This is my 1974 Bellanca Citabria 7KCAB, N90AV. It had a 150hp Lycoming IO-320 with inverted oil and fuel. It had a KY97 and Fly Buddy Loran. I flew it to either or both Oshkosh and Sun N Fun every year. I owned it from 1990 to 2000. It was sold it when I needed room in the T-hanger to finish my RV-6.
