Carbon Fiber (and Owen Bell) To The Rescue

Owen makes the ring (P/N 1552127-2), which is common to all 337 Skymasters and is where the cracks typically appear. I don't know that he makes the rest of the rear panel.

I highly recommend a dynamic prop balance. Without it, vibs will always be a factor.
