Craig will want you to order a 7" dia extension with 7/16" prop bolts from www.sabermfg.com.

If you order the three-blade, it will be smoother and look sexy, but your glide ratio will suffer if you care about that.

Kismet, are you out of the woods and in your way home?

I would consider replacing the prop. If it failed in flight the outcome is likely to be fatal.

Oh, would you "safer than thou" guys just stop it? The ugly parts of my Great American prop are just cosmetic, not structural and the Great American props used micro-laminations rather then just three or four as in the OPs case - a much more sound way of building a prop. I've flown across the Country with this prop and even (accidentally) had it up to 3,000 RPM not long ago. If the prop were going to fail, it would have done so then. My engine didn't fly apart either. Not all of us can afford to shell out $2,500 for a new prop every time we see a minor, cosmetic defect.

Alright boys and girls,

Flew the pacesetter without a spinner today (no backplate). Honestly, I think it's almost the same speed with the little "test pilot" wind triangle I did. Regardless, climbs amazingly and ran smooth enough by just leaving my existing dynamic balancing washers where they were.

Not bad.

I am going by your statement that your prop is the worse than the OP?s which is not just cosmetic.

Watch the CHT's in case the absence of a spinner disrupts airflow into the cowl.

I agree; Pacesetter made really good props. And if performance is similar to your previous prop, that's a real bonus; it's rare to get a good match when you're forced by circumstance to take whatever is available.

I wonder why so many propeller manufacturers have gone out of business. Great American, Aymar-Demuth, Pacesetter...
