are emitted immediately)
⇒ Long beep
⇒ Controller ready for use
Caution!
Rising sequence of
sounds after two beeps
Rapid sequence of
beeps
⇒ Controller is in programming
mode, because throttle channel is
reversed!
⇒ Throttle channel not at Idle.
! Note:
Programmable parameters
If you wish to change one of the programmable parameters,
please refer to the Programming section ( 6.).
Start-up protection
MULTIcont BL-20 BEC speed controllers 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. P ROGRAMMING
MULTIcont BL-20 SD / SD-L speed controllers are ultra-simple to
program using just the transmitter throttle stick.
The status of programming using the throttle stick is indicated by
beeps, which also confirm any changes. The program works
through all altered parameters and options step-by-step. The
desired parameters (points 3. - 9.) are selected by moving the
throttle stick to the Idle position. Leaving the throttle stick at the
full-throttle position automatically takes you to the next
programming option.
Leaving programming mode:
1) Once you have adjusted a programming point, you can leave
programming mode by moving the throttle stick to the Idle
position within two seconds of hearing the confirmation sound.
The controller is then ready for use.
2) When you hear a double long beep [▬ ▬] (Point 10), move
the throttle stick to Idle within three seconds, otherwise the
software will work through programming options 3. to 10. again.
1.
Calibrate stick travel / throttle travel
1.1 Flight battery disconnected
Throttle stick to full-throttle
Transmitter ON
1.2 Connect fully-charged flight
battery
⇒ Rising sound sequence
⇒ In LiPo mode:
indicates number of
Li-Po cells detected
⇒ In NiXX mode the
following signal is emitted
im-mediately
⇒ Two short beeps [•_•]
After two seconds:
confirmation that maximum
throttle position was
detected correctly
1.3 Stick to motor OFF position
⇒ Long beep [▬]
(Confirmation after one
second that “minimum”
throttle was detected
correctly)
1.4 Power system ready for use
2.
Activate programming mode
2.1 Flight battery disconnected
Stick to full-throttle position
Transmitter ON
2.2 Connect fully-charged flight
battery
⇒ Rising sound sequence
⇒ In LiPo mode:
Indicates number of
LiPo cells detected
⇒ In NiXX mode the
following signal is emitted
im-mediately
⇒ Two short beeps [•_•]
⇒ Rising sound sequence:
controller is in programming
mode
