I did not but I tested the engine thinking that I might put one in my Hellcat. The 90SP that I had ran well and was easy to start but did not produce much in the way of horsepower. I flew it on a 9 pound Hangar 9 Hellcat and it was just barely adequate so I knew it would never work satisfactorily in my 11+ pound scratch built airplane. If you do decide to move forward keep the Airacobra as light as possible.
