Yes, its the ones that butt against the shaft that made the scars. It didnt make a scrape around the shaft it just made two tiny craters where they had been. I guess they were on too tight. It wasnt on the inner shaft thankgoodness. I just sanded the little scars out so I dont have to worry about that anymore but it made it difficult to put the aluminum swashplate on. I dont really like the aluminum swashplate though so I took it off. If I need it I have it but I dont realy think it helps.
