Your car is equipped with the new 2.4GHz radio system. Please read and understand all
instructions below before operating.
Steering Wheel: Proportionally operates the models right and left steering control.
Battery Case: Requires 3pcs of AA size batteries.
Power Switch: Used to turn the radio controller ON/OFF
Steering Dual Rate Dial: Allows you to change the amount of steering servo travel compared
to the amount of physical movement of the steering wheel.
Throttle /Steering Trims: Used to adjust the center trim of the throttle/steering channel.
Steering Reverse: Allows you to electronically switch the direction of steering servo travel.
For example, if you move the steering wheel to the right and the steering servo moves to the
left, flip the Steering Reverse Switch to make the steering servo move to the left.
Throttle Reverse : Allows you to electronically switch the direction that the motor operates
in relation to the throttle trigger. For example, if you pull the throttle trigger to accelerate
forward, but the model goes in reverse,
flip the Throttle Reverse Switch to make the model accelerate forward.
Trigger: Controls the speed and braking ability of your car. Pull it to accelerate, release it to
decelerate, and push it to brake. Pushing it a second time activates the reverse feature.
Indicators: Shows battery power level. Green indicator flashing means battery power is low.
If both red and green indicators are flashing then the radio controller battery is too low to
control the model and you must replace with fresh batteries immediately.
Bind(Pair) button: It is used to bind your 2.4GHz radio system.
1) Slide the battery cover as shown and install 3pcs of
AA size batteries, positioning the polarity as indicated.
2) Replace the battery cover after batteries are installed.
-Use batteries of same type.
-Remove batteries from the case if not in use.
-Always check the battery power.
-Dispose of exhausted batteries properly.

CAUTION
TO BIND THE RECEIVER TO THE RADIO CONTROLLER
Power Switch
Before running, make sure that the radio controller is bound with the receiver, which has been
done at factory. If the model is not responding to the controller, it is possible that the controller
and receiver are not bound, and you must perform the binding procedure following the
instructions below.
1)Turn on the receiver (3-in-1 unit) using the
power switch located on the side of the car.
(Note: Receiver and ESC are combined inside
the 3-in-1 unit.)
2) Hold the Bind(Pair) key and switch
on the power on the controller.
You must Hold the Bind(Pair) within
5 seconds of turning on the receiver.
3) The green indicator should flash, meaning
that the binding process is being performed.
4) Once both red and green indicator
are lit and not flashing, then your
receiver is bound to your radio
controller. The binding process is
complete.
Before using your car, make sure the radio controller has sufficient battery power.
If the battery power is too low it can lead to the loss of control of your car.
Always turn on the remote controller FIRST, and then the receiver.
