With ESC on & connected to a charged battery

IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER

To avoid possible radio interference, remove the ESC’s input signal harness

from the receiver--

Green LED will stay on to indicate no signal from receiver.

2. PRESS & HOLD THE ESC’S ONE-TOUCH SET BUTTON

Continue to hold SET button on ESC until all 4 LEDs turns on.

Note: You will continue holding past all the LED programming indicators in

the ESC’s software as shown in the ﬂow chart on back side of this sheet.

RELEASE SET BUTTON AS SOON AS ALL 4 LEDs COMES 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 Brushless

Throttle Proﬁle selection (1 of 3).

QUICK PRESS

Each press will change to the next consecutive Throttle Proﬁle. (After Proﬁle

3 in Brushless-Mode, the sequence begins again at Proﬁle 1)

Note: there is a time constraint during this selection process.

ESC STORES SELECTION & BEGINS TO EXIT PROGRAMMING

If SET button is not pressed for 3 seconds, ESC stores selected Proﬁle in

memory, exits to neutral & is ready to go. (LEDs turn off in a rolling motion

left to right, then Red LED turns on solid-signal present & Blue or Blue & Amber LEDs on if Drag or Min. Brakes above 0%)

Note: ESC reverts to factory default settings & Throttle Proﬁle #1 whenever One-Touch set-up is performed (reverts to Proﬁle #4 Brush-Mode if no brushless motor sensor harness is connected).

AuxilliAry FaN OUtput

The XBR features a set of power output pins for running auxilliary cooling fans, so you to can add fans to the motor, the ESC, or both, and they will switch on & off with the ESC’s power switch. These pins output 6.0 VDC

polarity of the fan power output pins. They are the 2 pins on the front edge

of the circuit board--Positive (+) is on the left, and Negative (–) is on the right.

The set of 3 pins behind them are for the user-replaceable input signal harness--The polarity of those is the same: Positive in the middle, Negative on the right, and the extra pin on the left is for the input signal.

The Novak 30x30x6mm clear cooling fan comes with the GTB ESC, and not only ﬁts the size of the XBR’s heat sink perfectly, it also comes with the connector already on it to match the pins on the XBR. Fans that do not have the proper connector on them will need a connector be soldered to the pins--

proper gear selection

Motor operating temperature is the ONLY

way to properly set the vehicle gearing

The motor should be 160-175°F MAX at end of run!

Change the gearing to avoid overheating.

General Gearing for 6-Cell Ni-MH or 2-cell Li-Po Use:

MOTOR PINION

EX8.5/SS8.5/SS5800

EX10.5/SS10.5/SS4300

EX13.5/SS13.5

If you do not change gearing after switching to brushless, you will be

over-geared and will have slow acceleration & excessive temperatures!

With the broad brushless power band, you can go 1-2 teeth higher pinion than listed above for more top speed, but remember going higher will produce excessive ESC & motor heating. Check the motor’s operating temperature after making any gearing adjustments--motors are designed to operate from 160ºF-175ºF.

1 tooth higher pinion than normally used on 13-17T brush motor

1 tooth higher pinion than normally used on 19T brush motor

2-3 teeth higher pinion than normally used on 27T brush motor

proFile adjustments

The following parameters are adjustable in the ESC’s software:

MINIMUM BRAKE (1 of 7 settings from 0 to 18%)--The amount of braking applied with the ﬁrst pulse of transmitter brake information.

Raising this setting starts the braking at a stronger/higher level.

DRAG BRAKE (1 of 7 settings from 0% {off} to 18%)--The amount of braking applied while the transmitter is at neutral. Also known as ‘coast’ or ‘auto’ brakes.

Raising this setting makes the motor slow down more without pushing

(With Drag Brakes on settings 2-10, the Minimum Brake value is the same as the Drag Brake value)

DEAD BAND (1 of 5 settings from 2 to 6%)--The space between Minimum Brake and Minimum Drive, with neutral in the middle.

MINIMUM DRIVE (1 of 5 settings from 1 to 12%)--The amount of forward drive applied with the ﬁrst pulse of transmitter throttle information.

the transmitter’s trigger into the brake/reverse direction.

Raising this setting will increase the ‘free play’, or distance your trigger

must move before forward drive or braking will begin.

Raising this setting makes the motor start at a stronger/higher

level so it takes off more aggressively from neutral.

Li-PO cUt-OFF circUitrY

When active Stop Li-Po Cut-Off Circuitry lets you safely use Lithium Polymer batteries by cutting off the ESC’s throttle output when a critical safety voltage is reached.

The circuitry constantly monitors the pack voltage. When it gets close to the critical safety voltage output as an early warning that the battery’s voltage is getting low and the throttle output will soon be completely shut off.

When the critical voltage is reached, the throttle output to the motor gets completely shut down to keep the voltage from dropping further

LEDs will alternately ﬂash & you still have steering control)

Smart-Stop circuitry shuts off throttle. Even though the pack’s voltage will rise

(after a short resting period) this is not good for Li-Po batteries--Reaching the critical safety voltage too many times can damage the cells.

THE SMART-STOP HAS SHUT DOWN THE THROTTLE OUTPUT THE FIRST TIME.

During power-up when the ESC is switched ON, the Amber & Red

LEDs will ﬂash together 3 times to indicate Li-Po Cut-Off is ACTIVE.

With the Li-Po Cut-Off turned ON & using Ni-Cd or Ni-MH cells, the circuitry will shut off the

ESC’s throttle output very early into the run, due to the dﬁferent characteristics of these batteries.

PLEASE NOTE: This page contains optional Advanced Programming items!

(but don’t worry, you can always reset factory defaults by performing the One-Touch programming again, so go ahead & experiment--that’s why the programming is in there, right?)

to custom program profiles:

Your transmitter can be either ON or OFF:

1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER

Remove input signal harness from receiver to avoid radio interference.

2. CONNECT SPEED CONTROL TO A CHARGED BATTERY PACK

3. SLIDE ESC’s ON/OFF SWITCH TO ‘ON’ POSITION

4. MAKE SURE THE THROTTLE PROFILE TO ADJUST IS ACTIVE

If you are not sure what proﬁle is selected, follow the procedures in ‘Throttle Proﬁle

Selection’ to check or select the desired proﬁle.

5. FOLLOW STEPS ON RIGHT SIDE OF THIS PAGE TO CUSTOMIZE ESC

You can adjust different parameters

speed control to perform & feel the way you like it.

Remember that you can not access the Brush-Mode

disconnecting the brushless motor’s sensor harness from the ESC.

Note: there is no time constraint during selection process of custom parameters.
