Nimbus 2c wing templates

FWIW, I just posted a corrected FX-67-170 DAT file on gliderforum.com under
the Nimbus 2 group. I didn't correct the TE error since I don't think that
will matter to anyone.

I'm hoping that someone here can provide it - or else the information
that would allow me (with the aid of a spread sheet) to generate the data
needed.

The FX-67-170 inner wing and FX-67-150 outer wing airfoil coordinates
available at the NASG airfoil database in a .DAT format. See:
http://www.nasg.com/afdb/list-airfoil-e.phtml

Just be advised that the FX67k170 coordinates at the NSG database are
probably not the best to use. There was originally an isue with airfoil
smoothness with some of the published coordinates from Stuttgart. In this
particular case, the leading edge is not quite smooth, and there is a very
obvious error with the sign of the y-coordinate on the lower surface near
the trailing edge (probably not important now, unless you are planning to
re-profile the flaps as well). There are some smoothed and corrected
coordinates around, it would be better to get those.
