Insteresting Metalic Grinding Sound from Engine or Clutch of Hpi RS4

[SametRS4]

Hi all, I hope you are well. I heard this sound when I run the engine 3 days ago. When I checked the clutch shoe, it was completely worn and there was a trace of the spring on the clutch bell. I changed the clutch shoe but the sound did not stop. The engine runs easily and the vehicle accelerates very well, but this sound worries me.

Could be the rear bearing going bad, that's been described as having a "gravelly" sound.

Since I heard this sound, the flywheel does not turn clockwise (when I look at the vehicle from the front). Could rear bearing have an effect with this situation?

They have a one way bearing.
