On that note, Tracy (or anyone). Do you think the use of the Sam James rotary cowl would make a difference with regards to the IVO prop? I recall you had some problems with flow around the root of the prop. I was considering this prop until I read your findings.

Best I could measure, the stock dimension is 37.5" Mine is close to 40" due to the extra length of the 20B. I simply glassed a round collar extension behind the prop spinner to get the extra length. I think this improved the looks and getting the prop further away from the cowl is aerodynamically better.
