That was Burt Rutan's particular gift to the state of the art.

A soft foam piece that was easy to develop into complex shapes,
and stayed in the part as a stiffening core.

Or remove the foam completely after layup, if it's not needed.

"Mold-less" construction.

True, but in lies the rub. It's just as much work to build one aircraft,
as the plug for a mold that will build many. Large panels and even two
piece fuse sections save a lot of work, and can produce even lighter
panels.


I don't believe that it is even 20 percent of the work needed to build a
reusable plug--and it is certainly less than 10 percent of the work needed
to build a plug plus a reusable mold.


Why do you feel it's more difficult to build a plug, than a fuse section?
