Hey guys,
I am trying to find out if there have been aircrafts that used steel spars & so far it looks like the "Thrush" line of cropdusters are the only ones. Are there others out there? Any pictures of the spars? Is the construction similar to an aluminum wing (laminated angles and rectangular bars)? Why don't we see more of these? Aren't steel spars perfect for an aerobatic aircraft?
