Dan,
Thanks for posting your real-world numbers. Now I know what we will
have to shoot for to beat your hot-rod air racer Piet!
We decided to go with the 76x38 Jay Anderson/Cloudcars scimitar prop
that TN Gene, Jeff and others have spoken highly of. We have our
deposit in on a prop similar to Jeff's, with the dark mahogany stain
and the white tips. Should look pretty sharp.
Thanks again, and have a good day.
Ryan
