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 flat surface. When
dropping the front of the vehicle, after the vehicle settles, make
sure the front arms are equal and parallel to the flat surface. Do the
same with the rear to make sure both arms are parallel with the flat
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 Identifier) code of a single specific 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.
