Rich,
We very highly recommend Barnaby Wainfan's BW 05 02 09. Smoothed
coordinates (200 points) are on our web site. According to XFoil,
this section has a zero lift angle of -0.33 degrees and a pitching
moment of 0.014. The pitching moment is sufficient for stability and
achieves low drag. The area near the trailing edge is thick enough
for a strong sheeted structure. We've used it on the original
Blackbird (2 meter span) and our latest Blackbird XC (2300 sq. ins.)
with great success.
All of the BW 05 02 09 information is available from links on the
B2Streamlines home page http://www.b2streamlines.com.
What's the best airfoil for a plank flying wing, built-up not bagged?
