Thanks for posting those links. They have a lot of interesting info.
I believe the wing struts of the Herr kit are just small strips of balsa with wire attached at the ends. Since no photo is available, could someone describe how they are constructed? My plane already has attachment tubes glued to the wing and fuselage mounting locations. I have the instructions from Sig that includes a small plan. They indicate balsa but there is no description of the mounting system.
