All wooden parts are affixed by paste Chs-Epoxy 371. Polyester fabric facing is affixed by contact paste Chemopren 140. Glassy-laminate is from epoxide resin Chs-Epoxy 512 or L 285 with glassy reinforce Vertex.

The wing is divided in the middle between two half, both of the half are connected to the Centroplane by pegs and they are supported by fraces. Bearing part of the wing is created by torsion case, which is consisted of wooden girder and laminate cover. Strips of the girder are made from spruce wood, standing from birch or beech plywood. Form stableness is safed by foam polyester ribs. The ribs which create back part of the wing are sticked from spruce Listels. Back part cover of the wing is from polyester fabric.
