Default LS-3a Polar Info. Wanted.

I've recently purchased an LS-3a. My P.O.H. does not include a Polar Curve Graph, so I'm having difficulty finding difficulty in finding speeds for Min. sink, speeds to fly in Headwind/Tailwind, and in sink. Any Help is appreciated.

The Johnson flight tests, available from the Soaring magazine archives, have the information you need.
Good Luck

Paul at Cumulus Soaring has a polar page including LS3. http://www.cumulus-soaring.com/polars.htm Excellent resource.

You can cross-check the LS3a polar to make sure it is close enough (it should be).

I'm not sure if it is helpful, but the uploaded files collection of the LS gliders forum in Yahoo Groups (https://groups.yahoo.com/neo/groups/LS-gliders/info) has copies of polar graphs from an LS-3 (not 3a) POH.
