Jim,

I think you're WAY off mark here. When you're bored one day, try throwing

things at a you're ceiling fan. Sometimes you'll be lucky sometimes you

won't.

 

When something comes off an engine and hits a prop (ANY prop) there are lots

of variables at work which determine the damage that's going to be caused.

The item involved, the RPM at the time, the exact impact angle and position

of the prop at the second the item hits it, and pure dumb luck come to mind

as just a few.

 

No offense to Craig Catto and his excellent products, but I'd suggest that

the latter is the main reason for the end results in both you're case and

Dave Domier's.

Regards,

John

 

I don’t disagree with what you’re saying, John; but I don’t have to look at the construction of Catto’s prop vs Performance very long to conclude that those glass wraps are going to make it a much “tougher” prop than the Performance.
