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 Module is installed and MUST be used

with your ESC. Failure to use Power Capacitor will result in higher ESC

operating temperatures & possible thermal shut-down.

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.

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.

trouble-shooting guide

Steering Channel Works But Motor Will Not Run

• Red status LED blinking when throttle is applied. Check motor sensor harness

connection at ESC (make sure all metal sockets are fully inserted into the connector’s

plastic housing)––check for damaged wires.

• Red status LED on solid & Green LED blinking. Check input signal harness & motor

sensor harness connections at ESC. Check input signal harness wiring sequence &

connection at throttle channel of receiver. Check throttle channel operation with servo.

Motor sensor harness connected while in Brush-Mode––disconnect sensor harness.

• 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 Steps 4 & 5.

• Red status LEDs toggling. Li-po Safety Cut-Off has been activated.

• 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.

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

Motor and Steering Servo Do Not Work

• Check wires, receiver signal harness wiring & color sequence, radio system, crystals,

battery/motor connectors, & battery pack.

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

• Possible internal damage––Refer to Service Procedures.

Speed Control Runs Excessively Hot

• Gear ratio too low––Increase gear ratio (see ‘GEAR SELECTION’).

Model Runs Slowly/Slow Acceleration

• Gear ratio too high––Reduce gear ratio (see ‘GEAR SELECTION’).

• Check battery connectors––Replace if needed.

• Incorrect transmitter/ESC adjustment––Refer to Steps 4 & 5.

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

ESC Is Melted Or Burnt/ESC Runs With Switch Off

• Internal damage––Refer to Service Procedures.

If you are planning to use an external receiver battery pack to power the elec-

tronics 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 & use receiver pack’s

ON/OFF switch to turn system power on and off––Do not use the ESC’s switch.

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/PROGRAMMING BUTTON

Note: The GTB’s One-Touch/Programming button is combined with the ON/OFF

switch on the Remote Power Programming Switch harness.

3. TURN ON THE SPEED CONTROL’S POWER

With transmitter throttle at neutral, and still pressing the One-Touch button,

slide the ESC’s ON/OFF switch to ON position.

4. CONTINUE HOLDING BUTTON UNTIL RED LED COMES ON

5. RELEASE ONE-TOUCH 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.

For proper ESC operation, adjust transmitter as follows:

A. Set HIGH ATV or EPA to maximum setting.

[amount of throw at full throttle]

B. Set LOW ATV, EPA, or ATL to maximum setting.

[amount of throw at full brakes]

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

D. Set THROTTLE CHANNEL REV. SWITCH to either position.

E. Set THROTTLE CHANNEL TRIM to middle setting.

[adjusts neutral position/increases or decreases coast brakes]

F. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 70% throttle and

30% brake throw (or 7:3) for Forward & Brake only Profiles, and 50%

throttle and 50% brake throw (or 5:5) for Profiles with reverse.

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

G. Set MECHANICAL TRIGGER THROW ADJUSTMENT

(if radio has it)

to position

with 2/3 throttle and 1/3 brake throw for Forward & Brake only Profiles,

and position with 1/2 throttle and 1/2 brake throw for Profiles with Reverse.

[adjusts trigger throw on mechanical/analog pistol-grip transmitters]

Mount ESC with power wires away from other electronics & moving parts.

Select a location that allows good airflow through and around the heat sink

and cooling fan--Good air flow allows ESC to run cooler and more efficient!

1. MOUNT ESC IN VEHICLE using the included double-sided tape. Be sure

the receiver & antenna are mounted as far from ESC, power wires, battery,

& servo as possible--these components all emit RF noise when the 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 the antenna as close to the receiver as possible--trail any excess wire off the top

of the antenna mast (cutting or coiling the excess antenna wire will reduce radio range).

2. SECURE POWER TRANS-CAP MODULE IN VEHICLE

Use the included double-sided tape to mount the Power Trans-Cap

Module to the chassis with the included double-sided tape. Module can

also be tie-wrapped to the power wires or other part of chassis or shock

tower with the included tie-wraps.

3. INSTALL REMOTE POWER PROGRAMMING SWITCH with the included

double-sided tape where it will be easy to access for turning the electronics

on & off and also for programming the GTB’s throttle profiles or switching

between Brushless and Brush-Modes.
