I am involved (again..) in getting N38K back in the air. This is the prototype S3B (2 place) Playboy. I never have had drawings for this (my second re work of this great airplane) and the last owner chopped the two place seat and made a few mods. We are trying to restore this to honor it's place in the homebuilder world. If anyone has a set of 3B plans we would gladly pay the cost of having them scanned (Staples/Kinko) so we can keep a set with the airplane and verify/replace incorrect mods.
