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

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 Velociti 5.5R in Touring Cars

7.75–8.5 : 1 Velociti 6.5R in Touring Cars

11.5–12.0 : 1 Velociti 5.5R in Off-Road Buggies

10.5–11.0 : 1 Velociti 6.5R in Off-Road Buggies

13.0 : 1 Velociti 5.5R in Off-Road Stadium Trucks

12.3 : 1 Velociti 6.5R in Off-Road Stadium Trucks

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 on & connected to a charged battery

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. (After
