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.
