• WARNING: Not suitable for children under 14 years due to small parts. Choking hazard.
• WARNING: Do not ingest any parts.
• Ensure all electrical connections are secure before operation.
• Keep away from water and extreme temperatures.

3. Package Contents

Before starting assembly, please verify that all components are present and undamaged. Refer to the detailed parts list in the official PDF manual for exact quantities.

The set typically includes:

• Various building blocks (beams, pins, gears, etc.)
• 4 Wheels and tires
• 2 Electric Motors
• 1 RC Receiver
• 1 Battery Box (requires batteries, not included)
• 1 Remote Control
• Small screwdriver (may be included)

Important Pre-Assembly Check:

1. Refer to the parts list in the official PDF manual to count and classify all components.
2. Spread out the parts and take photos for your records. This is useful for identifying any missing parts if needed.
3. Ensure all parts are accounted for before proceeding. Contact customer service if any parts are missing.

4. Assembly Instructions

The assembly process involves connecting various building blocks to form the chassis, integrating the electronic components, and attaching the wheels. For detailed, step-by-step visual instructions, please refer to the official user manual PDF: User manual (PDF).

General Assembly Tips:

• Assemble on a flat, stable surface. Avoid soft surfaces like blankets.
• Pay close attention to the orientation and type of each block, especially when dealing with cross axles. The length of cross axles is crucial; for example, a '9-unit' axle refers to its length, not its measurement in centimeters.
• The pre-assembly tutorial on page 2 of the PDF manual is highly recommended for new builders.

4.1. Key Assembly Steps (Summary)

1. Chassis Frame Construction: Begin by assembling the main frame of the chassis using the larger beams and pins.
2. Axle and Suspension Assembly: Construct the front and rear axle assemblies, including any suspension components (e.g., shock absorbers).
3. Gearbox Integration: Install the gears and any gearbox components into the chassis. Ensure gears mesh smoothly.
4. Motor Installation: Securely attach the electric motors to the designated points on the chassis, connecting them to the gear system.
5. Electronic Component Placement: Install the RC receiver and battery box. Ensure they are placed in a way that allows for easy access for battery replacement and wiring.
6. Wiring: Connect the motors, receiver, and battery box according to the wiring diagram. Refer to the remote control manual for specific motor wiring instructions.
7. Wheel Attachment: Attach the wheels to the axles. Ensure any necessary bushings or spacers are used for proper fit.

5. Operating Instructions

Once assembled, your RC car chassis is ready for operation.

1. Battery Installation: Insert the required batteries (not included) into the battery box. Ensure correct polarity.
2. Power On: Turn on the power switch on the battery box.
3. Remote Control Pairing: Follow the instructions in the remote control manual to pair it with the RC receiver on the chassis.
4. Control: Use the remote control to drive the RC car. Familiarize yourself with the controls for forward, backward, left, and right movements.

6. Maintenance

• Battery Replacement: To replace the main control battery, pull out the pin securing the battery box cover (refer to step 118 in the PDF manual for visual guidance). Replace with fresh batteries and secure the cover.
• Cleaning: Use a dry, soft cloth to clean the building blocks and electronic components. Avoid using water or harsh chemicals.
• Storage: Store the assembled model in a cool, dry place away from direct sunlight and dust.
• Check Connections: Periodically check all block connections and wiring to ensure they are secure.

7. Troubleshooting

• Car not moving: Check battery levels in both the car's battery box and the remote control. Ensure all wiring connections are secure. Verify that the remote control is properly paired with the receiver.
• Erratic movement: Check for loose connections or obstructions in the gears. Ensure the remote control is within range and has fresh batteries.
• Parts falling off: Re-examine the assembly steps for any loose or incorrectly placed blocks.

9. User Tips

• Part Identification: When assembling, pay close attention to the length of cross axles. The number (e.g., '9-unit') refers to the number of holes it spans, not a physical measurement in cm or mm. Odd-numbered axles are typically gray, and even-numbered axles are black.
• Battery Compatibility: While the set includes a battery box, batteries are not supplied. Ensure you have the correct type and quantity of batteries for both the car and the remote control before starting.
• Full RC Functionality: The set is designed to be a fully functional RC model, including all necessary components like motors, receiver, and remote control. If you purchased a specific 'set' (e.g., 'set 2 and power'), it should contain all parts for RC conversion.

10. Warranty and Support

For any questions, missing parts, or technical support, please contact the seller directly. Keep your purchase receipt as proof of purchase. The manufacturer, FUN星球 (FUN Planet), also provides design and support for MOC (My Own Creation) projects.
