Substitute filler

[Ian Robson <ian@robson54.freeserve.co.uk>]

My colleagues and I are at the end of constructing the first stage of an xs 
model,
and were thinking of using the superfill filler produced by Polyfibre,  as
opposed to the standard filler supplied by the factory. We saw it at the 
Cranfield
PFA rally and it seemed pretty impressive. Does anyone have  experience
of the system, or hold  views on substituting the material?
