CC are chinese made motors made by third parties with no direct control of the quality of materials. These can change, or a bad batch can go through these factories without the knowledge of the QC. (Just saying is all)
That is true but Castle does own the factory but being a million miles away can be a problem from time to time. I know Castle has guys going to the factory every so often.
