pizza plane

Hi there is there a way to scale the pizza box plane? I just found 2 scaled versions (from the site from the build video) + has someone experience with the mini corsair buid out of cardboard?

This idea came from reading a post from Andras, aka Sunshine, who wrote of making a plane with gingerbread. My thought is this: Who can build an aircraft using the least amount of non-edible stuff. The winner would be determined by flying the aircraft to prove air-worthiness and then eating it...
