Hi Jacopo,

There are 2 reviews published for the LS7-WL: https://www.segelflug.de/tests/LS7-WL/LS7-WL.html (in English), https://www.segelflug.de/tests/LS7-W...berichtLS7.pdf (in German).

Regarding the performance: both version were measured by Idaflieg. The LS7-WL had an LD of ~1:40, the LS7 had 1:43 with a significantly less sink rate at speeds above 160kph. The WL was marginally better between 130 and 160kph. The measurement was done with two different gliders with a slightly different turbulator configuration, though.

It's a fun and nimble glider to fly with good glide performance (with tight seals and turbulators mounted per the maintenance manual). But it takes experience and attention for good climb performance.

Cheers,
Christoph
