Some folks asked where to get Fiberfrax. See http://www.aircraftspruce.com/search/search.php . I think I used 1/8", but 1/16" is supposed to work fine. I guess that's another reason my plane is heavy, although fiberfrax is a tiny fraction of the weight of stainless steel, and that was my logic in the tradeoff between steel thicknesses. Last time I checked, Rand Robinson sold thin stainless sheet. I'm guessing that means NVaero might sell it now, but I'll leave that to Steve to comment on. High temp silicone should be an acceptable adhesive for it, so I've heard.
