2.4 Construction Stage - Wing
The material for the sheeting of the wing should be cut in each phase of construction.
Some small pieces, however, are not shown here. Therefore, do not throw away the cut off
pieces.

2.4.2.2 Construction of the Center Wing
The printed plan must be glued together from the individual pages.
Tape he plans together using the alignment marks on each page.
Use a long ruler to check alignment of plans. Spar lines should be straight. See below.
First the 6x2 mm spruce spars are cut to length, slightly oversized.
Now a 1.5mm balsa sheet (bottom sheeting) is glued to the edge of the spruce spar.
Care must be taken to ensure that the parts are accurately aligned. The balsa can
now be cut off at the front, but it should extend about 5 mm in front of the ribs.
The balsa that is cut off should be saved for possible use in the future.
