Setup and Installation

Installing modified parts requires careful attention to detail. The specific steps will vary depending on the part being installed. Always refer to the original MJX RC Hyper Go car manual for detailed disassembly and reassembly instructions relevant to your specific model (14301, 14302, or 14303).

General Installation Guidelines:

• Preparation: Ensure your workspace is clean and well-lit. Gather all necessary tools (e.g., screwdrivers, pliers, hex wrenches).
• Disassembly: Carefully disassemble the relevant section of your RC car to access the part you intend to replace. Keep track of all screws and small components.
• Part Identification: Verify that the new part matches the old part in size and function before installation.
• Installation: Install the new part, ensuring all connections are secure and moving parts operate smoothly. Do not overtighten screws.
• Reassembly: Reassemble the RC car, ensuring all components are correctly placed and secured.
• Testing: After reassembly, perform a basic functional test before full operation.

Specific Part Notes:

• Differential: When installing a new differential (e.g., 16420Y), ensure gears are properly meshed and lubricated. Incorrect installation can lead to premature wear or damage.

• Shock Absorbers: Install shock absorbers (e.g., as seen in Figure 1) with appropriate oil and ensure they move freely without binding. Adjust spring tension as needed for desired suspension performance.
• Tires: Ensure tires are correctly mounted on rims and securely attached to the wheel hubs. Check for proper rotation and balance.
• Suspension Arms: When replacing suspension arms (e.g., 14250), ensure all pivot points are free-moving and secured with pins or screws.

• Pinion Gear: When replacing the pinion gear (e.g., 14392), ensure proper gear mesh with the main spur gear to prevent stripping.

Operating Your RC Car with New Parts

After installing new parts, it is crucial to perform initial tests before full-speed operation to ensure everything functions correctly and safely.

1. Initial Power-Up: Connect the battery and power on your RC car and transmitter. Check for any unusual sounds or movements.
2. Steering Check: Test the steering by turning the wheels left and right. Ensure full range of motion and that the wheels return to center.
3. Throttle Check: Slowly apply throttle to ensure the motor spins correctly and the car moves forward and backward as expected. Listen for any grinding or binding noises from the drivetrain.
4. Suspension Check: Gently press down on the car to compress the suspension. Ensure the shock absorbers rebound smoothly and evenly.
5. Low-Speed Run: Conduct a low-speed test run in an open area to observe overall performance and stability.
6. High-Speed Run (Optional): If all low-speed tests are satisfactory, gradually increase speed, paying attention to handling and any new sounds.

New parts may alter the car's handling characteristics. Take time to get accustomed to any changes in performance.

Maintenance

Regular maintenance of your RC car parts will extend their lifespan and ensure optimal performance.

• Cleaning: After each use, especially in dirty or dusty conditions, clean the parts to remove debris. Nylon parts can be wiped clean with a damp cloth.
• Inspection: Periodically inspect all modified parts for signs of wear, cracks, or damage. Pay close attention to gears, suspension components, and drive shafts.
• Lubrication: Apply appropriate RC-specific grease or oil to moving metal parts, such as differential gears and universal joints, to reduce friction and wear. Avoid over-lubrication, which can attract dirt.
• Fastener Check: Regularly check all screws and fasteners for tightness. Vibrations during operation can cause them to loosen.
• Shock Absorber Maintenance: Check shock oil levels and replace if necessary. Inspect O-rings for leaks.
• Tire Care: Inspect tires for punctures, tears, or excessive wear. Clean dirt from tire treads for better traction.

Troubleshooting

If you encounter issues after installing new parts, consider the following common troubleshooting steps:

• Car not moving or moving erratically:
  • Check all electrical connections (battery, ESC, motor, receiver).
  • Ensure gears are properly meshed and not stripped.
  • Verify that drive shafts are correctly installed and not binding.
• Unusual noises (grinding, clicking):
  • Inspect differential and other gear assemblies for foreign objects or damage.
  • Check for loose screws or parts rubbing against each other.
• Poor handling or uneven suspension:
  • Ensure shock absorbers are installed correctly and have sufficient oil.
  • Check suspension arms and steering components for binding or damage.
  • Verify tires are securely mounted and not damaged.
• Part feels loose or falls off:
  • Re-check all fasteners and ensure they are tightened appropriately.
  • Confirm that the correct size and type of screws/pins were used during installation.

If problems persist, consult the original RC car manual or seek assistance from experienced RC enthusiasts or a professional repair service.

User Tips

• Check Hardware: Before starting any installation, ensure you have all necessary screws, pins, and small hardware components. Missing hardware can halt your project.
• Body Shell Compatibility: If you are looking for specific body shells, such as a "Mini body," verify its compatibility with your MJX RC Hyper Go chassis before purchase.
• Organize Parts: When disassembling your RC car, use small containers or a magnetic mat to keep track of different screws and parts to simplify reassembly.
• Reference Manuals: Always keep your original RC car's instruction manual handy for reference during part replacement.
