Manutenzjoni
1. Tindif Ġenerali
After each use, especially in dirty or wet conditions, clean the vehicle thoroughly. Use a soft brush or compressed air to remove dirt and debris. Avoid using harsh chemicals that could damage plastic or electronic components.
2. Screw and Fastener Checks
Regularly check all screws and fasteners for tightness. Apply blue threadlocker to metal-to-metal screws as needed, especially on critical components like wheel hubs and suspension mounts, to prevent them from loosening during operation.
3. Shock Oil Inspection

Immaġni: Dettaljata view of the vehicle's shock absorbers and suspension components.
Inspect the shock absorbers for leaks or inconsistent damping. Over time, shock oil can degrade or leak, affecting suspension performance. Replace shock oil as necessary, referring to the full manual for recommended weights (e.g., 35wt for stock, adjust for driving style).
4. Pinion/Spur Gear Inspection
Periodically check the pinion and spur gears for wear or damage. Ensure proper gear mesh to prevent premature wear. If changing to a 3S battery, consider adjusting the pinion gear size to manage motor temperatures and prevent damage.

Kwistjonijiet Komuni u Soluzzjonijiet
- Il-vettura ma tirrispondix: Ensure transmitter and vehicle batteries are charged and properly connected. Check for proper binding between transmitter and receiver.
- Is-sħana żejda tal-mutur: Verify correct gearing for your battery type (especially 3S LiPo). Ensure adequate airflow to the motor and ESC. Reduce run time or consider a smaller pinion gear.
- Stripped screws: Use high-quality hex drivers for maintenance. For small set screws, apply threadlocker carefully and allow it to cure before attempting to loosen. If a screw is stripped, specialized extraction tools may be required.
- Poor handling/suspension: Inspect shocks for leaks or damage. Check suspension arms and linkages for binding or broken parts. Adjust shock oil weight or spring tension as needed for terrain.
