AFETY OTES
! Read the instructions before using the controller
! Avoid heat build-up
Provide unobstructed air circulation round the controller
! Do not connect the flight battery with reversed polarity
Connecting the battery leads with reversed polarity will in-
stantly wreck the controller
For this reason:
• red wire to the POSITIVE terminal (+)
• black wire to the NEGATIVE terminal (-)
! When soldering or working on the motor or controller
Always disconnect the battery (short-circuit / injury hazard)
! When testing and running the power system
Do not run the motor while holding it in your hand; always se-
cure the model firmly.

PECIAL EATURES
MULTIPLEX MULTIcont BL-25 FLEXX speed controllers include
interesting features:
•
Direction of rotation: forward, brake and reverse
•
Fixed signal values: no calibration required
•
On / Off switch
•
Safety start system prevents motor starting accidentally when
battery is connected
•
Motor cut-off if serious radio interference occurs, or trans-
mitter signal fails
•
Temperature guard: if the controller overheats, it reduces
power to the motor.
! Caution: The BL-25 FLEXX
cannot be programmed with the MULTImate or PC!

IRING
! Note: when fitting your preferred plug / socket system in
order to connect the MULTIcont BL-25 FLEXX speed
controller to your motor and / or battery, please observe the
following points:
Soldering requires some care, as the quality of the joints is cru-
cial 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 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, simp-
ly swap over two of the three wires leading to the motor.
Connecting the three-core lead (UNI connector system) to
the receiver
Connect the three-core receiver lead (attached to the speed con-
troller) 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
