Regularly checking on the transmitter (radio controller) power is very important. Remove the batteries from the transmitter (radio controller) when not in use. Replace with fresh batteries if necessary. NEVER run this vehicle with low power from the transmitter.
When this vehicle becomes stuck, do NOT force on throttle. Failure to do so could cause abrupt damage to the motor and/or the ESC (Electronic Speed Controller). Check and clean the obstacles before running again.
Before running this vehicle check if the battery, wiring, and plugs are loose.
Be careful not to touch any moving parts when servicing or operating this vehicle.
To prevent excessive RPM from damaging the motor, and/or the drive-train components, we suggest reducing the throttle while performing in the air during jumps.
Never attempt to re-assemble motor, ESC, and receiver as these have been precisely calibrated at factory.
Always apply the factory optional/tooling parts to this vehicle.
To upgrade this vehicle requires the user to upgrade the entire radio/driving system (such as motor, ESC, receiver and so forth.) They should be strictly matched with factory components.
To run this vehicle, turn on the transmitter (radio controller) first and then the receiver.
To stop running this vehicle, turn off the receiver first, and then the transmitter.
Straighten the receiver antenna (if it comes with this vehicle) for best receiving performance. Never cut the receiver antenna, otherwise it could lose control of the vehicle.

Practice Required:

Beginners should start slowly. Keep practicing until you feel comfortable with steering, throttle, and brakes. Once you feel comfortable driving the vehicle try a different terrain and speed until you have mastered the basics.

Slide and remove the battery cover from the transmitter, install two AA size batteries (1.5V,each), and replace the battery cover. Do not reverse the polarities when installing. Always use batteries of same brand and remove batteries when not in use. Make sure battery power is sufficient before use.
Please replace the batteries for the transmitter ii the transmitter LED blinks slowly.

Starting Driving:

Switch on the Transmitter:
Slide the Power Switch to “ON” position. Make sure the transmitter has enough battery power. Please replace with the new batteries for transmitter if the LED on transmitter blinks slowly. Do NOT move the trigger and the steering wheel while the transmitter is waiting for binding.
Switch on the ESC/Receiver:
Press and hold the Power Switch on ESC/Receiver for 2-3 seconds to turn on the car. It will take a few seconds before LEDs (on Transmitter and the ESC/Receiver) stop blinking and become solid on, which indicates that the car is bound with the transmitter. Binding operation may fail with low battery power. Please stop and charge the battery pack once the car jerks, cogs, or moves slowly. Under the circumstance of flat battery power, the car may have steering but not throttle. In case the car runs harshly or noisily, stop to check if there is something clogged in the drive train.
Checking the steering performance by turning the steering wheel: A) With the steering wheel centered, the vehicle runs in a straight line.
Slight adjustment by flipping the steering wheel is occasionally needed. It largely depends on the terrains that you drive.
B) Turn the steering wheel to the left, and the car turns left.
C) Turn the steering wheel to the right, and the car turns right.
Throttle Control: Pull the trigger to accelerate, release it to slow the speed, and push to brake. Pull it to the Center Position and push it again to go reverse.
Steering Trim Knob: It is used to set the steering neutral point on front wheels. If the front wheels on the vehicle veer in one direction while the steering wheel is centered, turn this knob in the opposite direction until the vehicle drives straight.
Speed Switch Knob: The Speed Switch is actually the throttle limiter. Turning down the knob all the way will reduce the maximum speed down to 40% of maximum speed. Turning up the knob will increase max speed up to 100%. It is advisable to operate the vehicle on the slower setting until you have had enough practice before operating at higher speeds.
Steering Direction Reverse Switch: If the vehicle turns right when you steer left, flip “Steering Reverse” switch. If the vehicle turns left when you steer right, flip “Steering Reverse” switch.

Stopping Driving:

Press and hold the POWER switch for 2-3 seconds on vehicle to switch off the power.
Switch the Power switch on transmitter to OFF position to switch off the transmitter.
Disconnect and remove the battery pack from vehicle if not in use.

Headlight Installation:

The headlight LEO is gifted as an optional part in the box. NUOKE 903
