I believe that Francis Donaldson (PFA's Chief Engineer) advises anybody building or buying a Kitfox to go and get some flying hours first with an instructor in a Thruster taildragger, which has similar high drag/low inertia/tailwheel characteristics. Thus trained, I think that most people find it a delightful aeroplane.
It had a very had reputation in the UK at one point, but I believe that this was basically down to pilots trained in aircraft such as the C152, with very different characteristics, going straight from those to the Kitfox, and they just couldn't cope with it. In the USA, where draggy taildraggers are much more commonplace, there wasn't really any such problem and the Kitfox has a very good reputation.
It's also likely to have an older technology 2-stroke engine; go and spend some time around microlight pilots who should be able to help you learn how to live with one happily. They're good engines by and large, but Lycomings they ain't!
