ATTENTION: Proper gearing is essential to getting the most performance from your GTB
and your brushless motor system when operating in the Brushless-Mode.

proper gear selection
As a general rule with the Velociti 5.5R Brushless motor on 6 cells, start
with a 3 tooth lower pinion gear than you would normally use with a
low-turn brush-type motor.
As a general rule with the Velociti 6.5R Brushless motor on 6 cells, start
with a 2 tooth lower pinion gear than you would normally use with a
low-turn brush-type motor.
*For other motors, refer to the motor's included instructions for gearing recommendations.
Because of the broad power band of brushless, you can go 1 to 3 teeth higher
pinion than the above recommendations for more top speed, but note that
that going 3 or more teeth higher will produce excessive ESC heating. Be sure
to check the operating temperature of ESC after making gearing adjustments.
The GTB ESC is designed to operate comfortably from 160ºF-180ºF
with motor temperatures also around 160-180ºF.
than typical brush-type ESC)
If you had a low turn modified brush-type motor in the vehicle before
switching to the GTB system, and you do not change gearing, you will be
over-geared and the vehicle will have slower acceleration!
Start within these final drive ratio ranges in the vehicle:
8.75–9.25 : 1

7.75–8.5 : 1
Velociti 6.5R in Touring Cars
11.5–12.0 : 1
10.5–11.0 : 1
13.0 : 1
Velociti 5.5R in Off-Road Stadium Trucks
12.3 : 1

Higher final drive ratios will give longer run time at the expense of top speed. Lower ratios will
result in higher ESC temperatures--too low may result in overheating & thermal shut-down.

With ESC off & connected to a charged battery (transmitter ON or OFF):
1. REMOVE BRUSHLESS 6-WIRE SENSOR HARNESS FROM ESC
2. DISCONNECT BRUSHLESS MOTOR FROM ESC
3. PRESS & HOLD ESC'S ONE-TOUCH/SET BUTTON
4. TURN ON THE SPEED CONTROL'S POWER
While still pressing SET button, slide ESC's ON/OFF switch to ON position.
5. CONTINUE PRESSING UNTIL BLUE & RED LEDs COMES ON
Note: you will continue holding past the Red LED One-Touch indicator.
6. RELEASE BUTTON AS SOON AS BLUE & RED LEDs COMES ON
Blue & Red LEDs flash 9 times, then turn on solid after a few seconds.
7. QUICK PRESS
(& release)
ESC changes modes, and the Green LED will flash for a few seconds (with
Blue & Red LEDs still on solid) to let you know you have changed modes.
Note: there is a time constraint during this selection process.
8. ESC EXITS MODE SELECTION & RETURNS TO NEUTRAL
9. CONNECT BRUSH-TYPE MOTOR TO ESC
Refer to BRUSH-TYPE MOTOR portion of STEP 3 on main instructions
IMPORTANT PRECAUTION: Never connect a brushless motor's 6-wire sensor harness to ESC when wired to a brush-type motor!
If ESC is powered on while in Brushless-Mode, and is connected to Brush-type motor {phase wir es shorted together} & a battery pack, a 6-wire
brushless motor's sensor harness is connected to ESC, and ESC receives a transmitter's throttle signal, severe ESC damage will occur.

1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER
To avoid possible radio interference from other transmitters, remove
the ESC's input signal harness from the 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 the Blue, Blue & Amber, Blue & Green,
and then the Amber LED programming indicators in the ESC's software.
3. 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 5).
4. QUICK PRESS
Each press will change to the next consecutive Throttle Profile.
Profile 5 in Brushless-Mode, the sequence begins again at Profile 1)
Note: there is a time constraint during this selection process.
5. 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.

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.
