Sure! a big man can fly. The thing you need to look at is the wing
loading. I don't think the Rand company is correct for the wing loading
so lets use Larry's airplane even though he says theres no way. gross
wt.=1100 lb, S, wing area= 77sq.ft. ( he has clipped wings so its less
the the 80 sq.ft. of Rand ) Now, the wing loading of Larry's plane is
W/S = 1100/77 = 14.28 lb/sq.ft. now, you weigh 60 lb more than Larry and
you want to carry a small passanger like 100lb. so your gross weight will
be 1100+60+100 = 1260lb so you want to keep the same wing loading, so
wing area should be S=1260/14.03 = 88 sq. ft. Now since the center
section of the wing chord is 4ft.,you can get this increase in wing area
(11sq. ft.) by increasing the center section by 11/4 =2.8ft. by adding
1.4 ft. to each side of the center section of the wing. This will also
increase the Aspect Ratio of the wing which will increase the climb
rate. This will change the structure slightly but the spar caps of the
center section can be increased to beef up the structure to componinsate
for the extra bending moment.
Happy flying
