! Note: information regarding soldering
Soldering will be required in order to use certain variants of
the MULTIcont BL speed controllers. 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
• Do not use acid-based solder flux
• 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 heat-shrink sleeve on each wire, and
shrink the sleeve
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
( 6.4.).
Connecting the three-core lead (UNI connector sys-
tem) to the receiver
Connect the three-core receiver lead (attached to the
speed controller) to the receiver input socket used for
motor speed control:
- With MULTIPLEX RC systems: channel 4 = throttle /
motor
- With HiTEC RC systems: channel 3 = throttle / motor

Positive pin (+)
Signal ( )
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 (

SING THE UNIT FOR THE FIRST TIME
By default, MULTIcont BL speed controllers are set up for
use with 2S or 3S LiPo batteries; the brake is OFF.
1. Using the MULTIcont BL controller for the first time
1.1 Programmable RC
system
set servo travel for
throttle / motor to
100% in both
directions
1.2 Move transmitter
throttle stick (and trim,
if present) to the motor
OFF position
1.3 Transmitter ON
1.4 Connect a fully-
charged flight battery
joint.
In the motor OFF position you will hear a single beep at
intervals of around thirty seconds. This is a reminder that
your model is switched on.
! Note:
Programmable parameters
If you wish to use NiXX cells, to switch the brake on (e.g.
for a folding propeller) or to reverse the direction of motor
rotation, please refer to the Programming section (
Start-up protection
MULTIcont BL 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.
⇒ Rising sequence of beeps
⇒ In LiPo mode:
two or three beeps indicate
detection of a 2S or 3S LiPo
battery
⇒ Two rising beep sequences
⇒ Controller is ready for use
