2.4GHz Transmitter Introduction:

1. Steering Wheel
2. Trigger
3. Steering Trim
4. Speed Selection
5. Steering Direction Reverse Switch
6. Power Indicator
7. Power ON/OFF
8. AUX. Button (This button is disabled for this car)

Brushed ESC/Receiver:

Always straighten the antenna for the best performance.

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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:

1. Press and hold the POWER switch for 2-3 seconds on vehicle to switch off the power.
2. Switch the Power switch on transmitter to OFF position to switch off the transmitter.
3. 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.

1. Insert the lights into the slot on the back of the front bumper as shown in the photo.
2. Lay and secure the wires on the chassis as shown in the photo.
3. Insert the plug into the LED slot as shown in the photo.

Charging The Battery Pack:

Troubleshooting:

A.The vehicle does not work at all:

1. Check to ensure that radio controller and car are switched on.
2. Check if there are damaged parts/wires/connectors, repair or replace if necessary.
3. Car battery is flat. Charge the battery pack.

B. The vehicle runs slowly:

1. Car battery is flat. Charge the battery pack.
2. Check if the vehicle is properly geared and no dirty or stripped gears are found. Make sure there is a reliable gear mesh for motor pinion and the spur gear.
3. Check if there is something stopping the moving parts and clean them immediately.

C. The throttle works but not the steering:

1. Check if the servo feels jammed, and try centering it gently if it is the case.
2. Check if the servo link is loose or the servo breaks. Repair or replace if needed.

D. It steers, but throttle is uncontrollable:

1. Check if there are damaged parts in the overall drive train.
2. Check the battery power both for radio controller and the car.

E. The vehicle runs noisily:

1. Check gear mesh between spur gear and motor pinion.
2. Check if there are stripped and/or dirty gears.
3. Check if there are some parts getting damaged in the overall drive train.

F. The vehicle is found one direction’s steering travel is not same to the other.
Please tune the Steering Trim until Steering Center Point is fixed.
G. Not able to charge the batteries:
Check if either the charger or the batteries is damaged, or batteries are over-discharged.
