Bryan,

The prop is on its way, via USPS parcel post. No actual tracking #, but ins. # is: VH-671-844-681-US.

Enjoy....

I took the calipers to my dyno-prop today. After the glass and micro, I have a cross section of 88mm all around. With my 3.18 gear reduction, it will only absorb 123Hp at 7000 RPM, according to the spreadsheet. 
 
The second page suggests having several bars. This one wasn't to hard to make, so I guess making a few more will be in my future. I need to get out to 100mm before I'll have a bar that the spreadsheet says will absorb over 180Hp. 
 
Brian, I'll be cutting this bar down to 52" (1320mm) tomorrow or Sunday. With a 2.85 reduction, 6500RPM will require 137Hp to spin the bar at 2281.

Brian,

I've got a couple of cut-down props that were originally intended for 160 hp Lyc. RH rotation, 3/8" bolts, should fit Tracy's C gearbox. They were originally good for around 2200 rpm static; they'd be significantly higher now since they were cut down a lot.

If you want to use one, just let me know where to ship it.

Charlie
