I hate to tell you guys 'I told you so, but...'.  An't the 2.85 ratio great!  Congradulations Tracy on your results so far.  I have also been preaching the benefits of peripheral ports, but to no avail.  And since it doesn't look like I am going to get an airplane built anytime soon, it looks like someone else will have to prove the superiority of the PP.  Of course, the Renesis will probably prove superior to the PP so this may not matter.  Tracy, 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.
