Thanks for information
a little summary : there are 3 kind of one piece wings (I don't account 2 pieces wings's Oxalys)
1) foam and balsa 8 mm TE wing sold by ZNLine and includes in kit Oxalys
2) foam and "kraft" paper sheet 8 mm TE wing, special build by familly PLR.
3) composite wing of TS Composite with thin TE

The design of the wings item 2) and 3) are different of wing's Oxalys kit.
Cord in middle of wing's CPLR lenght is different of 1 cm and the "fléche arriere" is more little. At end of wing, distance between at the arriere of wing and horizontal line is more little.
