Hi all, I'm looking for an alternative foam core wing skin material. Something other than the traditional balsa, obichi ply, or low temp iron on covering. I have an old Filtecraft ARF which has a thin, yet tough skin on the wing which is plastic coated. I wish I could find that stuff but the manufacturer is out is business. There's thin polystyrene sheet material like those orange and black "for sale" signs, but I can't find it in bigger sizes suitable for skinning a wing core. Anyone have any suggestions or comments? Thanks!
