Default Polar data for The Rhönsperber

Hi everyone,

Does anyone have, or has a link to a polar for the Rhönsperber or the figures to enter in SeeYou Mobile?
All I have at the moment is the data from Peter Hocker's book on Hans Jacob but they are not enough...

Many thanks,
Daniel

If you have any data - say, sink rate at 3 airspeeds, Paul Remde's nice polar spreadsheet can calculate the coefficients for SYMobile.

I recently did this for another classic glider, but had a polar curve found on the web to sample.

Try reading the 1946 March April issue of Soaring Magazine and look for a good comparison. The March April 1950 Soaring magazine has a polar of the Zanoia which is probably a close but not exact fit....
