Is the 42" SIG Shoestring still available in kit form? I've looked at various websites and can't find one. I have one that I bought at a flea market and it's been into the asphalt 3 times now. It only had a broken off rudder from the first two crashes. Toughest plane I've ever owned. It wasn't running right on Friday and I pushed it when I knew I shouldn't have and it shut off straight above me during an overhead 8. It went straight down and hit so hard that it broke the front holes out of the OS Max-s 35 and sheared the back motor mount bolts. All it did to the plane was separate the outboard trailing edge, split about 4 ribs and the rudder came off. I had it back up in the air 24 hours later and it flies better than ever and the engine runs better than ever. If I had known that I would have crashed this thing a year ago. Anyhow, I like the way this plane flies so much that I wouldn't mind having another one.
