It seems to me that the actual WL used in the initial jigging of the

aircraft is somewhat irrelevant to the task at hand if I have been following this correctly. What we need to do is establish the "relative" angle of incidences between the main and canard. Additionally it would be nice if there was a quick way of putting a measuring device on the prop flange to determine its orientation to the canard and BL 0. The actual angle that the fuselage has while flying, to me at least, is of secondary concern. A "misalignment" of 3 full inches when the fuselage is initially jigged up is only about 1.2 degrees and is probably as much as anyone would have messed up even if they used the split lines for the water lines. I don't see 1.2 deg making much difference in the drag of the fuselage or it's interaction with the lift of the wing(s). This should simplify the measuring process. Wish I had time to attend Ottawa and help out but I just don't see it happening this year. For sure next year, and I plan to fly..........in my Q =======================================

We'd also need a way to reestablish the waterline on each ship being measured. Some of us may not have installed a bubble level into the fueslage at the time of building, and since the initial jigging of the fueslage is arbitrary at best, one simply can't use hard points such as the top of the rudder fin, or the forward edge of the canopy. >> "Think outside the box - but fly in the envelope" <A HREF="http://hometown.aol.com/bd5er/Qpage.html">Q-2 page</A> Leon McAtee
