STEP 4
TRANSMITTER ADJUSTMENTS
For proper ESC operation adjust transmitter as follows:
1. Set HIGH ATV or EPA to maximum setting.
[Controls amount of throw from neutral to full throttle]
2. Set LOW ATV, EPA, or ATL to maximum setting.
[Controls amount of throw from neutral to full brakes]
[Reduce this after programming to reduce amount of brakes]
3. Set EXPONENTIAL to zero.
[Controls the linearity of the throttle channel]
4. Set THROTTLE CHANNEL TRIM to middle setting.
[Adjusts neutral position/Increases or decreases coast brakes]
5. Set CHANNEL REVERSING SWITCH to either position.
6. Set ELECTRONIC TRIGGER THROW ADJUSTMENT
to 70% throttle and 30% brake throw (or 7:3).
[Adjusts pistol-grip transmitter's throttle trigger throw]
7. Set MECHANICAL TRIGGER THROW ADJUSTMENT
to position with 2/3 throttle and 1/3 brake throw.
[Adjusts pistol-grip transmitter's throttle trigger throw]
STEP 5
SPEED CONTROL PROGRAMMING
Before beginning this step, the speed control should be
connected to the receiver and to a charged 4 to 6 cell
battery pack, and the transmitter should be adjusted.
1. CONNECT THE BATTERY
2. TURN ON TRANSMITTER THEN THE SPEED CONTROL
Slide the
switch to the
ON/OFF
ON
3. PRESS AND HOLD ESC'S 1-TOUCH BUTTON
With the transmitter throttle in the neutral position,
press and hold the
button on the speed control
SET
until the status
LED
turns solid red.
4. RELEASE ESC'S 1-TOUCH BUTTON
5. PULL THROTTLE TO FULL-FORWARD POSITION
Hold it there until the status
LED
NOTE: The motor will not run during programming even
if it is connected to the speed control.
6. PUSH THROTTLE TO FULL-BRAKE POSITION
Hold it there until the status
LED
7. RETURN TRANSMITTER THROTTLE TO NEUTRAL
The status
LED
will turn solid red, indicating that the
throttle is in the neutral position and also that proper
programming has been completed.
The speed control is programmed and ready to race!
If transmitter settings are changed, it will be necessary
to complete the programming sequence once again.
If you experience any problems during programming,
turn off the speed control and repeat programming.

STEP 6
THROTTLE PROFILE SELECTION
The Atom allows you to choose between three user-selectable
throttle profiles that are programmed at the factory. This chart
gives the specifics of each profile:
1
2
Drag Brake
3
**
Experiment with each profile to determine which works best for you!
1. TURN ON THE TRANSMITTER
Keep receiver and
antenna away
2. TURN ON THE SPEED CONTROL
from motor,
3. PRESS & HOLD ESC'S 1-TOUCH BUTTON until the status
servo, battery,
and power wires.
LED turns solid green. The LED will first turn red, then a
few seconds later it will turn green.
4. RELEASE 1-TOUCH BUTTON and then the status LED will
begin to blink red. The number of times the LED blinks
indicates the profile number selected.
5. PRESS & RELEASE 1-TOUCH BUTTON TO SELECT PROFILE
Each press will change to the next consecutive profile number.
NOTE: After profile #3, the sequence begins again at profile #1.
6. If 1-TOUCH button is not pushed for about five seconds,
the ESC LOADS THE SELECTED PROFILE INTO MEMORY,
and the status LED turns solid red, indicating that the speed
control has exited the profile selection mode and is in neutral.
The Atom can store a custom 4th profile that is created with the
optional software in the Millennium Pro (#4490) & the Pit Wizard
(#1035). Once a custom profile has been created and down-
loaded into the ESC, there will be four profiles to choose from.
Both programming devices come with complete details on creating
your own custom profiles and give you the ability to modify the
following parameters: Neutral, Full Throttle, & Full Brake Positions,
Dead Band Value, Drag Brake Value, Drag Brake Frequency*, Drive
PWM Frequency*, Minimum Drive Value, Brake PWM Frequency*,
and Drag Brake Toggle.

STEP 7
MINIMUM BRAKE ADJUSTMENT
The BRAKE pot on the Atom speed control allows you to adjust
the percentage of total braking power applied with the initial
trigger movement in the brake direction. Refer to the illustration
above for indication of Minimum Brake Value.
Note: In profile 2 the Atom's pot adjusts the amount of drag brake.
• Turning BRAKE pot clockwise, increases amount of minimum
braking up to a maximum of 75% of the total brake force.
• Turning BRAKE pot all the way counter-clockwise, sets the
amount of minimum braking at the lowest value of 0.39%,
or 1/256th (one step) of the total brake force.
RECEIVER BATTERY PACK
The Atom speed control should not require an external
receiver battery pack for most racing situations. The built-in
Radio-Priority Circuity™ provides complete control of the
position.
steering servos even after the main battery pack has 'dumped'
and can no longer provide the power required to turn the
motor. However, applications with multiple high-power servos,
and some 4-cell set-ups may require an external receiver battery
pack to prevent overloading or underpowering of the speed
control's voltage regulator.
1. Plug the external 5 cell nickel cadmium receiver battery
pack into the battery slot of the receiver.
turns solid green.
2. Leave the speed control's ON/OFF switch in the OFF position.
This switch is not used with this configuration.
3. Use the ON/OFF switch on the external receiver battery
pack to turn the system power on and off.
blinks green.
Note: If using a FET servo with an external receiver battery pack, the
separate power wire from the servo must be connected to the red or
positive servo wire. For this application do not use blue wire from ESC.
FET SERVO CONNECTION
The Atom speed control is wired for connecting a FET servo
that requires seperate power connection. The fourth wire from
the servo is connected to the small blue 24 gauge silicone
wire exiting the speed control along with the signal and switch
harnesses. This wire supplies 6 volts DC to the servo, and is
controlled by the ESCs ON/OFF switch.
Be sure to install the 10 H inductor (supplied with servo) in
series with the blue FET wire as shown below.
Blue FET servo wire
from speed control
NOTE: Do not allow the blue FET servo wire to contact the battery
or any condutive surfaces, as this may cause damage to the speed
control and will void the warranty.

TROUBLE-SHOOTING GUIDE
This section describes possible speed control problems,
causes, and solutions.
Steering Channel Works But Motor Will Not Run
• Speed control has thermally shut down––Allow ESC to
cool down––Use milder motor or smaller pinion gear.
• Check motor connections. Check motor and brushes.
• Make sure ESC is plugged into the throttle channel of
receiver. Check throttle channel operation with a servo.
Check wiring color sequence of receiver signal harness.
OFF
• Possible internal damage––Refer to Service Procedures.
ON
OFF
Receiver Glitches/Throttle Stutters During Acceleration
• Motor capacitors broken or missing––Refer to Step 3.
• Receiver or antenna too close to speed control, power
wires, battery, or motor––Refer to Step 2.
• Bad connections––Check wiring and connectors.
• Motor brushes worn––Replace brushes.
• Excessive current to motor––Use a milder motor or a
smaller pinion gear.
Motor and Steering Servo Do Not Work
• Check wires, receiver signal harness wiring and color
sequence, radio system, crystals, battery and motor con-
nectors, and battery pack.
• Possible internal damage––Refer to Service Procedures.
Model Runs Slowly / Slow Acceleration
• Check motor and battery connectors––Replace if needed.
• Bad battery or motor––Check operation with another.
• Incorrect transmitter or speed control adjustment––
Refer to Steps 4 and 5.
• Optional external Schottky diode installed backwards
or damaged––Refer to Step 3.
Motor Runs Backwards
• Motor wired backwards––Check wiring and reverse.
• Backwards motor timing––Reverse motor end bell.
ESC Is Melted Or Burnt/ESC Runs With Switch Off
• Internal damage––Refer to Service Procedures.
