I took a cursory ( inadequate ) look a couple of years ago. The silica 
materiel would be totally adequate for our purposes and save almost our 
entire wing core weight - with enough compressive strength to be bagged. The 
info I found indicated the cost would be in the thousands for one wing panel 
and there were shaping problems.

I  have about 20 flights on a new wing, 1# core, bagged with 2mm Rohacell 
and .2 oz carbon mat in lieu of balsa. The Rohacell manufacturer has a new 
grade, IG-F, 3.2 #/ cu ft, which is only availiable from Germany at this 
time, and is very suitable for our needs. It is not availiable from CST. The 
compressive strength of this grade is about the same as 12# balsa and  has a 
fine pore structure.

The 430 sq in wing panels weigh 10.9 oz "glassed" and painted.
