That's a real shame but I understand as more money in selling kits I guess!
As has been discussed many, many times on this forum and others, the Master Series are John Overstreet's designs and initial designs were being used to make cheap knock-off kits. The commercial reproduction of kits also extended to the rest of the FT designs, so the decision was made to not release any plans publicly any longer. Please buy a FT kit or build one of the many other free designs available on the forums.
