Jim thanks for the come back on my message, I figured cord, span and wing area and for me it came out twice at 5 5/8 inches. you and I must be right in the ball park. It rolled about 50 feet and lifted off nice and smooth, landing was a dream just a little up elevater to keep nice glide angle. See you at sommerset.
fair winds and blue skies
