Has anyone succesfully generated Polars for the DS-19 (and mods.) using the Profili X-Foil generator?

I get an error message that "zero of the 70 coordinates present".

I've tried 'Smoothing', increasing the 'FILT value' in X-Foil and I've recomputed the Polars all with no luck.

Anyone have a trick for doing this?

Thanks,

T.D.

Have you joined the Profili group over on YahooGroups? I'd try there.

Thanks for replying Gary,

I solved the problem, one digit in the coordinates that I downloaded was incorrect and I only found it after comparing what I had with what Joe Wurts posted here.

In case your interested, thicken the DS-19 to 8.98% with 2.25% camber and check it out...really a great looking section. Very very close to the JW-19 as used on the Icon I think.
