So I phoned Titan to ask them how they do it in their Tornado and this is what they said. The Wing is conventional metal from the metal builtup main spar to the rear spar with metal ribs and the aluminum skin riveted thereon. The front of the wing has foam ribs with the skin glued onto them. I missed asking about the skin. Is there separate skin back to the main spar or does one skin cover to the rear spar?
Anyway, it seems to me that one might build a KR with the wing skinned with plywood over foam from the front spar to the rear spar and aluminum over foam for that part of the wing. I think it would be legitimate to use screws to attach the aluminum to the spar because it is doubtful if one could obtain an acceptable glue based attachment. I guess this would make the ac more Taylor than KR. To argue further, wouldn't skinning with aluminum be as legitimate as using Deihl skins? But the sanding song is important to the KR culture.
