- Yup.

- Ever heard of a parafoil? They tend to use airfoils for risers. ;-)
-
- I was looking for the program for a friend of mine who's planning on
- building the "Sputnik" from Nop Valthuzien's (whose name I've
- probably butchered) book. The plans include a table of data for
- creating the airfoil section, and plotfoil is particularly well suited
- to take this sort of data and turn it into a nicely splined output of
- your preferred chord. The poster who original talked about plotfoil
- way back when had used it to build the Speedfoil from the same book.
-
- For what it's worth, the latest KiteLines had a Design Workshop article
- on an experimental stunter with a cambered wing which was modeled after
- a particular airfoil.
