4. Setup Guide

4.1 Remote Control Battery Assembly

The remote control requires 4 x 1.5V AA alkaline batteries (not included).

1. Slide and remove the battery cover located on the bottom of the remote control.
2. Insert the batteries according to the specified polarity direction (+/-) indicated inside the battery compartment.
3. Close the battery compartment securely.

Caution:

• Never mix different types of batteries (e.g., alkaline with rechargeable).
• Never mix old and new batteries.
• Remove exhausted batteries promptly.
• Always keep batteries out of reach of children.

4.2 Charging the Vehicle Battery

The vehicle uses an 11.1V 2200mAh Lithium Battery. Use the supplied USB charging cable and an optional balanced fast charging case.

1. Ensure the vehicle is switched off and the battery is removed from the model before charging.
2. Connect the Type-C charging cable to a power adapter (not supplied) and then to the input port of the balanced charging box. The red light on the charging box will turn on.
3. Connect the vehicle's battery to the charging box. The green light will start to change gradually, indicating charging in progress. If the charging box supports high-current series charging, the red light will flash quickly; otherwise, it will remain steady.
4. Charging is complete when both the red and green lights are on. The green light will go out when the battery is removed.

Battery Safety Precautions:

• Do not charge the battery if it is bulging or swollen.
• Keep the battery away from humidity, corrosive environments, and heat sources.
• Rechargeable batteries should always be charged under adult supervision.
• Do not short-circuit, disassemble, or put the battery into fire.
• Discarded lithium batteries should be disposed of responsibly. Contact your local environmental authority or a recycling center.

4.3 Receiver Connection

The receiver connects to the ESC, servo, and lights. Ensure all connections are secure.

ESC Function Diagram:

Note: Use the 3-pin setting interface marked on the ESC to connect the setting card, not the throttle cable. The setting card supports multiple ESCs, so refer to the ESC manual's parameter table for accurate settings.

4.4 Initial Power-on Sequence

1. Turn on the remote control power switch. The R.LED light will illuminate.
2. Turn on the power switch of the vehicle. The ESC will beep three times, indicating the vehicle connection is complete.
3. You can now begin controlling the vehicle.

Important Power-on/Power-off Sequence:

• When starting up, always turn on the remote control first, then the vehicle.
• When shutting down, always turn off the vehicle first, then the remote control.
• Ensure only one remote controller and high-speed vehicle are paired at a time to avoid interference.

5. Operation

5.1 Pre-operation Checks

• Read the instructions thoroughly.
• Ensure all screws and nuts are properly tightened.
• Use fully charged batteries for both the remote control and the vehicle to prevent loss of control.
• Make sure the throttle trigger on the remote control is in the center position before powering on.

5.2 Remote Control Function Overview

5.3 Control Method

Familiarize yourself with the control inputs:

• Steering: Turn the steering wheel left or right to control the vehicle's direction.
• Acceleration/Brake/Reverse: Push the throttle trigger forward for acceleration. Pull it back slightly for low speed, or fully back for braking and then reverse.
• Fine-tuning: Use the ST.TRIM and TH.TRIM buttons to adjust steering and throttle trim if the vehicle doesn't drive straight or stop correctly.
• Rudder Adjustment (ST.D/R): Adjusts the steering angle of the front wheels.
• Direction Reversal (ST.REV): Changes the direction of the vehicle's steering.
• Throttle Inversion (TH.REV): Changes the forward and reverse direction of the vehicle.

5.4 Driving Tips

• Practice driving in an open, unoccupied area (wider than 8x8 square meters) to avoid accidents.
• Start by practicing driving in a circular track, then move to figure-8 patterns to improve control.
• Always start the vehicle at a low speed to prevent skidding or loss of control.
• Avoid operating the vehicle at its highest speed, especially indoors or on smooth surfaces, to prevent injury or damage.
• Do not operate in public streets or crowded places.

6. Maintenance

6.1 General Maintenance

• When not in use, remove the batteries from both the vehicle and the remote controller.
• Completely remove mud and dirt from the vehicle before storing it.
• Oil the external leaky wheel cups and metal parts regularly.
• Store the vehicle and battery separately when not in use.

6.2 Motor Care

• For the first use of a rechargeable battery, operate the vehicle steadily on a flat road surface to properly seat the motor brushes. Failure to do so can reduce motor performance and service life.
• Preventing overheating is crucial for prolonging motor life. Frequent turning, starting/stopping, pushing objects, and operating in deep water or long grass can lead to excessive wear and tear.

8. Assembly Diagrams

The following diagrams illustrate the various assemblies and components of your ZWN RC car. These are useful for maintenance, repairs, or part replacement.

9. User Tips

• Initial Check: Before every run, quickly check all major connections and ensure the battery is fully charged for both the car and the remote.
• Terrain Adaptability: Your ZWN RC car is designed for various terrains. Start on flatter, open ground to get a feel for the controls before tackling more challenging environments like sand, grass, or mud.
• Gradual Speed Increase: The brushless motor offers high speed. Always start at a lower speed and gradually increase as you become more comfortable with the controls to maintain stability and prevent rollovers.
• Night Driving: Utilize the high-brightness LED headlights for extended fun during dusk or night, ensuring visibility.
• Post-Run Cleaning: Especially after off-road use, clean any dirt or debris from the chassis, wheels, and moving parts to ensure longevity and smooth operation.
