Supposedly, the molds for the Great Planes Tiporare, Illusion, dirty birdy as well as others were all sold to Kitty Hawk Models... which doesn't seem to be in business anymore. So I'm guessing these prized treasures of aeromodelling history are sitting in some storage closet somewhere.

You can buy the plan from "Bill Northrop's Plans Service" and it is plan #2801.

I'm going to be scouring the swap meets this winter to try and find a good deal. Hopefully, they won't know what they've got.
