Early this year I had my first CC servo failure. Seems there is a plastic part that attaches to the servo that breaks. Had to replace with a used part and 8 months later that one failed. Another used servo, and that one lasted for 4 days. Lucked out and found "the last new one in the country". Hope this will last the rest of MY life. This plastic is evidently deteriorating in the salvage yards, and evidently no one is making a replacement.
