I can understand getting bored with a go fast airplane. If you don't have a need for high speed travel the Kitfox is a lot more fun to fly, as you can go places the go fast plane can't, and you can enjoy the scenery more, as you can fly low and slow much safer.
Besides being so much fun to fly, the Kitfox truly is one of the most practical aircraft to own as it has to be one of the most versatile aircraft ever designed. It is a decent back country bush plane, a great ski plane, a fantastic float plane, and a very reasonable cross country cruiser. And fuel burn will probably be half of most other aircraft. So there isn't much not to like.
With your building skills, if it were me I would build a new Super Sport. If you can use a reasonable priced used engine, used radios and instruments, prop, etc, you could end up with a really valuable late model Kitfox that is done just the way you want one. And you will have less money in it than what you could buy one for.
You're right, not too many of us are willing to give up our Kitfoxes. And that situation seems to be getting worse, not better lately. But the good thing is that the factory still sells kits![]()
