HPI RS4 Sport 3 Flux Questions
#1
Hey everyone, I recently got a HPI RS4 Sport 3 Flux and I have a few questions.  Whenever I go at the slowest speed, I can hear the differentials or gears grinding.  Is this normal?  It was like that out of the box.  When I was adjusting a coilover, I unscrewed the top and oil got on the coilover.  What should I do?  I tightened it and it doesn't feel softer. If I run it on snowy or salty roads, what else do I need to take care of it and how should I do that?  Thank you.

Are you sure the diff gears are grinding? Are you sure it's not the motor cogging? Check the mesh of the pinion and spur gears.

Just make sure to clean the chassis with compressed air and re-oil and grease moving parts that require lube.

No, I'm not sure it's the gears. What's the cogging of the motor? Thank you, I'll try that.

Motors cog sometimes at very, very low rpm because of the magnets and poles lining up within the motor and wanting to stay there, kind of, because there isn't enough momentum to overcome the magnetic attraction. I think I'm explaining that right. Either way, it's normal in some motors and isn't really harmful.
