5. Maintenance

Regular maintenance will ensure the longevity and optimal performance of your TAMIYA Hornet EVO.

• Cleaning: After each use, especially in dusty or dirty conditions, clean the chassis and body. Use a soft brush or compressed air to remove debris from moving parts.

• Gearbox and Drivetrain: Inspect the DT-02 based rear transmission for any signs of wear or damage. The kit includes ball bearings, which require less maintenance than bushings but should still be checked for smooth rotation.
• Tires: Check tires for wear and tear. Replace if significantly damaged or worn to maintain traction.
• Electronics: Ensure all wiring connections are secure and free from damage. Keep the motor and ESC free from excessive dirt.

6. Troubleshooting

This section addresses common issues you might encounter with your RC Hornet EVO.

• Gear Mesh: Ensure the motor pinion gear and spur gear have proper mesh.
• Drivetrain Obstructions: Check for any debris or foreign objects obstructing the wheels or drivetrain components.
• Rear Axles: Some users have reported issues with rear axles on similar models. If experiencing consistent issues with the rear wheels or drivetrain, inspect the axles for wear or damage. Aftermarket axles may be an option for enhanced durability.
