ESC PROGRAMMING PROCEDURE

1. 

Power ON the transmitter and set the transmitter’s throttle endpoint travel to maximum 
and the throttle trim to the center position.

2. 

Hold the throttle trigger at full throttle, then power ON the ESC.

3. 

Continue holding the throttle trigger at full throttle until a beep sounds and both red  
and green LEDs flash, then release the throttle to neutral.

4. 

The ESC is now in programming mode. The ESC will cycle through its programmable 
features in this order:

 - A.  Green LED only: Change Battery Chemistry Type: Ni-MH or Li-Po
 - B.  Red LED only: Transmitter/ESC Endpoint Calibration
 - C.   Red + Green LED: Change ESC Running Mode: Forward/Reverse (Smart Brake)  

or Forward Only (Brake)

5. 

Move the throttle trigger to full throttle and back to neutral at A, B or C in order to 
execute the setting task:

A.   Change Battery Chemistry Type: Ni-MH or Li-Po

The respective LED will indicate the current battery type for 4 seconds:

 -Solid Green LED: Ni-MH
 -Solid Red LED: Li-Po

a. 

Move the throttle trigger to full throttle and return to neutral within  
the 4 seconds. A beep will sound and the respective LED will indicate  
the updated battery type.

b. 

To change back to the previous battery type, repeat the step above  
within 4 seconds of the beep.

c. 

Both red and green LEDs will flash 3 times with 3 beeps.

d. 

Power OFF the ESC and then power ON the ESC to return to normal operation.

B.  Transmitter/ESC Endpoint Calibration

After executing the setting task, the green LED will flash as you release the throttle 
trigger to neutral. Once neutral is reached, a beep will sound and the green LED  
will glow solid for 1 second. The red LED will begin to flash.

a. 

Move the throttle trigger to full throttle and hold it until a beep sounds and  
the red LED glows solid for 1 second. Release the throttle trigger to neutral  
and the red LED will glow solid while the green LED will begin to flash.

b. 

Move the throttle trigger to full brake/reverse and hold until a beep sounds  
and the green LED glows solid.

c. 

Release the throttle trigger to neutral. Both red and green LEDs will flash  
3 times with 3 beeps.

d. 

Power OFF the ESC and then power ON the ESC to return to normal operation.

The green LED will indicate the currently selected ESC running mode for 4 seconds:

 -Green LED Solid: Forward/Reverse (Smart Brake)
 -Green LED Flashing: Forward Only (Brake)

a. 

Move the throttle trigger to full throttle within the 4 seconds to select the  
next ESC mode. A beep will sound and the green LED will indicate the new  
ESC running mode.

b. 

To change back to the previous mode, repeat the step above within 4 seconds  
of the beep.

c. 

Both red and green LEDs will flash 3 times with 3 beeps.

d. 

Power OFF the ESC and then power ON the ESC to return to normal operation.

 

At any time that the ESC is powered and the transmitter is at neutral,  
the green LED will indicate the current ESC running mode:

 -Green LED Solid: Forward/Reverse (Smart Brake)
 -Green LED Flashing: Forward Only (Brake)

GEARING

COMMENTS

14T

62T

Ni-MH

OK

This is the stock gearing. If you use a 2S–3S Li-Po, you will need to gear down,  
or you will overheat the motor.

12T

62T

2S Li-Po

OK

This gearing is optimal for a 2S Li-Po.

11T

62T

3S Li-Po

OK

This gearing is optimal for a 3S Li-Po.

CHANGING THE PINION/GEAR RATIO

Your vehicle comes with the 14T pinion gear installed for the  
included 6C Ni-MH battery. If you want to use a 2S–3S Li-Po  
battery, refer to the Gearing Chart for the proper gearing.

1. 

Remove the 6 screws securing the gear cover and remove  
the gear cover.

2. 

Loosen the motor screws and slide the motor back. 

3. 

Loosen the setscrew and remove the installed pinion gear.

4. 

Place the new pinion on the end of the motor shaft so the 
setscrew is located over the flat on the shaft.

5. 

Position it so the teeth line up with the spur gear and  
secure by tightening the setscrew.

6. 

Tighten the motor screws and reinstall the gear cover.

SETTING THE GEAR MESH

The gear mesh has already been set at the factory. Setting it  
is only necessary when changing motors or gears. Proper gear 
mesh (how gear teeth meet) is important to the performance 
of the vehicle. When the gear mesh is too loose, the spur gear 
could be damaged by the pinion gear of the motor. If the mesh  
is too tight, speed could be limited and the motor and ESC  
will overheat.

1. 

Remove the 6 screws securing the gear cover and  
remove the gear cover.

2. 

Loosen the motor screws and slide the motor back.

3. 

Put a small piece of paper between the pinion and  
spur gears.

4. 

Push the gears together while tightening the motor screws.

5. 

Remove the paper. Check the mesh at 3–5 different  
locations around the spur gear for a small amount  
of movement.

6. 

Reinstall the gear cover.
