Well, I have taken the boat about as far as I can before I set the center spars. My problem is this; I have cut 2 inner wing ribs from 3/32 plywood using the original plans I bought in 1986 (the plans supplement I bought late last year did not include a full size inboard rib template, only the outer ribs, so I used the only full size template I had). When positioned on the fuselage sides over the spar holes, the chord lines on the ribs show exactly 3.5 degrees positive incidence (as called for by the construction manual). Now I am torn between following the manual or using something less than 3.5 degrees to yield a more "normal" in-flight nose up/down attitude. Then I ask myself, "If I use less than 3.5 degrees at the fuselage, what happens to the normal wing tip washout of +.5 degrees...does it become negative? stay the same or what?" I don't want to make a decision to use less than 3.5*, epoxy the spars into position, and discover that it won't work. I thought about waiting until I could speak to builders at Mount Vernon but am ready now to set the spars. Any opinions and other ideas would be appreciated. Also, does anyone know of an EAA tech counselor in Northern Illinois? I couldn't find one on the EAA registry.
