Symmetrical airfoil

I have used the symmetric and low Re number Eppler 168 section on a .15 gasser and an Astro 05 electro. It worked well.

Coordinates: http://amber.aae.uiuc.edu/~m-selig/ads/coord/e168.dat

A coarse plot: http://amber.aae.uiuc.edu/~m-selig/ads/afplots/e168.gif

The database: http://amber.aae.uiuc.edu/~m-selig/a..._database.html

A plotter program: http://www.baronerosso.net/software/...profili1_2.htm

Have fun!
