ROGRAMMING
Programming MULTIcont BL controllers could hardly be
simpler. It is carried out using the transmitter throttle stick.
Audible beeps indicate the status of the programming and
confirm any changes you make. All three programmable
parameters are adjusted step by step in sequence. The
desired programming option is selected by moving the
throttle stick either to the full-throttle or the motor OFF
position. Moving the stick back to centre moves on to the
next programmable parameter.
The software used in MULTIcont BL speed controllers is
designed to make it virtually impossible to enter pro-
gramming mode accidentally. As a result it may appear to
take quite a while to move to programming mode, but we
consider this procedure sensible in order to protect you
from accidentally switching to programming mode while
you are preparing for flight, or even during a flight.
1. Activating programming mode
1.1 Disconnect flight battery
Stick to full-throttle
Transmitter ON
1.2 Connect fully-charged
flight battery
1.3 Stick to centre
1.4 Stick to full-throttle
1.5 Stick to centre
2. Select battery mode
(single beep; repeated continuously)
2.1 For automatic low-voltage
cut-off for LiPo batteries*
→ Stick to full-throttle
OR:
For NiXX batteries
→ Stick to motor OFF
2.2 Stick to centre
3. Select brake mode
(double beep; repeated continuously)
3.1 For brake ON
→ Stick to full-throttle
OR:
For brake OFF*
→ Stick to motor OFF
3.2 Stick to centre
4. Select direction of rotation
(triple beep; repeated continuously)
4.1 For standard direction of
rotation*

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
BEC BATT BEC
U = 5.0 V
BEC
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.
