1.Before Starting
2.While Operating
•Please read manual carefulyl (With a parent, guardian or a responsible adult if necessary).
•Any running area you choose must be dry. Do not run vehicle near any water or wet areas.
•Do not run on public streets. It is very easy to have the car run over or damaged by hitting obstacles
or other surfaces.
•Do not operate the car in tight confined places. The vehicle is very fast and will easily hit something.
•Do not run near people or animals. The car is very fast and could seriously injur someone.
•Do not operate the car at night. You will not be able to drive it safely.
3.Before Operating
•Make sure that all screws and nuts are properly tightened.
•Always use fresh batteries for your transmitter and receiver before running the car. If the radio does
not have full control of the car with steering, throttle and brake. Do not run it until corrected. Failure
to correct this will result in possible injury and damage to the car or property.
We strongly recommend using a failsafe. But remember failsafe does not protect if all power is lost
in vehicle.
•Please confirm the steering and throttle is at neutral position before operating.
4.Check Your Vehicle After Runing
•Turn OFF receiver first, then turn OFF transmitter. This will prevent the car from losing control.
•After running radio controlled car, it is necessary to perform routine maintenance.
5 Safety
IMPORTANT-READ THIS BEFORE RUNNING
•Please be careful when handling the vehicle. It will be hot after running. Pay close attention to
engine and pipe, it is extremely hot.
WARNING: To avoid a possible fire hazard, always unplug the battery. Do not leave your vehicle
unattended.
•On nitro vehicles engine must be shut down first before any radio equipment.

Steering Dual Rates Setup
ST.D/R SW
•DEFINITION:
Steering Dual Rate (ST. DR): Is the adjustment that allows the dual rate value
(maximum servo travel) to be increased (INC) or decreased(DEC) with in a range
of 0% to 100% of the steering servo. This functions very useful in a race
conditions as it allows you to tailor the steering radius and sensitivity for the
current track conditions.
•ADJUSTMENT:
INC
DEC
ST.DR
1.Press and hold the “INC” (Increase) button until the LED on the “ST.DR” blinking green
into a blinking red indicating maximum turning radius or value of 100%.
2.Press and hold the “DEC” (Decrease) button until the LED on the ‘ST.DR” start blinking green
and goes to a blinking red LED indicating minimum turning radius or value 0%.

2. Check your steering on your radio by turning left and right several times.
3. Now turn your steering wheel all the way to the left or right whichever you choose
and hold it while pushing the “DEC” button ( see fig. 1) on the “ST-DR” and
hold it down, you should see that the wheel on your vehicle decrease in radius
(see fig. 2) and that the LED on “ST-DR” will start blinking Green and turn to a
blinking Red indicating it is at 0% or minimal steering radius
.
4. To increase the dual rate turn the wheel left or right all the way and hold it while
pushing the “INC” button this will increase the turning radius of the and the LED
on ST-DR will start blinking Green and turning to the FIRST Blinking Red indicating
that the“Dual Rate” is at 80%, Holding the increase button past the FIRST Blinking
Red will turn to Blinking Green again then to the SECOND Blinking Red indicating
your “Dual Rate” is at 100%. When running your vehicle try to run the “Dual Rate”
at maximum radius (100%). Then if you have too much steering then decease as
needed.
