Baffle cracks with composite prop

On that lengthy SB thread Vic Syracuse mentions an apparent lack of baffle cracking on aircraft with composite props.
I got major cracks in the usual place after only 11 hours!

WW200RV prop - composite
Inboard edge of the oil cooler was braced to the case centre line.
Baffle kit was one of the newer "improved" versions.

I must be unlucky.

I've had a few cracks appear on my baffles over the years. Nothing outrageous, or difficult to repair. There's a lot of thrashing about that goes on in there...

I was referring to the baffling, and not the oil cooler mounts. They appear to have their own set of issues.

Exact same story here Jim!

First showed up at about 30 hrs and became terminal at about 70 hrs. I also have the WW 200RV and new style baffles.
