3.3 Installing the Car Battery
- Remove the car body shell by detaching the body clips.
- Locate the battery compartment on the chassis.
- Carefully insert the charged battery into the compartment.
- Connect the battery connector to the car's ESC (Electronic Speed Controller) connector. Ensure a secure connection.

4. Operating Instructions
4.1 Powering On and Pairing
- Turn on the remote controller first. The power LED should illuminate.
- Turn on the RC car by pressing its power switch.
- The car and remote should automatically pair. If not, turn both off and repeat the process.
4.2 Basic Controls
- Throttle Trigger: Pull the trigger to move forward, push it to brake or reverse.
- Steering Regulating Wheel: Turn the wheel left or right to steer the car.
- ST. TRIM: Adjusts the steering trim to ensure the car drives straight when the steering wheel is centered.
- TH. D/R (Throttle Dual Rate): Adjusts the maximum throttle output. Lowering this can make the car easier to control for beginners.
The 2.4GHz radio system provides a control distance of up to 120 meters and anti-jamming capability, allowing multiple cars to race simultaneously.
4.3 Driving Tips and Terrain Adaptability
This RC car is designed to conquer various terrains, including beaches, snow, grass, mountain roads, and rock roads, thanks to its hardware oil shock absorbers and metal chassis.
- Start in an open area free from obstacles and people.
- Begin with slow speeds to get accustomed to the controls before attempting high-speed maneuvers.
- Avoid driving in deep water or extremely muddy conditions to prevent damage to electronic components.
- Be mindful of battery life; performance will decrease as the battery drains.

5. Maintenance
Regular maintenance will extend the life and performance of your RC car.
- Cleaning: After each use, especially in dusty or sandy conditions, clean the car with a soft brush or compressed air to remove dirt and debris from moving parts, motor, and chassis.
- Battery Care: Store batteries in a cool, dry place. Do not store fully charged or completely depleted for long periods. For long-term storage, charge to approximately 50%.
- Component Inspection: Regularly check screws, nuts, and linkages for looseness. Tighten as necessary. Inspect the shock absorbers for leaks and the tires for wear.
- Motor and ESC: Ensure the brushless motor and ESC (Electronic Speed Controller) are free from obstructions and have adequate ventilation.
