Every time I try that link it says "connection refused".

I don't know what they say but if it's other than the following I'd
have some serious doubts.

More blades mean shorter blades for a given HP rating.
Shorter blades means less noise.
Bos with 2 blade props are noisy! Tips are supersonic.
More blades also raises the frequency of the noise and that lowers the
apparent noise level.
More blades are less efficient. in cruise, but better climb.
More blades mean less vibration, but they have to be suited to the
harmonics of the engine and engine balance weights.

Works for me...here's what they say:
(Understand, though, that the Q-Tip propellers are quite good at cruise as
well as TO and climb)

----------------------------------------------------------------------------

New Continental IO-550B 300 horsepower -- for more speed, better climb
and reliability.

New Hartzell 4-blade "Q-Tip" propellers with Woodward governor for an
extremely quiet, vibration-free ride.

Shadin Digiflow fuel computer -- for extremely precise fuel management.

All new accessories, hoses and belts -- for hours of trouble free
service.

Only 10 working days downtime


Compared to a stock Bonanza the Colemill STARFIRE modification gives you...

Shorter takeoff roll

Increase rate of climb

Faster cruising speeds

Much quieter cabin

Distinctive new look

Would that be a kick in the ass when hooked to a Turbo Normalizer.
