Thank you for purchasing this Microprocessor based Electronic

Speed Control (ESC) R/C system.

THESE INSTRUCTIONS REFER SPECIFICALLY FOR USE WITH

THE RCS TX-3, TX-5 and TX-7 HANDPIECES.

THERE ARE SEPARATE INSTRUCTIONS FOR USE WITH ANY 2.4

GHz R/C WITH 4 OR MORE CHANNELS.

THOSE OTHER INSTRUCTIONS REFER SPECIFICALLY TO THE

SPEKTRUM DX5e 2.4 GHz R/C.

THEY ALSO APPLY TO THE DX4e, DX6i & PLANET T5. N.B.

YOU CANNOT MIX BRANDS OF R/C.

THE RCS #OMEGA-3v5 SYSTEM IS IN ONE PART WITH

SERVO LEADS WHICH PLUG INTO ANY DSM2 COMPATIBLE

RX.

OR; USE ANY BRAND OF R/C WITH THE ADDITION OF FOUR

SERVO LEADS CONNECTED TO THE 6 WAY SCREW
TERMINAL ON THE ESC AND PLUGGED INTO THE
APPROPRIATE CONNECTIONS ON THE RX.

INSTRUCTIONS.

THESE INSTRUCTIONS REFER TO OPERATING PROGRAMS Av1 & Bv1.

AN ESC WITH OPERATING PROGRAM AV1 CAN BE USED WITH ANY TYPE OF DSM2 TRANSMITTER.

#OMEGA-3v5s HAS BEEN CALIBRATED AT THE FACTORY. ONCE RX IS “BOUND” TO TX THE SYSTEM IS READY TO USE AS IS.

THERE ARE MANY FEATURES WITHIN THE SYSTEM WHICH CAN BE PROGRAMMED. YOU WILL NEED TO DOWNLOAD THE FULL

INSTRUCTION MANUAL FROM THE RCS WEBSITE. THE PUSHBUTTON ON THE ESC PCB IS ONLY USED FOR PROGRAMMING.

DO NOT PRESS THE ESC BUTTON DURING OPERATION.

DO NOT CONNECT TO MAINS POWER (110 – 240V AC).

THE #OMEGA-3v5s CAN BE USED WITH ANY FILTERED DC SUPPLY SUCH AS BATTERY POWER.

THEY HAVE CONSTANT BRIGHTNESS DIRECTIONAL LIGHTS & 2 SOUND TRIGGERS.

THE FOLLOWING MAXIMUM VOLTAGES MENTIONED ARE THE NOMINAL VOLTAGE & TAKE INTO ACCOUNT THAT FULLY

CHARGED BATTERIES CAN & DO EXCEED THE NOMINAL VOLTAGE.

USE 14v – 20v FOR THE #OMEGA-3v5s. A high voltage version is available.

We tested this system three times during manufacture. It was working normally when it left our factory.

If damage in transit has occurred, please return to place of purchase for attention.

THE ESC IS GUARANTEED FOR ONE YEAR.

The solid state motor driver output IC is guaranteed for life.

You will supply a locomotive or trail car, the 14 – 20 volt traction batteries (depending on ESC), a fuse,

ON-OFF switch and wires where necessary, to connect the ESC to the battery and motor(s).

Where soldering is necessary, we recommend a low wattage soldering iron and resin core solder.

TO AVOID CONFUSION WITH OTHER OPERATORS, WE SUGGEST YOU MARK THE TX TO

SHOW WHICH LOCO IT OPERATES.

CAUTION

DO NOT ATTEMPT TO ALTER THE TUNING OF THE RADIO EQUIPMENT.

DO NOT USE RADIO CONTROL EQUIPMENT IN THUNDERSTORMS.

CHILDREN UNDER 12: ADULT SUPERVISION RECOMMENDED DURING USE.

INSTALLING THE #OMEGA-3v5s ESC.

The #OMEGA-3v5s ESC uses any DSM2/DSMX 6 x Channel RX’s including our own “Auto Binding” DSM2-EM(AB)
Rx & SPEKTRUM or the ORANGE brand from Hobby King. Servo leads are supplied for connecting the ESC to the RX.
Always make sure the servo leads are connected to the correct sockets on the RX.

THESE INSTRUCTIONS REFER TO OUR OWN DSM2 TX HANDPIECES.

CONTROL KNOBS.

The TX-3, TX-5 & TX-7 handpieces all use a small knob for selecting direction change & a large knob for speed control.

USING EXTRA SERVOS.
The #OMEGA-3V5s ESC permits the operation of a regular servo using Ch # 5. Simply plug the servo leads the right
way around into the Ch # 5 servo header so marked in the RX. See the ESC diagram.

SOUND TRIGGER CONTROLS.
The TX-3 has one Ch # 5 pushbutton for triggering a sound system. Plug the Ch # 2 servo lead into the Ch 5 position on

the RX. Activates F2 on the trigger outputs. Or use as a mechanical servo action.

The TX-5 has two knobs for sound triggers although they can be awkward to use. Outputs are F1, F2, F3 & F4. The Ch
5 pushbutton is also available. See TX-3 above.

The TX-7 has four pushbuttons on the handpiece that are intended to trigger 4 x sound effects or control accessories.
They operate F1, F2, F3 & F4 on this ESC. The Ch 5 pushbutton is also available. See TX-3 above.

A pushbutton on the ESC pcb is used for initial speed calibration and making system program changes such as Start/Max
voltage, default direction start, system reset & sound trigger outputs from momentary to latch ON – OFF. If you need to
calibrate the system you must download the full instruction manual from the RCS website. See URL on page # 1.

LOCOMOTIVE SEPARATION.

2.4 GHz R/C systems are not separated with crystals. Every TX has a unique identifier code. They are all legal for air &
ground use. Most SPEKTRUM RX’s (and DSM2 clones) can be “BOUND” to the TX 20 handpieces.

“BINDING” must be done before the system can be used. See page # 4.

You can mount the #OMEGA-3v5s PCB with double stick tape or non conductive silicone. Do not allow metal objects
to touch the rear of the PCB. Damage to the PCB may result.

The

# ESC-LEADS

kit.

These connect any 2.4 GHz RX to the

# OMEGA-3v5 ESC.

Insert the

# ESC-LEADS

as follows.

1 = Throttle. 2 = Aileron.

3 = Elevator. 4 = Rudder.

Insert the 1 x 3 way servo cable into the

DSM2 RX #1 Throttle servo output.

Single leads go into A (2), E (3) & R (4).

PLACING RX ANTENNA.
It does not matter where you place the RX and antenna(s). We have at least 150’ + range with the system in plastic
locos. There is NO “glitching” or “Rusty Bolt Effect”. 2.4 GHz RX’s have been successfully used for some years with the
RX & antenna inside a dummy water tank of a live steam loco and inside expensive brass electric locos.
Turn the 2.4 GHz TX OFF to save the batteries & the loco will “Cruise” along until the TX is turned ON again & manual
control resumed.

INSTALLATION OPTIONS.

There are a number of different ways to wire up a loco. See wiring diagram pages. The two most popular are:

1. The simplest method is to connect the motor outputs (M & M) to what were the now isolated track pick ups. The loco
will behave exactly as it would if it were running on track power. That is, the lights for example will rise and fall with motor
voltage or come on before the loco starts moving. No other changes are necessary. This is ideal for trail car set ups.

2. Rewire the lights so that the loco will have constant brightness auto reversing head and tail lights. This can get
complicated and is not advised unless the installer has some experience. See below.

POWER SOURCES.

The #OMEGA-3v5s ESC can only be used with battery power as it comes. Ensure the battery pack is fully charged
before use. Contact RCS for information on how to use the ESC with a constant track voltage.

N.B. The absolute minimum voltage is 12 volts. If you use any less voltage the system will still respond, as in
the LED’s will light and respond to direction change, but the motor drive output will not work.

Connect the traction battery, which MUST BE FUSED, as per the wiring diagram.

RCS R/C offers a variety of installation kits for on board use such as the # BIK-U3/6 which has screw terminals to simplify

installations. For trail car installations we also have the # BIK-TC2/3 and # BIK-TC5.

MOTOR CONNECTION.
With #OMEGA-3v5s connect the motor(s) as per the wiring diagrams to M & M. The M + motor output is positive (+) in
a forward direction. Our extensive testing has shown the system doesn’t need any motor “Noise” suppression.

SHORT CIRCUIT & OVERLOAD PROTECTION.

RCS ESC’s are self protecting. Although there is output overload and short circuit protection built into them, it is

essential the battery supply be fused for overall system protection. See the wiring diagram pages.

LOCOMOTIVE LIGHTING.

RCS ESC’s have transistor controlled directional lighting. Please note: Maximum current is 100 ma per terminal.

N.B. Any greater load than 200 ma will kill the switching transistors which are not covered by warranty.

2 – 3 LED’s per output will be just fine but, please do not try and run multiple incandescent bulbs with the outputs. .
The #OMEGA-3v5s requires connecting the lights to the 4 x screw terminals as per the ESC diagram.

+ = Common + voltage (input less .7 volt). - = Common – (ground), F = Front Light, R = Rear Light.

IT IS MOST IMPORTANT THAT THE LIGHT BULBS BE COMPLETELY ISOLATED FROM ANY OTHER WIRING.

Instead of rewiring some locos, sometimes it is much simpler to control the regular loco wiring by simply reversing the
traction battery voltage. You can use the # RELAY-1v2 to do this as it can save a lot of wiring in many locos. It is
especially useful in USA Trains® locos to control incandescent bulbs or LED’s up to 1 amp & smoke features.
Please note: If the # RELAY-1v2 is used, the lights will flash alternately, not together as with transistor outputs.
When the system is in neutral only one set of lights will be lit.

The instructions assume the operator has used the available front & rear transistor lighting outputs or # RELAY-1v2.
If you do not have any lighting outputs connected you MUST be able to observe the LED’s on the ESC.

DEFAULT START UP DIRECTION.

In case the system is wired back to front the default direction will also need to be reset. See page # 6 section

3.4. You may also need to reverse the F & R lighting wires.
THE PICS BELOW SHOW:

1. Where the pushbutton is located on t

he #OMEGA-3v5s

PCB for speed calibration and programming.

2. Where the controlled lighting outputs (+ - F & R) and function triggers (1, 2, 3 & 4) are connected.
