2.2 Vehicle Battery Installation and Charging
- Carefully remove the RC car body shell to access the battery compartment.
- Connect the provided LiPo battery to the vehicle's power connector.
- Secure the battery within its compartment.
- To charge the battery, disconnect it from the RC car. Use the provided charger (10V-800mA EU regulation charger for A959-B) to charge the 7.4V balanced battery separately.
- Important: When the battery runs out, charge it promptly. Do not allow the battery to become completely empty, as this may prevent it from charging. Always disconnect the battery from the car during charging.

2.3 Initial Pairing
- Ensure both the RC car and the remote controller are powered off.
- Turn on the RC car.
- Turn on the remote controller. The controller and car should automatically pair. A successful connection is usually indicated by a solid light on the controller.
- Perform a short test of steering and throttle to confirm functionality.
3. Operation
3.1 Basic Controls
- Steering Wheel: Rotate left or right to control the vehicle's direction.
- Throttle Trigger: Pull to accelerate forward, push to brake or reverse.
- Trim Adjustments: Use the fine-tune knobs on the remote controller to adjust steering and throttle trim for straight driving and neutral throttle.
3.2 Driving Tips
- The 1:18 scale allows for both indoor and outdoor control.
- The 2.4GHz radio system supports multiple RC cars operating simultaneously without interference, up to a range of approximately 100 meters.
- The car is suitable for various terrains including flat ground, gravel, and grassland due to its all-terrain rubber tires and four-wheel shock absorbers.
- The full simulation structure provides real car control feelings, including high-speed driving, instant acceleration, deceleration, braking, backing, turning, and lights.
- Independent suspension of front and rear wheels ensures smooth cornering and stable body posture.
- The vehicle features a differential for improved turning and stability.

4. Maintenance
- Cleaning: After use, especially in dusty or wet conditions, clean the car to remove dirt and debris. Use a soft brush or compressed air for hard-to-reach areas.
- Battery Care: Always charge the battery as soon as it runs low. Store batteries in a cool, dry place. Do not overcharge or completely discharge LiPo batteries.
- Motor and ESC: Regularly check the motor and Electronic Speed Controller (ESC) for excessive heat during operation. Ensure proper ventilation.
- Tires: Inspect rubber tires for wear and tear. All-terrain rubber tires provide strong ground adhesion and friction resistance.
- Shock Absorbers: The four-wheel shock absorbers help adapt to various terrains. Check them for proper function and any leaks.
- Bearings: Bearings are crucial for supporting rotating parts and reducing friction. Ensure they are clean and lubricated if necessary.
- Differential: The differential aids in smooth turning. Inspect for any unusual noises or resistance.
