WATER & ELECTRONICS DON’T MIX!

Never allow water, moisture, or other foreign materials to get inside ESC, motor,

or on the PC Boards.

Water damage will void the warranty!

NO SCHOTTKY IN BRUSHLESS-MODE!

Schottky diodes must NOT be used when using ESC in Brushless-Mode (Schottky

diodes are never used with reversible ESCs, including brushless).

Schottky diode usage in Brushless-Mode will damage ESC & void warranty.

DISCONNECT BATTERIES WHEN NOT IN USE

Always disconnect the battery pack from the speed control when not in use to

avoid short circuits and possible fire hazard.

4 TO 7 CELLS OR 2-CELL Li-Po ONLY

If using Ni-Cd or Ni-MH batteries,

NEVER use fewer than 4 or more than 7 cells

(1.2VDC/cell) in the vehicle’s main battery pack.

If using Li-Po batteries,

ONLY use a 2-cell (2S) pack for the vehicle’s main battery

& be sure the Li-Po Cut-Off programming option is turned

ON.

NOVAK BRUSHLESS MOTORS ONLY

The XBR Sport is designed for use with sensor-based Novak Brushless Motors.

You may replace with Novak sensored motors down to 8.5 turns.

NO REVERSE VOLTAGE!

Reverse battery polarity can damage ESC & void warranty. Disconnect battery

immediately if a reverse connection occurs.

POWER CAPACITOR REQUIRED

An external power capacitor is installed on ESC &

MUST be used. Failure to use

Capacitor will result in higher temperatures & possible thermal shut-down or damage.

TRANSMITTER ON FIRST

Always turn on the power of the transmitter first so that you will have control of

the vehicle when you turn it on.

GOOD QUALITY TRANSMITTER SUGGESTED

With the higher performance of brushless systems, undesirable radio system noise

may occur when used with lower quality transmitters (like some RTR radios).

DO NOT BUNDLE POWER & SIGNAL WIRES TOGETHER

RF noise in the power wires can adversely effect radio system performance.

INSULATE WIRES

Always insulate exposed wiring with heat shrink tubing or electrical tape to

prevent short circuits, which can damage ESC.

NO CA GLUE

Exposure to CA glue or its fumes can cause damage to internal components of

the speed control and result in premature failure.

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

factory default settings & the Throttle Profile reverts to #1 when in Brushless-Mode.

trouble-shooting guide

Steering Channel Works But Motor Will Not Run

Red & Green status LEDs on solid––Check input signal harness connections at ESC

and receiver. Check input signal harness wiring sequence––Refer to Step 1.

Red status LED on solid & Green LED blinking––Check motor sensor harness

connection. Possible internal motor damage.

Blue & Green status LEDs both blinking. Possible ESC shut-down due to locked

rotor detection––return throttle to neutral position to regain motor control––check

vehicle’s drive train for free operation.

Blue & Red status LEDs blinking. Possible ESC thermal shut-down––Check gear ratio

& free operation of drive train for possible overloading/ESC is being severely over-

loaded––allow system to cool & return throttle to neutral position to regain motor

control.

LEDs will continue to blink until system is cooled down.

Blue & Amber status LEDs blinking. Possible motor thermal shut-down––Check gear

ratio & free operation of drive train for possible overloading/motor is being over-

loaded––allow system to cool & return throttle to neutral position to regain motor

control.

LEDs will continue to blink until system is cooled down.

Blue & Green (Locked Rotor Detection), Blue & Red (ESC Thermal Shut-Down), or

Blue & Amber (Motor Thermal Shut-Down) status LEDs blinking. ESC may have

shut-down & ESC’s neutral point is too far off to sense that transmitter throttle

has been returned to neutral––Refer to Step 4.

• Possible receiver damage––Check operation with a different receiver.

• Possible internal damage––Refer to Service Procedures.

Receiver Glitches/Throttle Stutters During Acceleration

• Receiver or antenna too close to ESC, power wires, battery, or motor.

• Bad connections––Check wiring, connectors, & sensor harness.

• Low voltage to receiver––Try Glitch Buster capacitor on receiver (Novak part#5626).

• External Power Capacitor damaged/not installed––Replace Power Capacitor.

• Battery pack damaged or weak––Try a different battery pack.
