It's interesting that while the whole airframe has been laser cut, the wing ribs were only cut to a basic square cutout (which is not terribly strong), when the CAD could have cut out scale like triangular cutouts, which would probably be a little stronger. I know it doesn't really matter as model are so ever built compared to full sized aircraft.
Radku, gratuluji k záletu tohoto nádherného, detailně a pečlivě zpracovaného modelářského skvostu ! Už se těším, až je proženeš na velkém svahu v Alpách nebo na akrobatické soutěži SCALE větroňů :-) Petr
