Keith,
There is a seller on Ebay who goes by "Scientificsupply" that offers plans for the Flying Fool. You might look that name up in "search" on ebay and contact him about the plans if you're interested.
The last time I checked, most of his plans sold for $9.95 plus shipping. I got a set from him for a Sterling Super Ringmaster awhile back. The plans are a bit crude, but useable.
Good Luck,
Joe
