This is likely due to overheating or low-voltage protection kicking in.
Let the ESC cool down, and check the battery voltage.
If the battery is old, replace it. Ensure the ESC’s airflow isn’t blocked.
Grinding usually means worn gears or lack of lubrication.
Open the diff, inspect the gears for chips/damage, and replace if needed.
Apply high-quality silicone diff grease to reduce friction.
This can be caused by low battery voltage in the remote, signal interference (e.g., from Wi-Fi routers or other RC cars), or a faulty receiver antenna.
Replace remote batteries, avoid crowded frequencies, and ensure the car’s receiver antenna is fully extended.
Uneven wear is often caused by aggressive driving (e.g., constant drifting or hard braking) or mismatched tire hardness for the surface.
For example, soft tires grip better on dirt but wear fast on pavement. Replace tires with ones suited to your terrain (soft for dirt, hard for asphalt).
