I am the 4th owner of this airplane. It was built by Kent Sibley in Missouri in the late 1980's. I bought it 4 years ago locally. I have re-installed the smoke system, added a spinner, re-painted the wheels pants to better match the paint scheme, installed a new 2 place intercom, added a transponder and mode C, purchased new seats from Oregon Aero (I love em!) and had major fun with it! It has a Christen inverted fuel and oil system and coil spring gear system. The only problem with it is our winters. But it just makes spring that much better!
