I'm looking to buy a challenger II, it has a 2703 Hirth engine in it. I have heard they are only good to recycle for beer money or they're great. One guy claims if you take care of them and use an egt and the right oil they will last. Anyone have any input on this engine. I can get the plane for around $3000 but if i have to put a Rotax in it I could be way too far out for a fixer uper.
