I did some basic calculations on the wing used on the Chuckbird/Texas
Parasol
before building my first one. I came up with a shade over 4 G's at 650
pounds.
(seemed like a good idea before selling plans)

Then got Nuked by several guys who claimed the wing was "weak" - because
they
were building 650 pounds - EMPTY.(and it was my fault!?!)

E-bleepin'-nough!

I have to admit he does bring up a good point. I have often wondered
what the difference in strength's and weakness would be if I used
different wood in my plane, or enlarged the components for a larger
pilot. Most every calculation I need to make comes from an average, if
not a guess.
