MAINTENANCE
SETTING THE GEAR MESH
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. Loosen the 2 motor screws (B).
2. Put a small piece of paper (C) between the pinion and spur gears.
3. Push the gears together while tightening the motor screws.
4. Rotate the gears to remove the paper. The gearing should move a
small amount.
5. Reinstall the gear cover.

ELECTRONIC SPEED CONTROL (ESC)
Programming: The ESC comes with two jumpers pre-installed in the
REV: ON and BATT: Li-Po configurations.
To disable reverse or change battery type to Li-Po, disconnect the jumper
from the default port and connect it to the desired port. Power off the
ESC, then power it back on.
If the jumpers are lost or not installed, the ESC will default to REV: ON
and BATT: Li-Po.
Operation
Tone
Start up
One short tone, followed by one long tone.
Low Voltage Cut-Off
When low voltage cuttoff is reached, the vehicle will slow and emit a continuous tone.
Low Voltage at Start Up
When a low battery is plugged in and powered on, the vehicle will emit two low tones and power off.
ELECTRICAL LAYOUT
For correct operation, Channels 1 and 2
must be used as shown in the wiring diagram.
The motor can be disconnected from the ESC
