Hi All, I would like some advice on the Kitfox IV classic. There is one for sale here in Aus. I am thinking of purchasing. It has a Subaru engine in it that I would like to change with a Rotax 914. Will the airframe handle this engine ? What is the wing like on the classic ? I would like to end up with a respectable STOL plane. How much different is the stol wing for Kitfox compared to this ? Are they interchangeable ? Go easy Im new to kitfox planes and trying to understand the differences . Cheers
