Buly,
I have the program (actually 2 programs) on my computer at work.  What redrive ratio and how much HP?
I'll check it out tommorrow.

BTW my prop program (written by the guy that did the RV-9 wing, I can't seem to remember
his name at the moment) calculated a 91 pitch for a 72" diameter. Close to
yours but I realize that there alot of other factors as well.

Ken, I need somebody to figure out the templates for my prop. Do you think
you can do it with your program? Few others struck out. They could not
handle the numbers for the turbo Cosmo 13B.
