If anyone is wondering what a "Wonder Wing" is, or how you make one, that was a separate FOTW article many years ago by Al & Gretchen Beatty! I have the articles url address below....
Those Amazing Wonder Wings!
I have both articiles availabe for download to you computer in pdf (requires free adobe reader) for viewing.
The Wonder Wings article 21 pages long, but that is because of all the photos.
If you have never heard of "Wonder Wings", wonder no more.
