Thanks guys, the Rans S10 seems like the best available secondhand a/c with a very good history, although I've heard a few voices of dissent in the past - more like a lawnmower then an aircraft, uglier then my mother-in-law etc. But judging by a recent drove of Rotax fuel consumption and maintenance threads it's cheap to run and maintain and seems reasonably challenging to fly, essential if I'm to build up reasonable skill. My goal is a Pitts, but one thing crops up about the S1C/S - they're very cheap for their capabilities - why?
