NOT ALL TRANSMITTERS HAVE THESE ADJUSTMENTS

impact track guide

proper gear selection

4-2013#55-1730P-1 Rev.2

Motor operating temperature is the ONLY

way to properly set vehicle gearing

The Motor and Speed Control should not exceed

160°F MAX at any time during run!

Change the gearing to avoid overheating!

DO NOT FREE-REV MOTOR

Free-running your brushless motor in a no-load condition can cause rotor failure

& ESC transistor damage that will not be covered by the product’s warranty.

Because of the potential danger of overheating, ESC/motor damage & failure,

you must start with VERY small pinion sizes and check ESC & motor

temperatures at multiple times throughout the initial runs. This is the only

way to ensure that you are not causing excessive heating.

If ESC & motor temperatures remain low & stable, you can slowly increase

the pinion size while again monitoring the temperatures to determine the

safe gearing for your vehicle, motor, and climate/track conditions. Because

these variables can change or be modiﬁed, you MUST continually monitor

ESC & motor temperatures to protect your electronics from damage.

Transmitter adjustments may not be needed to operate this ESC, however,

if you have any problems with ONE-TOUCH PROGRAMMING, adjust the

transmitter as follows and repeat the ONE-TOUCH PROGRAMMING step.

THROTTLE CHANNEL ADJUSTMENTS

Set HIGH ATV or EPA to 100% setting. [amount of throw at full throttle]

Set LOW ATV, EPA, or ATL to 100% setting. [amount of throw at full brakes]

C. Set EXPONENTIAL to zero setting. [throttle channel linearity]

Set THROTTLE CHANNEL REV. SWITCH to either position.

E. Set THROTTLE CHANNEL TRIM to middle setting.

[adjusts neutral position/increases or decreases coast brakes]

Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 50%

throttle and

50% brake throw–best for reversible ESCs.

[adjusts trigger throw electronic/digital pistol-grip transmitters]

Set MECHANICAL TRIGGER THROW ADJUSTMENT to position

with 1/2

throttle and 1/2 brake throw.

transmitter adjustments

With the ESC connected to (at least) a charged battery pack, the receiver, and the

brushless motor’s sensor harness:

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.

CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON

5. RELEASE SET BUTTON AS SOON AS LED TURNS RED

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-BRAKE/REVERSE

Hold it there until the green status LED blinks green.

8. RETURN TRANSMITTER THROTTLE TO NEUTRAL

The red status LED will turn solid red, indicating that speed control is at neutral and

that proper programming has been completed. White LED may also be on and blinking,

indicating that Dynamic Timing Advance is OFF and the timing is set to a level of 0%.

If transmitter settings are changed, the One-Touch Programming must be repeated.

If you experience any problems, turn off ESC and repeat One-Touch.

NOTE:

The speed control will NOT revert back to the factory-default settings when the

One-Touch Programming is performed. Refer to ‘Data Reset’ in Custom Programming.

thermal protection circuitry

To conform to ROAR’s Sportsman Class racing rules and help race organizers

monitor driver compliance in non-timing race classes, we have included a

feature in this speed control that indicates when the ESC has its electronic

motor timing advancement feature de-activated.

At all times when the speed control is powered on and the Dynamic Motor

Timing is turned OFF (electronic motor timing advancement is set to zero), the

ESC’s white status LED will ﬂash during normal operation.

Due to the nature of timing advance speed controls, motor tolerances &

settings, vehicle performance, and track conditions, it has become virtually

impossible to provide installation and operation recommendations that

will allow you to use these speed controls and motors at their highest

performance levels without the potential for unwanted damage.

You must, use extreme caution when setting up these electronics and

carefully test your application to avoid overloading and overheating

either the speed control or the motor.

These are racing electronics used

in racing conditions, and therefore damage as the result of excessive

overheating will not be covered under the product’s factory warranty.

Electronic motor timing advancement can generate extrememly high speeds and

result in an uncontrollable vehicle. Use caution when operating vehicle and do not

operate around other people or in an unsafe manner to avoid injuries or damage.

The Hall Sensor Test diagnostic feature in this ESC allows you to easily check

the sensors in the brushless motor connected to the ESC to determine if they

are operating normally. This will help you pinpoint the cause of problems in

your system, and hopefully reduce the down time and expenses associated with

sending your product in for service when you can resolve the issue yourself.

To access this feature, simply follow these steps:

1. Follow the steps in the ‘CUSTOM PROGRAMMING OPTIONS’ section

to access the Hall Sensor Test option via the ESC’s SET button.

2. Slowly rotate the motor’s output/pinion shaft. If motor is installed in

a vehicle, slowly rotate the drive train so that the motor also rotates.

3. The status LEDs on the speed control should cycle through illuminating

the BLUE, YELLOW, and RED status LEDs.

If the BLUE, YELLOW, and RED LEDs light up one after another as the motor’s

shaft is rotated, the Hall Sensors in the motor are operating normally.

If any one of the BLUE, YELLOW, or RED status LEDs do not light while rotating

the motor’s shaft, there is a either a problem with the Sensor Harness Cable

(or its connections either at the motor end or the ESC end) or with the actual

Hall Effect Sensors in the motor’s timing section.

If your motor has a user-replaceable double-ended sensor harness, replace

it with another one to determine if this is this source of the problem. If, after

replacing the harness, all three of the LEDs still do not light up, it would

appear that one of the sensors inside the motor has been damaged--replace

the timing section of your motor, or if your motor is not user-rebuildable,

send it in the manufacturer for the appropriate service.

This ESC features Novak’s Smart-Stop Voltage Cut-Off Circuitry built-in, and

when used properly will allow you to safely use 2S LiPo (Lithium Polymer)

batteries, without letting the battery’s cells drop below their critical safety

voltage which causes internal damage. ESC does NOT cut off 1S packs.

The default in the ESC is LiPo voltage cut-off is turned ON. If using NiMH or

NiCd cells, you will need to switch this feature off.

Note: The speed control will NOT revert to the LiPo ON default

setting when the One-Touch Programming is performed.

DO NOT USE LiPo BATTERIES WITH VOLTAGE CUT-OFF TURNED OFF

temperature monitoring

With the higher performance of brushless systems, undesirable radio system

noise may occur when used with lower quality radio systems. 2.4GHz radio

systems are the best to use. FM radio systems are acceptable, as long as

the system is high quality. AM radio systems are NOT recommended.

Best to use

2.4 GHz

OK to use

Do not use

GOOD QUALITY RADIO SYSTEM SUGGESTED

This speed control has a built-in diagnostic temperature monitoring feature

that lets you quickly check the ESC’s operating temperature at any time.

While connected to a battery and powered ON, simply tap the ESC’s SET

button and one of the on-board LED lights will ﬂash 4 times to indicate the

operating temperature of the speed control.

WHITE ﬂashing LED = normal operating temp--under 135°F (57°C).

BLUE ﬂashing LED = medium operating temp--136-147°F (58-64°C).

YELLOW ﬂashing LED = hot operating temp--148-167°F (65-75°C).

GREEN ﬂashing LED = hotter operating temp--168-194°F (76-90°C).

RED ﬂashing LED = hottest operating temp--195-215°F (91-102°C).

You are now pushing the ESC extremely hard and should be very

careful to avoid overheating and possible thermal shut-down.

All LEDs ﬂashing = DANGEROUS operating temp--216-239°F (103-115°C).

Your ESC is now about to thermally shut-down.

---Reduce the pinion size to avoid overheating and potential ESC damage---

This ESC’s temperature overload protection will turn off the Dynamic Timing

Advance feature and limit the power to the motor in an attempt to prevent

thermal overloading of the ESC. While this feature can not guarantee the

survival of the ESC when subjected to conditions that produce excessive heating

of the electronics, it does provide you a tool to help avoid extensive damage.

f you notice a signiﬁcant decrease in performance of your brushless

system during a run, immediately check the ESC & motor temperatures.

Reduce gearing or ESC timing settings to lower temperatures!

Note: The thermal protection circuitry can be triggered by heavy BEC loading

from

high-power servos

An external BEC or receiver pack can solve this problem

and allow the thermal protection to provide maximum security for the ESC!
