That will work out about right with WW's 7" forward of the seat back/bottom intersection, except for the morbidly obese pilots who will always have to wheel land the airplane because their gut would interfere with full aft stick for a 3-point landing.

When you mentioned the Brodhead newsletters I dug out William's article on Piet W/B for Continental powered ships. He had calculated pilot CG location for each of the airplanes he weighed. The location is very close to what you had calculated. The mean of the values was about 7" forward of the seat bottom/seat back intersection. Now I need to figure out how I fouled up the calculation from Mr. Pietenpol's 1966 W/B sheet. I think my assumption as the where there is 8 gallons of fuel stored was incorrect.

The data William Wynne collected on Piets pretty much confirms it as being correct.
