Yes. It is normal for the YIKONG YK4082/V3 RC Car to produce a slight gear meshing sound from the Reduction Gear 38T (Part No. 14197) during normal operation. However, if you notice loud abnormal noises, binding, high-pitched squealing, or grinding sounds, you should inspect the reduction gear for worn or damaged teeth, improper gear mesh, or incorrect installation. If necessary, replace any damaged parts promptly to maintain smooth and reliable drivetrain performance.
