Help! I need plans!

Where can I find the plans for the FT Guinea Pig?!? My local RC club is having a community day in 2 weeks and I'm wanting to build a Guinea Pig in case my buddies Big Balsa planes Candy drop box fails again. Printer planes or plotter plans are what I'm looking for.

Ok so I found the plans, now I just need to figure out how many sheets of foam should this thing take?
