Thanks for the replies, I know it will be way over powered with a 91 FS. The 65 2 stroke in my last one would almost hover and it flew nicely on 1/2 throttle or less. I just hate buying a new engine and figure I could just putt around on low throttle settings, I'm not looking to do anything wild with it. It is a great flying plane and I really like it as a tail dragger, it makes an average pilot look really good. I don't get to fly as much as I would like to, this is a nice relaxing plane to just cruise around with. Thanks again.
