Being the newbie that I am, I figured I’d take a pic and ask here. I’m seeing what looks like a bunch of oil/grease on this part of the drive shaft going into the center diff as well as on this end of the chassis brace. This is on the Karton 6S V5. I’ve run it a total of three times with nothing heavy at all so I’m thinking it was like this out of the box. Any suggestions?
