Remember it was for a Corvair and is a general statement. "We recently thrust tested a 72" Warp Drive on a Corvair without a cowling, and with a cast iron exhaust and big muffler in place. It pulled 385 pounds of thrust at 2700rpm at a pitch which would yield a cruise speed of 85 or 90mph, with a redline of 105 or 110. With a cowl and a flight exhaust, it would be 425 pounds or so. This combo would produce good average thrust over a wide range of airspeeds. " You can back calculate the pitch at the above link. Not perfect but its at least from people who knows props and direct drive engines.

Orr" Subject: Zenith701801-List: Prop Pitch calculator Here is an Excel spreadsheet (Prop Pitch Speed calculator) I made up from the prop web sites. Use it along with Culver's Prop page and it will get you really close to actual flying numbers. After talking with a few guys flying different props, I put their information in and it comes close to what they are getting in the air. Use it if you want. http://www.culverprops.com/pitchselection.htm Thanks David L.

I've been looking around for one that I could use/borrow. Turns out my son is taking a welding class at a local high school and they have one. Made friends with the teacher and he let me use it. Cost me a dozen donuts. Welcomed me back any time.
