MOTOR CARE

• Seat the motor brushes by driving smoothly on a flat surface 

during use of the first battery charge.

• Prolong motor life by preventing overheating conditions. 

Undue motor wear results from frequent turns, stops and 

starts, pushing objects, driving in deep sand and tall grass, 

and driving continuously up hill. Not allowing motor to cool 

between runs can quickly diminish the performance of your 

vehicle. Allow adequate time for motor to cool to ambient 

temperature betweens runs for best vehicle performance.

• Over-temperature protection is installed on the ESC to 

prevent circuit damage, but cannot protect the motor from 

driving against heavy resistance.

RIDE HEIGHT ADJUSTMENT

Ride height is an adjustment that affects the way the vehicle 

jumps, turns and goes over bumps. Drop one end of the vehicle from 

approximately 3 inches (75 mm) in height onto a fl at surface. When 

dropping the front of the vehicle, after the vehicle settles, make 

sure the front arms are equal and parallel to the fl at surface. Do  the 

same with the rear to make sure both arms are parallel with the fl at 

surface. To adjust your ride height, either add or remove spring clips 

to achieve the desired ride height.

Lower the front ride height to increase steering. Lower the rear  ride 

height to increase traction but decrease steering.

INITIAL SETUP

SETTING THE GEAR MESH

A

B

C

The gear mesh has already been set at the factory. Setting the 

gear mesh is only necessary when changing motors or gears. You 

must remove the vehicle’s gear cover (A) to make this adjustment. 

Proper gear mesh (how the 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. Set the gear mesh by following these simple steps:

1. Remove 7 screws to remove the gear cover (A).

2. Loosen the 2 motor screws (B).

3. Put a small piece of paper (C) between the pinion and spur 

gears.

4. Push the gears together while tightening the motor screws.

5. Rotate the gears to remove the paper. The gearing should 

move a small amount.

6. Reinstall the gear cover.

FAILSAFE 

In the unlikely event that the radio connection is lost during use 

(possibly due to low transmitter batteries or distance between the 

receiver and transmitter), the receiver will hold the steering at the 

last command with no throttle.

If the receiver is powered on before powering on the transmitter, 

the receiver will enter this failsafe mode. When the transmitter is 

powered on, normal control is resumed.

Binding is the process of programming the receiver to recognize the 

GUID (Globally Unique Identifi er) code of a single specifi c transmitter. 

The included transmitter and receiver are bound at the factory. If you 

need to rebind, follow the instructions below.

1. Power off the transmitter and ESC.

2. Connect a fully charged battery pack to the ESC.

3. Press and hold the bind 

button while powering 

up the ESC. After

2 seconds the ESC will 

be in bind mode.

4. Release the bind 

button and power on 

transmitter.

5. Binding  is  complete 

when you hear three 

beeps from the ESC. 

You must rebind when binding the receiver to a different transmitter.

NOTICE: Do not attempt to bind the transmitter and receiver 

if there are other compatible transmitters in bind mode within 

400 feet. Doing so may result in unexpected binding.
