Yes, there is a great write-up on Les James's Rotec radial powered Kitfox in the latest PFA Mag. Ive seen it flying too, seems to perform well and sounds great!
The article mentions poor handling with the ailerons fully drooped and that its better to not use any flap at all- just sideslip.
I havent flown a Kitfox but here lots of advice that because of the low inertial, they are a bit of a handful in gusty crosswinds. But I guess if you respect the crosswind limitations, then maybe ok.
I did fly a couple of Avids which are very similar. I found the clipped wing version much nicer to fly, than the long wing version. The long wing version was I believe very similar wing to the early kitfoxes.
A friend of mine had a Kitfox for quite a few years and flew it all over the place and had a great time with it (sold it when his RV-6 was finished) There is another guy in Scotland with one who flies all over the place and has lots of trouble free hours, except his landing at the beginning of the PFA rally last year- but it was flying again not too long after I think
