The Rooster 12T has the industry-standard receiver input connector on a
user-replaceable input harness &
works with all major radio brand’s new
receivers
. However, some very old receivers must have the wiring sequence
in the plastic 3-pin connector housing changed.
This is important, because
receiver & servo electronics may be damaged if the sequence is incorrect.
JR • Hitec • Futaba • New KO • Airtronics Z
JR, Hitec, Futaba, new KO, & Airtronics Z receivers do not need input
harness re-wiring.
Airtronics Z receivers have blue plastic cases & new KO
cases have tabs on the input harness openings as in
Figure 1
.
• Plug one end of the input signal harness into the
THROTTLE CHANNEL (#2)
of receiver with the
BLACK wire toward the outside edge
of receiver case.
• Plug the other end of the input harness into 3-pin header on the front edge
of the ESC’s circuit board with the
WHITE wire toward the left side
of the
ESC
(refer to pin-out label on case)
.
Old-style KO • Old-style Sanwa/Airtronics
If you have an older KO or Sanwa/Airtronics, you must change the se-
quence of the ESC’s input harness wires--
Old Sanwa/Airtronics cases are
black color & Old KO cases do not have tab openings, as in
Figure 2
above.
• Using a small flat blade screwdriver,
remove the red & black wires
from the
plastic housing at the receiver end of the input harness as in
Figure 3
below.
•
Interchange the red and black wires
in the plastic 3-pin connector housing
at the receiver end of the input harness.
• Insert modified end of the harness into the
THROTTLE CHANNEL (#2)
of
receiver with the
RED wire toward the outside edge
of receiver case.
• Plug the other end of the input harness into the ESC with the
WHITE wire
toward the ‘S’ (signal) marking
on the ESC’s case.

With ESC connected to (at least) a receiver & a charged battery pack:
1. TURN ON THE TRANSMITTER’S POWER
2. PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3. TURN ON THE SPEED CONTROL’S POWER
With transmitter throttle at neutral, and still
pressing the SET button
,
slide the ESC’s
ON/OFF switch
to ON position
.
4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5. RELEASE SET BUTTON AS SOON AS LED TURNS RED
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until the
green status LED
turns solid green
.
Note: Motor will not run during programming even if connected.
7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKES
Hold it there until the
green status LED
blinks green
.
8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
Red status LED
will
turn solid red
, indicating that speed control is
at neutral and that proper programming has been completed.
NOTE: If transmitter settings are changed, One-Touch Programming must be
repeated. If you experience any problems, turn off ESC & repeat One-Touch.
REMEMBER: Whenever One-Touch set-up is performed, ESC
automatically reverts to Throttle Profile #1.

Be sure to position the ESC with the power wires away from other
electronics & moving parts in the vehicle. Select a location that allows
airflow through heat sinks--
If the ESC gets good air flow, it will run cooler;
and that means it will be more efficient!
1. MOUNT ESC IN THE VEHICLE
using the included double-sided tape
.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery,
& servo as possible--these components all emit RF noise when throttle is applied.
On graphite or aluminum chassis vehicles, it may help to place receiver on
edge with crystal & antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top
of antenna mast (cutting or coiling excess antenna wire will reduce radio range).
2. MOUNT POWER CAPACITOR IN THE VEHICLE
using the included double-
sided tape, or secure it to part of the vehicle with a tie-wrap. The Power
Capacitor can also be tie-wrapped along the battery power wires.
If the Power Capacitor becomes dented or damaged, ESC failure
can occur--replace damaged Power Capacitors immediately.
3. INSTALL ON/OFF SWITCH
using a screw or the included double-sided
tape. Position in the vehicle where it will be easy to access.
If you have any problems with Step 4, adjust transmitter as follows
and then repeat One-Touch programming in Step 4:

The ESC is equipped with
4 user-selectable Throttle Profiles
to choose from:
PROFILE #1:
Forward, brakes, & reverse.
PROFILE #2:
Forward & brakes only.
PROFILE #3:
Forward, brakes, & reverse.
PROFILE #4:
Forward & brakes only.
NOTE:
ESC is factory set to Throttle Profile #1.
selecting throttle profile
:
With ESC on & connected to a charged battery (transmitter ON or OFF):
1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER
To avoid possible radio interference from other transmitters, remove
the ESC’s input signal harness from the receiver.
2. PRESS & HOLD THE ESC’S ONE-TOUCH SET BUTTON
Continue to hold SET button
on ESC
until both LEDs turn on
.
3. RELEASE SET BUTTON AS SOON AS BOTH LEDs COME ON
Once released, the 4 status LEDs will flash to indicate what Throttle
Profile is currently selected
. The number of times the LEDs flash
indicates the Throttle Profile selection
(1 of 4)
.
4. QUICK PRESS
(& release)
SET BUTTON TO CHANGE SELECTION
Each press will change to the next consecutive Throttle Profile.
*** Note: there is a time constraint during this selection process. ***
5. ESC STORES SELECTION & EXITS TO NEUTRAL
If SET button is not pressed for 3 seconds,
ESC stores selected Profile
into memory & the red LED will come on solid. The speed control
is at neutral & is ready to go.
NOTE: Whenever One-Touch set-up is performed, ESC reverts to Throttle Profile #1.

1. MOTOR CAPACITORS
Electric motors generate RF noise that causes interference. The included
0.1µF (50V) non-polarized, ceramic capacitors must be used on all motors
to reduce motor noise & prevent ESC damage.
Note: Some motors come with capacitors built-in. If your motor
only has two capacitors, you need to install a capacitor between the
positive & negative motor tabs––If you experience radio interference
when using only built-in capacitors, install external ones.
Solder 0.1µF (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (–) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (–) motor tab & GROUND tab*.
*If motor has no ground tab (below), solder the capacitors to motor can.
Negative (–) motor tab
**NO SCHOTTKY DIODE**
0.1µF Capacitors
Positive (+) motor tab
Ground / motor can
Extra 0.1µF capacitors are available in Novak kit #5620.
2.
DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible ESCs (including
brushless). Schottky diode usage will damage the ESC & void warranty.
If you are going to use connectors on the ESC’s motor wires, we highly
suggest Dean’s Ultra plugs or other low-loss connectors--do not use
crimp type connectors.
Note: If you plan to change the battery connector,
be aware that this can void the warranty if not done properly.
To prevent possible cross-connection of motor and battery wires:
• Use connectors that cannot be plugged in backwards. Reverse voltage
will damage the ESC and void warranty.
• Use a female connector on battery packs to avoid shorting.
For additional information on connector usage, visit our website.
connector usage
3. FACTORY-INSTALLED POWER CAPACITOR REQUIRED
The ESC comes with a factory-installed Power Capacitor, and it MUST
be used for proper operation and protection.
If Power Cap. becomes dented or damaged, ESC failure can occur
--replace immediately
.
Longer Power Capacitor wires will decrease performance
.
4. SOLDER MOTOR POWER WIRES TO MOTOR
a.
Cut the ESC’s
BLUE & YELLOW
silicone motor power wires to the
desired length, and strip 1/8-1/4” of insulation from the end of each
wire. Tightly twist the exposed strands of wire.
b.
Solder the ESC’s
BLUE
motor wire to the
motor’s negative (–) tab
.
c.
Solder the ESC’s
YELLOW
motor wire to the
motor’s positive (+) tab
.
6. CONNECT SPEED CONTROL TO BATTERY PACK
Connect the ESC’s Tamiya-style JST battery connector to a charged 4
to 7 cell
(1.2VDC/cell)
battery pack (or 2-cell Li-Po pack). Connector
can also be changed to a different type, or ESC can be hard-soldered
directly to battery pack.
FIGURE 4
using a receiver battery pack
Your new speed control has a built-in BEC (battery eliminator circuit), and you do
not need to use a separate receiver battery pack, however if you are planning to use
one to power the electronics you need to do the following:
1.
Plug the external 5 cell (1.2VDC/cell) receiver battery pack into the battery
slot of the receiver.
2.
Leave the
ESC’s ON/OFF switch
in the
OFF
position, and
use receiver battery
pack’s ON/OFF switch
to turn the
system power on and off
––Do not use the
ESC’s switch.
