    Well now I'm curious. When I did the W&B on my airplane (calibrated digital race car scales, first W&B done by me after repairs were completed and second W&B done after I changed the A65 to A75, done by an experienced Tech Counselor who has done dozens of weighings), we weighed the airplane empty and then again with me sitting in the cockpit, so the 49.64" aft of wing leading edge is pretty accurate on mine. My wing is inclined backward 4" and mine is an Air Camper, not a Sky Scout. I'm going to go back to the measurements that I took to see where that places the pilot's CG relative to the bottom corner of the pilot's seat. -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=472581#472581

    Oscar, By my estimate your pilot CG at 49.64" from the leading edge leaned back 4" would be about 11" forward of the seat back and bottom interesection if your plane is built according to the long fuselage plans. Or about 7.5" if the seat back is at a 15 degree angle as Ray built his Sky Scout. I imagine it is somewhere between those two values. Can you guys tell I retired this summer and have way too much time on my hands? Doug Read this topic online here: http://forums.matronics.com/viewtopic.php?p=472583#472583

    Doug; my seat back is not angled back any amount from stock, or at least I don't think so, but that makes me wonder even more! I shall put the angle finder on the pilot's seat back next time I'm at the hangar! Anyway, 11" forward of the seat back/bottom intersection sounds pretty good considering that in the last 10 years I have progressively lost sight of my "lower anatomy" behind the growing crest of a beer belly (a desk jockey belly, actually), and have gone from a 29" waist to a 33" waist at the belt line but considerably greater above that line. I don't know what has happened there. Now let's see: if I were to calculate the center of mass of the bulge that is above my belt buckle, adjusted for the distance that my belt buckle has disappeared over the horizon, multiplied by 7" and divided by the wing area, multiplied again by the gross weight of the aircraft- the result (rounded to the nearest decimal place) might be the time in hours and minutes that I can fly at normal cruise between potty stops. Adjusted for headwind, of course. -------- Oscar Zuniga Medford, OR Air Camper NX41CC &quot;Scout&quot; A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=472604#472604
