Leester, great looking plane. The Fox will be a great engine for it. I disagree about pitch being the cure for most set ups. I myself am running a B-25 on the Brodak Mauler that you seen Emmy flying at Tulsa lasy year. I was reprimanded for not setting needle right first round. It flies best with a Power Point 10-4 prop. In calm weather, which we have little of, I run a 10-5. I have been told that diameter and low pitch is for pulling power. Small diameter and high pitch for speed. Anyway when you get the Fox working, you might try the B-25 again. Later, DOC Hollliday
