After 75 hours with the aluminum back plate, I had developed numerous stress corrosion cracks, eventhough my spinner was supported at the prop dome. A few were large, but most were not visible until I put the back plate under a macroscope. The carbon backplate has been trouble free for the last 225 hours.
