There has been some interest. The BASICALLY NEW Whirlwind 74HRT is still available. I asked WhirlWind to delay finnishing the propeller for a week to allow a buyer to choose their color. New price.

Regards,

Thumbs up 74 HRT

I switched my high-compression AV IO-360-powered RV-8 from the Whirlwind 200RV prop to the 74HRT last fall. The 200RV has a small blade area, narrow tip planform while the 74HRT has much more blade area in a "scimitar"-ish planform.
My primary reason for switching was to get more responsiveness when flying formation. This was definitely achieved! In addition, solo takeoff (WOT acceleration, flat pitch) and rapid descent (closed throttle, flat pitch) are both noticeably improved.
I was expecting a small hit in cruise efficiency, but that did not occur.
I attribute that to the different twist distribution and very thin blades on the 74HRT.
On top of all that, the prop is very sexy! I'm sure I look 10 years younger on the ramp now! Overall I give it 3 thumps up!

Boy, I rubbed this prop more than once when nobody was looking, thinking if I wasn't already committed to a prop plan on my -8 project...
