Guys , we have been making laminated foam /ply structures for years and years ...WINGS ... thay have to be strong .... I would suggest making the frames(outsides/attachment points , etc.) first ... add the foam , and the Home Depot pink foam is fine as a structural component, or the Blue foam ...The white bead foam is not as good as the others , but will work , because the strength of the panels is in the skin, and the further apart the skins the stronger it will be (to a point , of course ) we used a contact cement for wing skins ... Southern Sorgum.. Was water based and did not eat the foam .... all other Contact cements eventually would eat the foam in the heat of the Sun ... Vacuum bagging is the way to go for these and is not that hard and produces superior results (and smooth surfaces.... Epoxy is a good adhesive , but heavy , and very expensive ... Pu glue and that expanding business may give you some trouble ...
I've been chided about over complicating my TD , seems like this might be a dead end street , for the same reason ... no real advantages over proper proven TD construction techniques....
I will however be willing to discuss at length , foam skinned structures, of which I have some experience...just not in TD's ...
