AFETY OTES
! Read the instructions before using the unit for the first time
! Avoid heat build-up:
Provide unhindered air circulation ar o und the controller.
! Do not connect the flight battery with reversed polarity:
Connecting the battery leads in reverse instantly ruins the controller.
For this reason: • red wire to the POSITIVE terminal ( + ),
• black wire to the NEGATIVE terminal ( - ).
! When soldering or otherwise 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 holding it in your hand; secure the model well. Check that
there is nothing obstructing the propeller. Keep all loose objects well away from the
propeller, especially those which could be sucked into the propeller or blown away
(clothing, small items, paper etc.). Never stand in or in front of the rotational plane
of the propeller (injury hazard).

IRING THE CONT
! Note:
Soldering may be necessary to connect the controller. Soldering requires a certain level
of care, as the quality of the joints determines the reliability of the power system:
•
Use only a type of solder designed for electronic soldering work
•
Do not use acid-based soldering flux
•
Parts to be soldered must be heated sufficiently, but not excessively
•
If you are unsure, ask a modeller experienced in soldering for help

Connecting the battery plugs
One end of the controller features only two cables plus the receiver lead; the battery
plugs are soldered to the wires at this end. Cut the battery wires (attached to the
battery) to the required length. Strip the wire ends to suit the battery plugs. Use cable
stripping pliers for this, or a knife if you have no strippers. Take care not to cut too
deeply, or you could damage the conductors. Maintain correct polarity when soldering the
battery plugs to the wires.
Important: it is essential to ensure that correct polarity is maintained!!
Reversed polarity inevitably ruins the controller completely!
Connecting the motor to the controller
One end of the controller features three cables; the motor is connected to the wires at
this end. Cut down the controller cables to the minimum possible length - don't shorten
the wires attached to the motor! Strip the wire ends so that sound soldered joints can
be made to the three motor wires. All three soldered joints must be insulated to prevent
short-circuits, using heat-shrink sleeving or insulating tape. Once you have established the
correct direction of motor rotation, i.e. when soldering is finished, insulate the joints
permanently with heat-shrink sleeves.
Reversing the direction of motor rotation
If you find that the motor rotates in the wrong direction, simply swap over any two of
the three wires running to the motor - that's all you have to do to reverse the direction
of motor rotation!

SING THE POWER SYSTEM FOR THE FIRST TIME
1. Connect the controller's receiver cable (BEC) to the receiver.
- MULTIPLEX RC systems: channel 4 = throttle / motor
- HITEC RC Systems: channel 3 = throttle / motor
2. If you have a programmable RC system: set the servo travel for
throttle /motor to 100% on both sides of neutral.
3. Set the transmitter throttle stick ( a nd trim! ) to the desired idle setting / motor OFF
end- p oint.
4. Switch the transmitter on
5. Connect the flight battery to the speed controller
Caution: reversed polarity will instantly ruin the controller!
Receiver connections
Connect the receiver lead attached to the controller to the throttle channel socket on the
receiver.
If you are using a flight pack containing 10 cells or less do not connect a separate
receiver battery, as the MULTIcont supplies power to the receiver and servos via the
BEC system and its servo lead.
