There is a guy that picked one up at a auction and the top wing was a mess with a nice twist in it too so he decided what does he have to lose, He got it cheap so he just put the bottom wing on, changed the CG and let her rip. Flies well too but is a bit faster than it would have been with more wing area (higher wing loading) But still flies great. Building the Hog bipe myself but plan to keep both wings.
