Europa-List: Modification to Wings

[Peter Timm <cptimm@telus.net>]

Just finished installing the mod. 74 wing-root pins and it occurred to me,
that filling the cavity drilled out of the blue foam could possibly be done
with expanding foam. I have used this material before for other applications
and find that it sticks to anything and can  easily be sanded.
Has anybody tried it, or could there be problems ?
