18m polar curve

[Alan Irving]

Can anyone supply a polar curve for a current 18m sailplane?
Ideally the Ventus 2cxT, although Schempp-Hirth polars
seem to be unobtainable.

I already have the Dick Johnson review of the ASH-26E,
so will use the polar from that if all else fails.
That said, if anyone has a curve for a DG-800/808
or LS6c-18 I would be interested to see it.

Thanks
Alan

LAK 17 (18m) polar as measured by the German Idaflieg is here:

Also, Dick Johnson measured the LAK 17 polar in the July 2001 issue of
Soaring.
