In many area's on my wood structure it calls for a filler. Usually
spruce, but for no other reason but to fill a gap. These are not
structural in the least, only to fill (i.e. on top of the spar a 1/4"
strip of wood to keep the plywood skin from saging in between the wing
ribs). Has anyone used Balsa wood to accomplish this to save on
weight. There seems to be alot of little areas like this in my plans.

The only place I used balsa was on the fairing to shape the back of the nav
light housings on the wing tips. While every ounce counts, is there really
that much cubic volume where the difference between spruce and balsa would
add up to a significant amount (on the cheeseburger scale)?
