It's amazing how a trip to Oshkosh can clear your mind. I've now decided that the Jabiru J250 is just too darned expensive, at least for what I get. And since I now know that a Jabiru engine can be put on a Kitfox, the Kitfox Super Sport is now my choice. Before going to Oshkosh, I thought the Rotax was the only choice for the new Kitfox. Also, since the Kitfox can be ordered in stages, unlike the J250, I can get started on building sooner.
