Maintenance

Regular maintenance ensures the longevity and performance of your RX12 rally car.

• Cleaning: After each use, especially on dusty or dirty terrain, clean the car with a soft brush or compressed air to remove debris. Avoid using water directly on electronic components.
• Tire Inspection: Check tires for wear, tears, or punctures. Ensure they are securely mounted.
• Suspension: Inspect the metal large diameter long stroke hydraulic dampers for leaks or damage. Ensure smooth operation.
• Gears and Drivetrain: Periodically check the 2W silicone damping planetary gear differential and 59T CNC high carbon steel deceleration gear for debris or signs of wear.
• Battery Care: Store batteries in a cool, dry place. Do not leave batteries fully charged or fully discharged for extended periods.
• Motor: The Rocket 2845 brushless motor is designed for durability, but ensure it remains free of obstructions.
