Excessive use or impact can cause gears to wear out. Replace worn gears and consider using metal gears for durability.

Cooling fins are effective in dissipating heat under normal usage. However, in extreme conditions, consider additional cooling solutions.

This could be due to a disconnected wire, a faulty circuit board, or a burnt-out motor. Check connections and test the motor’s health.

It’s recommended to lubricate the servo gears at least once every 6-12 months, depending on the frequency of use. Using a high-quality silicone or Teflon-based lubricant can help to reduce friction and wear, ensuring that the servo operates smoothly and reliably for extended periods.

Swing arm bushings can wear out over time, leading to increased play and reduced handling precision. To check for wear, inspect the bushings for any signs of tearing, cracking, or excessive play. If any wear is present, it’s a good idea to replace the bushings to restore the RC car’s handling characteristics.
